ABSTRACT
Slovakia and Hungary have consistently opposed accelerated plans to end imports of Russian oil and gas, emphasizing economic risk and infrastructure shortfalls. The European Commission’s 17 June 2025 proposal, “Proposal for a Regulation on phasing out Russian gas imports and improving monitoring of potential energy dependencies,” mandates that new Russian gas/LNG contracts be prohibited from 1 January 2026, existing short‐term contracts terminated by 17 June 2026, and full phase-out of both pipeline and liquefied natural gas by 1 January 2028, with oil diversification plans required by 1 March 2026 and a complete stop to Russian oil imports by end-2027. (European Commission Proposal, DG Energy, 17 June 2025)
Slovakia has declared readiness to consider import reductions only once transport, storage, and alternative supply infrastructure exist. In March–April 2025, Slovak Minister of Economy Denisa Šaková stressed that abandoning Russian resources prematurely would inflict serious damage on heavy industry and economic stability. During talks in Vienna with U.S. Energy Secretary Chris Wright, she reiterated Slovakia’s conditions for any reduction: viable alternative sources and sufficient pipeline or interconnector capacity. /// Hungary has adopted tougher rhetoric. Government Minister Gergely Gulyás has stated explicitly that Budapest will veto any European Union decision that threatens national energy security. Foreign Minister Péter Szijjártó has negotiated long-term contracts with non-Russian sources while maintaining that energy purchasing decisions are a matter of sovereignty.
Data from Reuters confirm that oil continues to flow via the Druzhba pipeline into Slovakia and Hungary; after temporary disruptions in August 2025, supply resumed. Slovakia declared flows “standard” with limited impact expected. Hungary too emphasized minimal disruptions; company MOL reported production unaffected during downtime. (“Oil flows resume via Druzhba …” Reuters, 20 August 2025)
The Slovak government projects that national natural gas imports from Russia will decline, especially in the light of the Ukraine-Russia transit deal expiration at end-2024. Slovakia declared itself “prepared” for the interruption of gas transit via Ukraine, though Saková criticized unilateral Ukrainian actions and emphasized ongoing negotiations with both Ukraine and Russia to maintain flows. (SP Global, 31 December 2024)
The European Parliament Research Service (EPRS) in its 7 July 2025 Briefing (Document EPRS_BRI(2025)775863) underlines that Hungary and Slovakia are among EU members most exposed by pipeline dependence and long-term contracts with Russia. The Briefing notes that projected production from Romania’s offshore field Neptun Deep (estimated ≈ 8 billion cubic metres/year (bcm/year) beginning 2027–2028) could assist diversification in Central and Eastern Europe, but that land-locked countries’ limited access to seaports and LNG terminals amplifies dislocation risk. (European Parliament, 8 July 2025)
Hungary has maintained import volumes from Russia via TurkStream and pipeline networks, despite signals of seeking alternative contracts. Hungary rejected energy sanction proposals in past EU sanction rounds, citing disproportionate impact on its economy and violating national competence. In September 2022, Hungary’s chief of staff Gergely Gulyás declared inability to support new sanctions containing energy provisions. (Reuters, 29 September 2022)
Slovakia’s reliance on Russian oil via Druzhba avoids the seaborne ban that other EU members face. In August 2025, the Slovak Economy Ministry stated that despite external damage to parts of the pipeline network, monthly volumes would remain largely intact. The Ministry noted two infrastructure disruptions in one week but expressed confidence that resumption of normal flows will stabilize supply. (UNN via 20 August 2025)
European Commission officials, following meetings with U.S. Energy Secretary Chris Wright, have reiterated that while the legal proposal includes conditional delay mechanisms—such as allowing short-term contracts signed before 17 June 2025 to persist until mid-2026, and some long-term contract transitions until end-2027—it expects all member states to submit diversification plans by 1 March 2026. (Proposal Regulation, Article 24 and timeline provisions)
Slovakia has also begun collaborating with Ukraine to explore transit and joint supply projects. In early September 2025, Minister Šaková affirmed that energy cooperation with Ukraine will proceed “where interests coincide,” including in joint infrastructure projects. A transmission facility project via Mukachevo-Velke Kapusany (electricity and possibly gas) is targeted for implementation in 2032, though gaps in alignment over timing and legal frameworks persist. (TASS via Slovak economy ministry, 5 September 2025)
Hungary’s position emphasizes that even if Ukraine were an EU member, it would still lack authority to determine from whom Hungary may purchase energy. Gulyás has insisted on national sovereignty around energy contracting and warned against EU measures that would infringe on existing contracts or require Hungary to accept costly alternatives without compensations. Foreign Minister Szijjártó has meanwhile been pursuing long-term gas contracts (outside Russian supply) to demonstrate diversification, though details of volumes or timelines are often withheld in public sources. (abouthungary.hu, 25 August 2025)
The Commission’s proposal includes legal safeguard clauses recognizing exceptional circumstances: for instance, land-locked member states tied to long-term contracts are granted transition allowances until 1 January 2028. That exception appears tailored to chronic dependencies evidently present in Hungary and Slovakia. From the proposal document: contracts under long-term arrangements existing before 17 June 2025 may continue until the end of 2027, while special geographical or infrastructural constraints may be considered. (Proposal Regulation, Articles on transition and exceptions, 17 June 2025)
Slovakia’s energy sector is heavily industrial, with large steel, chemical and automotive subsectors that depend on steady, affordable baseload energy. National statistics show industrial electricity and gas consumption comprises a majority of Slovakia’s energy demand; abrupt supply changes risk cascading impacts on employment, trade balance, and inflation. No verified public source provides a quantitative GDP exposure for Slovakia specific to Russian gas phase-out beyond what is in EPRS and Commission documents.
Hungary’s energy mix similarly features large thermal generation, heavy industry, and limited indigenous fossil fuel capability. Hungary has invested in nuclear (Paks), and in some renewables, yet lacks sufficient infrastructure for large scale LNG imports or alternative pipeline capacity. Hungarian authorities argue that EU proposals underestimate costs of converting or replacing infrastructure, securing new contracts, and guaranteeing price stability.
The EU’s dock-to-door LNG terminals and pipelines network has multiple bottlenecks in Central and Eastern Europe. The Commission’s own impact assessments acknowledge landlocked states will incur higher per-unit costs for switching to non-Russian LNG sources. The proposed Regulation’s financial statements indicate that subsidies or transition funds will partially offset costs—but not entirely—and that delays in national diversification plans increase risk premiums.
Economic forecasts in Commission documents suggest that accelerated phase-out absent adequate supply alternatives will cause energy price spikes, dampen industrial output, raise inflation by up to 1.5–2.0 percentage points in adversely exposed states for 2026, though these are modelled under high dependency scenarios. Public sources, including EPRS, confirm that Slovakia and Hungary are repeatedly flagged in multiple CESEC (Central and South Eastern Europe) assessments as high risk due to legacy contracts and lower alternative import infrastructure.
Hungary maintains existing contracts with Russian suppliers through TurkStream and pipeline networks and continues to rely on oil via Druzhba*, creating exposure to sanctions, legal risk, and disruption risk from infrastructure attacks. Slovakia similarly remains heavily dependent, particularly on oil via Druzhba and gas transits through Ukraine, and has concluded no publicly confirmed large-scale non-Russian long-term contract sufficient to offset anticipated cut-offs by 2028.
The stalemate between the EU’s accelerated phase-out timelines and Slovakia’s/Hungary’s conditions has generated legal and political friction. Both governments have threatened vetoes of EU decisions or Council statements that they regard as overreaching or insufficiently compensatory. Slovak government under Prime Minister Robert Fico has criticized proposals as “absolutely unacceptable” in some public statements. No verified public document confirms any financial settlement or compensation proposal from the EU explicitly accepted by Slovakia or Hungary that would offset all transition costs.

Structural Evolution of Slovakia and Hungary’s Energy Dependence on Russian Hydrocarbons, 2022–2025
The legal fulcrum of the regional oil shift rests on Council Decision (CFSP) 2022/884 (June 3, 2022) and the companion Council press release (June 3, 2022), which imposed an EU embargo on seaborne Russian crude from December 5, 2022, while allowing a derogation for pipeline deliveries via the southern branch of Druzhba to Hungary and Slovakia to avert immediate supply shocks to landlocked economies. The regulatory scaffolding and timetable are further codified through [EUR-Lex consolidation of the sanctions framework under Regulation (EU) No 833/2014 and its amending acts, including Regulation (EU) 2022/879], as well as the Council’s running guidance on scope and permitted transactions, captured in the Commission’s Consolidated FAQs on sanctions (January 2024). The carve-out preserved crude feedstock for Bratislava (Slovnaft) and Százhalombatta (Duna) refineries while preserving the strategic intent of progressive decoupling through bans on maritime imports and service restrictions, a design summarized on the Council’s live explainer page on Sanctions against Russia.
Gas-system resilience over 2024–2025 is described by ENTSOG’s quantitative security-of-supply modeling, which demonstrates that Europe can satisfy winter demand and maintain strategic inventories without Russian pipeline flows under reference conditions, and even achieve 90% storage fullness by end-summer 2025 with adequate LNG and Norwegian supply, as documented in ENTSOG’s Winter Supply Outlook 2024/25 with Summer Overview 2025 (October 16, 2024) and its follow-on Summer Supply Outlook 2025 (April 2025). The winter study explicitly constrains Ukrainian transit to expire at end-2024, shifts optimization toward LNG and Norway, and still shows no curtailment risk in reference winter conditions while indicating the volume of additional demand response required under LNG-low or cold-spell sensitivities, thus bounding security-of-supply risk for both Slovakia and Hungary under the cessation of legacy Russian route dependencies.
Diversification of physical routes into Central Europe accelerated through EU-supported interconnections and LNG evacuation corridors during 2022–2025. The Gas Interconnector Poland–Slovakia (GIPS), inaugurated on August 26, 2022, provides up to 15.6 million m³/day northbound (Slovakia → Poland) and 12.9 million m³/day southbound, according to the implementing agency CINEA’s official note (CINEA opening release (August 26, 2022)), thereby knitting Poddębice–Strachocina–Velké Kapušany flows into the Świnoujście LNG and Baltic Pipe mosaic and granting Slovakia scalable reverse-flow access to non-Russian molecules. The Hungary–Slovakia interconnector at Balassagyarmat/Veľké Zlievce adds bidirectional flexibility; ENTSOG’s most recent non-binding demand assessment reports tangible market interest in additional northbound capacity, with submitted indications totaling 30.38 GWh/day (about 60% of technical capacity) in the HU → SK direction, reflecting a reorientation toward north-sourced alternatives (ENTSOG HU–SK DAR (October 23, 2023)). The region-wide capacity lattice and cross-border interpoints are compiled in the ENTSOG–GIE System Capacity Map 2025, which locates Hungary’s interfaces to Slovakia, Romania, Serbia, and Austria, and Slovakia’s interfaces to Poland, Czechia, Austria, and Hungary, underscoring the structural feasibility of sustained route diversification even in the absence of Ukrainian transit.
Seaborne substitution channels into the Pannonian basin increased via Adriatic gate capacity and evacuation pipelines. The Krk FSRU has raised technical throughput to 2.9 bcm/year with compatibility for carriers up to 265,000 m³, per European Commission documentation collated in March 2023 (DG Energy Croatia energy profile extract (March 31, 2023)), while earlier CEF Energy project records specify 2.6 bcm/year send-out and an evacuation capability of 1.7 bcm/year toward Hungary (CINEA CEF Energy supporting actions compendium (September 2022)). Those official records frame a conservative lower-bound for feasible non-Russian gas inflows into Hungary, augmented by the HU–RO interconnection and the potential for additional Southern Gas Corridor volumes. The European Commission’s diversification dossier states that the Southern Gas Corridor delivered 11.7 bcm to the EU in 2024, a 44% increase versus 2021, and explicitly lists Hungary and Slovakia among the receiving countries (DG Energy diversification page, updated 2024). The cumulative effect of these maritime-to-inland corridors has been to reduce the exposure of both markets to single-route or single-supplier shocks while providing a platform to arbitrate between LNG hubs and pipeline sources on price and basis spreads consistent with EU internal-market rules.
Macroelectricity-gas linkages strengthened in 2024–2025 under high-renewables intermittency, strengthening the policy case for retained gas flexibility during transition. IEA’s Gas Market Report series documents a 6.5% year-on-year increase in European gas consumption in H1 2025 owing primarily to power-sector dispatch substituting for lower hydro and wind output, even as the EU continued to diversify away from Russian molecules (IEA Gas Market Report, Q3-2025 executive summary (July 22, 2025)). The same quarterly series indicates lower Norwegian pipeline supply in H1 2025 due to maintenance and a marked increase in EU LNG imports, showing that security-of-supply management increasingly hinges on storage injections and cargo inflow scheduling under tighter global balances (IEA Gas Market Report, Q3-2025). For Slovakia and Hungary, both heavily industrial and with limited domestic gas production, such dynamics elevate the importance of cross-border flexibility and adherence to storage mandates, as codified in Regulation (EU) 2022/1032 (June 30, 2022), which imposes 90% target fullness from 2023 onward and burden-sharing across member states without storage.
The storage mandate’s forward life is already the subject of an EU legislative dossier that acknowledges the regulations’ sunset at end-2025 and proposes a two-year extension to end-2027, thereby anchoring planning horizons through another winter-summer cycle of tight balances (EUR-Lex COM(2025) 99 context page (March 5, 2025)). The policy continuity feeds directly into ENTSOG’s feasibility results for 90% end-summer 2025 fullness in scenarios with minimized Russian pipeline reliance, and it is consistent with the European Commission’s interpretation of the storage regulation’s 80% (2022) and 90% (2023 onward) targets as detailed in its Communication COM(2024) 404 (July 2024). This legal-technical interplay underscores that the central risk buffer for both Slovakia and Hungary is regulatory, physical, and commercial: mandating volumes, maintaining cross-border deliverability, and aligning price signals for injections against global LNG opportunity costs.
The trade reconfiguration is evident in Eurostat’s official Statistics Explained series, which traces the collapse in EU–Russia goods trade from 2022 onward, with fossil flows curtailed by sanction law and self-sanction behavior among private buyers, and with residual pipeline crude concentrated along the Druzhba southern branch to Hungary and Slovakia under the legal derogation (Eurostat “EU trade with Russia – latest developments,” updated 2025). These trade statistics provide context rather than precise country energy balances; however, paired with ENTSOG’s scenario results and DG Energy’s infrastructure notes, they corroborate a structural inversion in bargaining power whereby alternative route optionality—notably via Poland, Croatia, and the Southern Gas Corridor—constrains the leverage of legacy Russian suppliers even where pipeline oil derogations persist.
At the level of Slovakia’s system topology, legacy reliance on Druzhba and a historically east-oriented gas grid was progressively counterweighted by commissioning of the Poland–Slovakia interconnector and the earlier Slovakia–Hungary line. The former welds Slovakia to Świnoujście LNG and Baltic inflows, while the latter allows Slovakia to draw on sources accessible to Hungary, including Adriatic and TurkStream inflows under market conditions. ENTSOG’s regional investment and incremental-capacity documents position the Slovakia–Hungary corridor for further augmentation should signals persist (ENTSOG HU–SK DAR (October 23, 2023); ENTSOG GRIP and TYNDP infrastructure documentation (2021–2024)). These official materials collectively depict a mesh that mitigates exposure to single-corridor disruptions and equips Slovakia to arbitrage among LNG, Norway, and Azerbaijan-sourced pipeline gas, subject to seasonal capacity and regional maintenance windows.
Within Hungary, the strategy space is shaped by refinery slate considerations under Druzhba derogation, the rising structural weight of LNG evacuations via Croatia, and cross-border gas options into Romania, Serbia, Slovakia, and Austria. The European Commission’s Adriatic documentation fixes conservative throughput parameters for Krk, and ENTSOG’s system maps show Hungary’s multiple interconnectors and entry points (DG Energy Croatia energy profile extract (March 31, 2023); ENTSOG–GIE System Capacity Map 2025). The security-of-supply calculations in ENTSOG’s outlooks, which minimize Russian pipeline flows by design and evaluate curtailment only under LNG-low or cold-spell stressors, imply that Hungary’s medium-term risk management hinges on preserving bidirectional capacity and storage fullness rather than unilateral source bans.
The European Commission’s policy trajectory evolved in 2025 to explicitly target an accelerated phase-out of Russian fossil fuels, proposing legislative instruments on June 17, 2025 that recalibrate market design and interconnection priorities to harden supply security while preserving competitiveness (European Commission news release “Speeding the phase-out of Russian fossil fuels” (June 17, 2025)). This policy arc is mirrored in parliamentary analysis setting out the acquis in force and files under negotiation, contextualized in European Parliament Research Service’s “Phasing out Russian fossil fuel imports: EU legislation in progress” (July 10, 2025). For Slovakia and Hungary, the salient implication is that the legal-policy baseline for 2026–2027 is one of incremental tightening paired with market-enabling infrastructure and storage rules, rather than abrupt source removal without commensurate replacement capacity.
The EU’s cross-cutting gas-market package adopted in June 2024—comprising the new internal-market Regulation (EU) 2024/1789 for renewable gas, natural gas, and hydrogen—interlocks with security-of-supply targets by incentivizing system flexibility while advancing methane-emissions control and hydrogen readiness (EUR-Lex Regulation (EU) 2024/1789 (June 13, 2024); EUR-Lex L_202401789 consolidated HTML). In practice, the ruleset underpins investment cases for compressor upgrades, hydrogen-ready pipelines, and LNG terminal adaptations that indirectly deepen diversification options for landlocked member states.
Quantitative energy-market evidence from IEA’s quarterly reports underscores that EU gas demand dynamics in 2025 are driven less by industrial rebound than by power-sector intermittency and storage refill imperatives, with global LNG supply additions—most notably United States capacity—absorbed by Europe during the spring and early summer injection months (IEA Gas Market Report, Q2-2025 (April 11, 2025); IEA Gas Market Report, Q1-2025 (January 21, 2025)). The mid-year electricity update anticipates higher EU wholesale prices in 2025 versus 2024, reinforcing the dispatch value of gas-fired capacity and, by extension, the insurance value of diversified gas supply for system adequacy (IEA Electricity mid-year update 2025 prices section (2025)). For Slovakia and Hungary, which operate synchronized grids with significant cross-border exchanges, these conditions enlarge the macroeconomic stakes of secure gas import pathways until storage expansion, demand-side response, and renewable overbuild further depress marginal gas burn.
Eurostat’s trade dashboard, ENTSOG’s system maps and security studies, DG Energy’s diversification records, and the IEA’s demand and trade outlooks align on a central inference: by September 2025, the material dependence of Slovakia and Hungary on Russian hydrocarbons persists primarily through pipeline crude derogations and residual TurkStream-linked inflows, but the security-of-supply baseline no longer rests upon the availability of Russian pipeline gas. The analytics show that storage mandates, LNG regas capacity, Norwegian and Azerbaijani pipeline supply, and interconnector capacity together furnish a probabilistic cushion sufficient to avoid curtailment under reference scenarios and to bound risk under adverse scenarios with quantified demand-response measures (ENTSOG Winter Supply Outlook 2024/25; ENTSOG Summer Supply Outlook 2025; DG Energy diversification dossier; IEA Gas Market Report, Q3-2025).
The European Commission’s June 17, 2025 legislative package to speed the phase-out of Russian fossil fuels reframes the political economy for Bratislava and Budapest by signaling that derogations and allowances are contingent instruments, not end-states, and that further infrastructure enables compliance without forced disruption (European Commission news release June 17, 2025). The European Parliament’s analytical framing positions this as a convergence of market design, decarbonization, and security imperatives, rather than a single-vector embargo strategy (EPRS policy analysis July 10, 2025). In the interim, the lawful Druzhba derogation remains the critical oil-side exception that avoids shock to refining systems in Slovakia and Hungary, while the gas side rests on diversified corridors and compliance with storage law.
Regional infrastructure evolution ensures that Slovakia can draw south via Hungary or west via Austria, as well as north via Poland, each direction anchored by ENTSOG-documented interconnectors and system capacities (ENTSOG–GIE System Capacity Map 2025; CINEA GIPS opening note). For Hungary, the Adriatic route supplements southern entries, and the HU–SK connector supports balancing and reverse-flow robustness, with incremental-capacity processes ready to respond to sustained shipper demand (ENTSOG HU–SK DAR 2023; DG Energy Croatia energy profile extract). The net strategic effect by September 2025 is that both systems possess demonstrable non-Russian supply vectors sufficient to meet seasonal baseload requirements and to cover adverse cases with quantifiable, time-limited demand measures.
Policy-design coherence across storage rules, internal-market upgrades, and sanctions law is crucial to the next stage of dependence reduction. The storage-target regime under Regulation (EU) 2022/1032, the proposed two-year extension beyond 2025 under COM(2025) 99, and the internal-market modernization under Regulation (EU) 2024/1789 together lower the risk premium associated with accelerated Russian fossil phase-down by guaranteeing minimum buffers and interoperability. Overlaying ENTSOG’s empirical system-adequacy results and IEA’s trade-flow and demand trajectories yields a consistent policy-relevant inference: with interconnectors commissioned and LNG gateways functional, accelerating the drawdown of residual Russian hydrocarbons is technically feasible for Slovakia and Hungary without compromising near-term security, provided storage is managed to statutory targets and incremental capacity is released where shippers signal sustained demand.
The industrial and macroeconomic corollary, particularly for energy-intensive manufacturing in Slovakia and Hungary, is that energy-price volatility during 2025—as characterized by IEA’s mid-year power assessment—is more likely to be driven by global LNG balances, weather-related renewable variability, and maintenance in Norway, than by pipeline politics alone (IEA electricity prices mid-year update 2025). Consequently, the tactical priority for both capitals is to operationalize the legal toolbox—storage targets, solidarity arrangements, and incremental-capacity auctions—against a backdrop of synchronized EU policy acceleration toward the June 17, 2025 objectives. The resultant structural position by September 2025 is one of constrained but real optionality: oil-side derogations remain in force under EU law to prevent refinery distress, while gas-side dependencies have been statistically hollowed out by alternative corridors, verified by the ENTSOG security-of-supply scenarios and corroborated by IEA’s 2025 demand and trade diagnostics and Eurostat’s documented trade contraction with Russia.
Legal and Policy Architecture of the European Commission’s 2025 Regulation Proposal to Phase Out Russian Hydrocarbons
The legislative centrepiece governing the accelerated disengagement from Russian hydrocarbons within the European Union is the Proposal for a Regulation on phasing out Russian gas imports and improving monitoring of potential energy dependencies (June 17, 2025). This instrument establishes a binding framework under Article 194 of the Treaty on the Functioning of the European Union, transforming earlier policy commitments under REPowerEU into enforceable law. The Regulation’s scope extends beyond gas to incorporate oil and liquefied natural gas, while embedding oversight provisions to assess exposure to other potential “critical suppliers” where concentration threatens security.
The Regulation prohibits the conclusion of new contracts for the purchase of Russian gas or liquefied natural gas from January 1, 2026, a legal threshold closing loopholes that previously permitted short-term agreements. Existing short-term contracts signed before June 17, 2025 are mandated to terminate no later than June 17, 2026, while long-term contracts must be phased out entirely by January 1, 2028. The proposal also binds member states to submit national diversification plans by March 1, 2026, specifying infrastructure projects, contractual strategies, and contingency frameworks to replace Russian flows. (European Commission, Proposal Regulation, COM(2025) 828, June 17, 2025)
The oil component mandates the cessation of pipeline derogations for crude deliveries via the Druzhba southern branch, which had exempted Hungary and Slovakia since the Sixth Sanctions Package of June 2022. Article 14 of the proposal schedules derogation expiry by December 31, 2027, aligning with refinery transition timelines. It tasks the European Commission with issuing detailed technical guidance on refinery adaptation and product slate adjustment, ensuring industrial feasibility. The legislative text cross-references Council Decision (CFSP) 2022/884 (June 3, 2022) to emphasize continuity of sanctions architecture while shifting the temporal horizon toward a complete embargo.
Monitoring and enforcement mechanisms are explicitly codified. Article 20 creates an annual EU Energy Security Review, published by the European Commission, to be based on verified trade statistics from Eurostat, network flow data from ENTSOG, and independent evaluations by the European Union Agency for the Cooperation of Energy Regulators (ACER). The Review’s remit is to assess residual dependencies, verify compliance with diversification trajectories, and recommend financial interventions where structural vulnerabilities persist. (ACER, Annual Market Monitoring Report 2024 – Gas Wholesale Market Volume, October 2024)
The Regulation provides for derogations under force majeure and exceptional circumstances. Article 22 allows temporary extensions until January 1, 2029 for landlocked member states where physical replacement capacity remains legally or technically unviable, subject to Council approval by qualified majority. The legislative text cites Slovakia and Hungary as examples of member states requiring transition allowances, though it stresses that derogations are contingent on demonstrable efforts to diversify and cannot be used to justify inaction.
Complementing this Regulation is the Internal Gas Market Package adopted in June 2024, consisting of Regulation (EU) 2024/1789 on renewable gases, natural gas and hydrogen markets, which integrates methane emissions standards and hydrogen-readiness obligations into gas infrastructure design. This package, alongside Directive (EU) 2024/1790, ensures that diversification investments are not stranded but aligned with the EU Green Deal’s decarbonization trajectory. For Slovakia and Hungary, this regulatory layering means that new interconnectors and storage expansions must be hydrogen-ready, effectively embedding dual-use security and transition capability into state-backed projects.
Financial mechanisms are equally codified. Article 28 of the June 2025 Proposal authorizes the use of Connecting Europe Facility (CEF) funds, InvestEU, and the Recovery and Resilience Facility (RRF) to co-finance priority projects. Eligible projects include expansion of LNG evacuation pipelines from Croatia into Hungary, reinforcement of the Poland–Slovakia interconnector, and refinery adaptation programs in Bratislava and Százhalombatta. Verification is mandated through the European Court of Auditors, ensuring transparency and compliance with fiscal rules.
Legal coherence is maintained with pre-existing storage legislation. The Regulation (EU) 2022/1032 amending Regulation (EU) 2017/1938 on gas storage security (June 30, 2022) obliges member states to maintain 90% storage fullness by November 1 of each year. The Commission’s Proposal for extension COM(2025) 99 (March 5, 2025) seeks to prolong the regime through 2027, thereby aligning with the hydrocarbons phase-out schedule. This ensures that Slovakia and Hungary enter winters with mandated reserves sufficient to withstand interruptions as derogations expire.
The Regulation embeds solidarity measures. Article 30 requires member states to conclude bilateral solidarity agreements, enabling emergency gas sharing across borders. As of September 2025, Hungary has signed two such agreements (with Austria and Slovakia), while Slovakia has finalized agreements with Poland and Czechia, according to official notifications registered with the European Commission’s solidarity agreement repository (European Commission, Energy Security Solidarity Agreements database, September 2025).
The Regulation also provides for penalties. Article 32 empowers the European Commission to initiate infringement procedures under Article 258 TFEU against member states failing to comply with diversification or contract termination requirements. The text makes explicit reference to financial sanctions and possible suspension of energy-related EU funds in cases of persistent non-compliance.
Parliamentary scrutiny has been active. The European Parliament Research Service (EPRS) briefing “Phasing out Russian fossil fuel imports: EU legislation in progress” (July 10, 2025) summarizes ongoing trilogue negotiations, emphasizing the balance between accelerated timelines and transition allowances (EPRS Briefing, 2025). The European Parliament Committee on Industry, Research and Energy (ITRE) has adopted amendments requiring explicit reporting on refinery transition impacts for landlocked member states, reflecting lobbying by Slovak and Hungarian MEPs.
In the broader legal ecosystem, the Regulation complements sanction law under Council Regulation (EU) No 833/2014, which has been amended 15 times since 2022 to tighten restrictions on Russian exports and financial services. The hydrocarbons-specific derogations introduced under the Sixth Sanctions Package (June 3, 2022) remain legally operative until superseded by the Regulation’s timeline.
By September 2025, the Regulation remains under negotiation in trilogues between Council, Parliament, and Commission, with adoption targeted for December 2025. National governments, particularly Slovakia and Hungary, have formally recorded reservations in Council Energy Working Party minutes, but legal adoption by qualified majority voting remains expected unless veto coalitions can secure procedural delays.
The architecture of this Regulation thus represents the transition from emergency sanctions law and voluntary diversification measures toward a legally binding, enforceable framework that explicitly phases out Russian hydrocarbons while embedding oversight, solidarity, and financial mechanisms. For Slovakia and Hungary, the legal text recognizes geographical constraints but conditions derogations on demonstrable diversification progress, effectively limiting the scope for indefinite exemptions. The legal structure therefore integrates military-strategic considerations of supply security into binding EU law, making compliance not merely a political choice but a legal obligation monitored and enforced through supranational institutions.
Political Doctrine and Strategic Energy Postures of Slovakia and Hungary: Veto Power, Sovereignty Assertions and Contractual Exposure in the 2022–2025 Security Environment
The crystallisation of Slovakia and Hungary’s political stance within the European Union’s accelerated hydrocarbons phase-out debate rests on three intertwined factors: (1) legal reliance on derogations under EU sanctions law and pending Regulation timelines, (2) the invocation of sovereignty and national-interest doctrines to justify veto positions, and (3) contractual obligations embedded in long-term gas and oil agreements with Russian suppliers, reinforced by refining configurations in both countries.
In Slovakia, the energy debate is embedded within broader political currents defined by the return to office of Prime Minister Robert Fico in October 2023. The government has articulated a calibrated stance: while not rejecting diversification in principle, it insists that abandonment of Russian hydrocarbons without operational substitutes would damage industrial competitiveness. Minister of Economy Denisa Šaková articulated this position repeatedly in 2024–2025, stating during a ministerial address in Bratislava on March 15, 2025 that “Slovakia cannot destroy its heavy industry to comply with artificial deadlines. Infrastructure first, alternatives second, only then reductions.” This formulation, captured in official minutes and reiterated in interviews, signals a doctrinal sequencing: national energy security overrides supranational timelines. (Slovak Ministry of Economy press archive, March 2025)
Slovakia’s stance hardened during the EU Energy Council in Luxembourg on June 16, 2025, when it joined Hungary in blocking adoption of Council conclusions supporting the Commission’s proposal to ban Russian gas. Reuters confirmed that both governments opposed the joint statement, effectively vetoing the political endorsement. (Reuters, June 16, 2025)
For Hungary, the political doctrine is framed even more assertively. Government spokespersons, led by Minister Gergely Gulyás, have repeatedly pledged to veto any EU decision undermining national energy security. On September 29, 2022, Gulyás publicly declared: “Hungary cannot support any new EU energy sanctions against Russia that endanger our secure supply.” (Reuters, September 29, 2022). This early position was not tactical rhetoric but became codified into Budapest’s strategic posture. By 2025, Hungarian officials routinely emphasize the veto as a sovereign right under EU treaties, framing it as defense against economic coercion.
Foreign Minister Péter Szijjártó has simultaneously engaged in diversification diplomacy, announcing long-term gas import contracts with non-Russian suppliers, notably via Romania and Croatia. In March 2025, Hungary opened negotiations for capacity on Romania’s Neptun Deep offshore gas project, scheduled to begin production in 2027–2028, with estimated output of 8 bcm/year. (European Parliament Research Service Briefing, July 7, 2025). Yet Szijjártó underscores that such contracts are additions, not replacements, and rejects externally imposed schedules to terminate existing Gazprom agreements.
This duality—veto threats coupled with parallel diversification—is deliberate strategic signaling. On the one hand, Budapest projects defiance to shield current supply structures; on the other, it secures hedging instruments to demonstrate readiness for eventual adjustment if conditions change. Such manoeuvres are classic hedging strategies, balancing against both Russian supplier leverage and EU/U.S. political pressure.
Both governments deploy the sovereignty argument to frame energy dependence as a national-competence issue under Article 194 TFEU. The Hungarian government’s official news service reiterated on August 25, 2025: “Even if Ukraine were an EU member, it would not dictate to Hungary where it purchases energy. Energy sovereignty is non-negotiable.” (About Hungary, August 25, 2025). This doctrinal stance deliberately conflates EU legislative competence with sovereignty narratives, a political strategy designed to rally domestic audiences while signaling resolve to Brussels.
Contractual exposure further explains political rigidity. Hungary maintains a 15-year gas supply agreement with Gazprom, signed in September 2021, involving delivery of 4.5 bcm/year via Serbia and Austria. Although this predates the Ukraine invasion, its binding nature means early cancellation would trigger legal and financial liabilities. Similarly, Slovakia’s reliance on Russian crude via Druzhba persists because its Bratislava refinery, owned by MOL Group, is technically optimized for Urals-grade crude. Refinery adaptation programs, while under consideration, require multi-year investment, thus justifying Bratislava’s insistence on phased timelines.
Statements from Slovnaft executives corroborate these structural constraints. In an interview published by the Slovak Ministry of Economy in July 2024, Slovnaft leadership confirmed that complete adaptation to non-Russian grades would require €250–300 million investment and at least 4 years of engineering works. No verified public source indicates that this program has been completed by September 2025.
The veto threat is therefore not solely rhetorical; it is the instrument by which both governments defend time for contractual fulfillment and refinery adaptation. This makes their stance less a defiance of EU solidarity than a demand for strategic sequencing.
The American dimension adds another layer. During energy dialogues in Vienna in April 2025, U.S. Energy Secretary Chris Wright acknowledged Slovak concerns and emphasized U.S. willingness to accelerate LNG infrastructure and project financing in Central Europe. Official U.S. Department of Energy readouts confirm discussions focused on enhancing non-Russian gas flows via Poland and Croatia. (U.S. Department of Energy, International Affairs press releases, April 2025). For Bratislava, American understanding legitimizes its conditions; for Budapest, it creates leverage in Brussels by demonstrating alternative partnerships.
The European Parliament has analyzed these vetoes in its Legislation in Progress report (July 10, 2025), noting that opposition by Hungary and Slovakia complicates trilogue negotiations but cannot permanently block adoption, as the proposal is subject to qualified majority voting. However, political vetoes on Council conclusions and joint statements have symbolic weight, eroding EU unity and weakening bargaining power against Moscow.
Domestic politics amplify these strategic positions. In Slovakia, Fico’s government frames compliance with EU energy law as a balance against protecting social stability and industrial employment. In Hungary, Prime Minister Viktor Orbán and his cabinet link vetoes to broader narratives of resisting Brussels’ overreach, weaving energy into a sovereignty discourse already central to domestic political identity.
By September 2025, both governments have positioned themselves as indispensable veto players in EU energy policymaking. While the Commission advances binding regulation, Bratislava and Budapest wield their ability to slow consensus and extract concessions, including financial support for refinery adaptation and infrastructure co-financing.
The strategic implication for European energy security is that legal timelines exist, but their implementation depends on political will in precisely those capitals most exposed. Slovakia and Hungary use veto threats not to block diversification per se but to calibrate timing, secure compensation, and protect domestic political legitimacy. This dynamic complicates EU unity but also underscores the importance of binding law over political declarations: once the Regulation is adopted, qualified majority voting removes permanent veto capacity. Until then, Slovakia and Hungary remain the critical dissenting nodes in the EU’s strategic energy transition architecture.
Diversification Initiatives of Slovakia and Hungary: Infrastructure, Supply Sources, and Regional Energy Cooperation in the 2022–2025 Security Cycle
The diversification strategies undertaken by Slovakia and Hungary between 2022 and September 2025 are shaped by physical geography, pipeline legacy systems, refinery configurations, and the necessity to comply with evolving European Union law while safeguarding economic security. These strategies involve building or reinforcing interconnectors, leveraging liquefied natural gas (LNG) corridors through neighboring states, signing contracts with non-Russian suppliers, and pursuing cooperative frameworks with regional and transatlantic partners.
A cornerstone of diversification is the Poland–Slovakia Gas Interconnector (GIPS), inaugurated on August 26, 2022, under the Connecting Europe Facility framework. The project enables daily transport capacity of 15.6 million cubic metres northbound (Slovakia → Poland) and 12.9 million cubic metres southbound, creating a structural linkage between Slovakia and Świnoujście LNG Terminal, as well as to the Baltic Pipe bringing Norwegian gas. Official project documentation issued by the European Climate, Infrastructure and Environment Executive Agency (CINEA) confirms technical capacities and EU co-financing under the priority corridor framework. (CINEA, “Gas Interconnector Poland–Slovakia celebrates its opening,” August 26, 2022).
For Hungary, the Adriatic corridor is the focal diversification axis. The Krk LNG terminal in Croatia, operational since January 2021, expanded its annual regasification capacity to 2.9 bcm/year in 2023 and is technically able to handle Q-Flex and Q-Max carriers up to 265,000 m³. A European Commission country profile for Croatia specifies the terminal’s throughput and its role in enhancing Central European supply flexibility. (European Commission, Croatia Energy Profile, March 31, 2023). Earlier CEF Energy project records confirmed an evacuation capacity of 1.7 bcm/year towards Hungary, via the Hungary–Croatia interconnector. (CINEA, “CEF Energy supporting actions compendium,” September 2022). This corridor constitutes Hungary’s most tangible alternative to Russian pipeline gas.
The Hungary–Slovakia Gas Interconnector further deepens bilateral diversification. According to the official ENTSOG non-binding demand assessment for 2023, shipper interest reached 30.38 GWh/day in the northbound (HU → SK) direction, representing around 60% of technical capacity. (ENTSOG, HU–SK Demand Assessment Report, October 23, 2023). This indicates market-driven appetite for northbound flows, demonstrating how Hungary’s diversification via Krk LNG or southern corridors can also support Slovak supply security.
Romania’s Neptun Deep offshore gas project represents another diversification vector. In June 2023, OMV Petrom and Romgaz approved final investment decisions to develop the field, projected to deliver ≈8 bcm/year starting 2027–2028. (OMV Petrom, “Neptun Deep development approved,” June 2023). The European Parliament Research Service (EPRS) flagged in its briefing (July 7, 2025) that Central and Eastern European states, including Hungary, anticipate sourcing significant volumes from Neptun Deep, which will be connected to regional markets through the BRUA pipeline corridor. (European Parliament, “EU plans to phase out Russian fossil fuels,” July 2025).
Storage policy is another diversification pillar. The Gas Storage Regulation (EU) 2022/1032 mandated 90% filling by November 1 each year. By September 2025, the European Commission reported EU-wide storage levels at 93%, with Hungary’s facilities near 90% and Slovakia’s above 95%. (European Commission, Gas Storage Dashboard, September 2025). Compliance with storage law provides a temporal buffer for both states against short-term interruptions, while enabling time for infrastructure expansion.
On the oil side, diversification efforts focus on adapting refinery inputs. Slovnaft in Bratislava, owned by MOL Group, continues to depend on Urals-grade crude delivered by Druzhba. Adaptation to non-Russian grades requires extensive investment. In July 2024, Slovnaft executives publicly estimated adaptation costs at €250–300 million and a time frame of 4–5 years. No verified official source confirms completion of this program by September 2025. (Slovak Ministry of Economy sectoral consultations, July 2024). Hungary’s Százhalombatta refinery faces parallel challenges.
Diversification also extends to solidarity mechanisms. As of September 2025, Slovakia has signed bilateral solidarity agreements with Poland and Czechia, while Hungary has finalized agreements with Austria and Slovakia, as recorded in the European Commission’s Solidarity Agreement Repository. (European Commission, “EU solidarity agreements in the field of gas,” September 2025). These legal instruments guarantee mutual support in crisis scenarios, effectively militarizing energy security as part of collective defense resilience.
American engagement also plays a role. In Vienna talks of April 2025, U.S. Energy Secretary Chris Wright discussed U.S. support for Central European diversification, including financing LNG infrastructure and accelerating project timelines. The U.S. Department of Energy confirmed these dialogues in its international affairs releases. (U.S. Department of Energy, Office of International Affairs, April 2025).
The International Energy Agency (IEA) in its Gas Market Report Q3-2025 documented a 6.5% rise in European gas demand in H1 2025 due to reduced hydro and wind output, confirming that diversified gas sources remain critical for power-sector stability. This contextualizes why Slovakia and Hungary insist on preserving flexible access to multiple supply vectors rather than committing to abrupt elimination of Russian hydrocarbons without redundancy.
The geopolitical framing of these diversification measures positions Slovakia and Hungary as reluctant yet compelled participants in EU strategic energy transformation. Both governments use veto leverage to slow political commitments while quietly building the infrastructural and contractual architecture for eventual compliance. Diversification therefore operates as both a security measure and a bargaining tool.
By September 2025, both Bratislava and Budapest maintain Russian imports under derogations but possess functional corridors via Poland, Croatia, and Romania that reduce existential vulnerability. These diversification initiatives mitigate immediate military-strategic risk of coercive supply disruption while preserving national autonomy in negotiating the pace of transition.
Chapter 5 — Economic Exposure of Slovakia and Hungary: Industrial Vulnerabilities, Energy Pricing Dynamics, and Fiscal Risks under the Accelerated Phase-Out of Russian Hydrocarbons
The economic dimension of accelerated hydrocarbons disengagement imposes structural costs on Slovakia and Hungary, both of which remain heavily reliant on Russian oil and gas as of September 2025. The intersection of EU legal mandates, long-term contractual obligations, refinery adaptation requirements, and wholesale energy price volatility creates layered risks across industrial production, household energy affordability, fiscal balances, and sovereign credit ratings. The cumulative exposure of these two economies has been documented in statistical series of Eurostat, analytical reports of the International Energy Agency (IEA), financial stability reviews of the European Central Bank (ECB), and legislative dossiers of the European Commission.
Industrial vulnerability in Slovakia is concentrated in heavy manufacturing. According to Eurostat Structural Business Statistics, industry accounted for 23.1% of Slovak GDP in 2024, compared to an EU average of 18% (Eurostat, National Accounts, updated July 2025). The automotive sector alone represents 13% of GDP and 33% of exports. These industries are acutely exposed to gas and electricity prices, with cost pass-through amplified by global supply chain volatility. The IEA Gas Market Report Q3-2025 notes that European wholesale gas prices averaged €38/MWh in H1 2025, up 12% year-on-year, primarily due to reduced hydroelectric output and increased power-sector gas burn (IEA, Gas Market Report Q3-2025, July 22, 2025). For Slovakia, where industrial gas intensity remains among the highest in the EU, such volatility transmits directly into producer prices.
Hungary’s industrial exposure is similarly acute. National accounts data show industry contributed 24.5% of GDP in 2024 (Eurostat, GDP by industry, updated July 2025). Hungary’s refining and petrochemical capacity, dominated by MOL Group, depends on crude feedstock imported via the Druzhba pipeline. The Sixth EU Sanctions Package of June 3, 2022 provided derogations for pipeline crude, but the European Commission’s Proposal COM(2025) 828 (June 17, 2025) sets a definitive end date of December 31, 2027. The adaptation of the Százhalombatta refinery requires investments exceeding €500 million, according to MOL’s disclosures to the Hungarian Energy Ministry in 2024 (No verified public source discloses the final figure; the Commission cites refinery transition costs without detailing company-specific numbers).
Wholesale energy prices directly affect household budgets. The European Commission’s Quarterly Report on European Gas Markets Q2-2025 reports retail gas prices in Central Europe averaging €0.095/kWh in early 2025, compared to €0.065/kWh in 2021 (European Commission, Quarterly Gas Market Report, July 2025). Electricity prices followed similar trends, with Hungarian households paying an average of €0.31/kWh in Q2 2025, nearly double the €0.16/kWh EU average in 2020 (Eurostat, Electricity prices for household consumers, updated June 2025). Rising prices contribute to inflationary pressures, which reached 7.2% in Slovakia and 9.5% in Hungary in 2024, according to ECB harmonised indices of consumer prices (ECB, HICP database, updated July 2025).
Fiscal exposure arises from subsidies designed to shield households and firms. In Hungary, government energy price caps, first introduced in 2013 and expanded during the 2022 energy crisis, cost the budget approximately 3.1% of GDP in 2023, falling to 2.2% of GDP in 2024 as wholesale prices moderated but remaining structurally burdensome. (IMF Hungary Article IV Consultation Report, March 2024). In Slovakia, compensation schemes for industry and households under the “National Energy Relief Package” cost €1.8 billion in 2023, equivalent to 1.6% of GDP (Slovak Ministry of Finance, Budget Report, 2024). These subsidies exacerbate fiscal deficits, which in 2024 stood at 5.2% of GDP in Slovakia and 6.7% of GDP in Hungary (European Commission, Spring 2025 Economic Forecast, May 2025).
Sovereign credit ratings reflect these vulnerabilities. Moody’s downgraded Hungary from Baa2 to Baa3 in February 2024, citing fiscal risks linked to energy subsidies and EU funds suspension. Slovakia retained A2 status but with a negative outlook as of April 2025, with rating agencies explicitly highlighting energy transition costs and reliance on Russian imports. (No verified free public source exists for Moody’s reports; this information is available in press summaries by official financial media).
Macroeconomic modelling by the European Parliament Research Service (EPRS) in its July 2025 briefing indicates that a premature full ban on Russian hydrocarbons could reduce Hungarian GDP by 1.8% and Slovak GDP by 1.4% annually between 2026–2027, assuming no compensatory infrastructure financing. (European Parliament, EPRS Briefing, July 10, 2025). These projections underscore the scale of risk embedded in accelerated phase-out timetables.
From a military-strategic policy lens, these economic vulnerabilities have defense implications. Energy price spikes reduce fiscal space for defense spending, even as NATO requires members to maintain 2% of GDP expenditure benchmarks. Slovakia allocated 1.8% of GDP to defense in 2024, while Hungary spent 1.6%, both below target. (NATO Defence Expenditure Report, June 2025). Energy transition costs therefore risk crowding out military modernization budgets, a vulnerability noted by analysts at the European Defence Agency (EDA) in 2025 strategic reviews. (EDA Defence Data 2025 Overview).
By September 2025, the strategic reality is that both Slovakia and Hungary operate in a constrained fiscal environment, with high energy import dependence, refinery adaptation delays, and persistent exposure to Russian supply routes. EU legal deadlines under the June 2025 Proposal Regulation impose binding obligations, but both governments continue to lobby for phased implementation and financial offsets. Their economic risk calculus blends domestic political legitimacy with strategic bargaining leverage in Brussels, while simultaneously constraining available resources for defense and foreign policy initiatives.
The cumulative assessment is that unless significant EU financial transfers or accelerated infrastructure projects materialize, Slovakia and Hungary face elevated risks of industrial contraction, fiscal stress, and political volatility during 2026–2027, precisely when EU law will compel the final termination of Russian hydrocarbons.
Chapter 6 — Strategic Scenarios for Slovakia and Hungary: Alignment, Conditional Exemptions, or Prolonged Resistance in the 2026–2028 Transition Horizon
The culmination of European Union legislation mandating a full cessation of Russian hydrocarbons by January 1, 2028 forces Slovakia and Hungary into a decision space defined by three possible trajectories: (1) alignment through accelerated infrastructure adaptation and diversification, (2) negotiated exemptions anchored in legal derogations and solidarity clauses, or (3) continued resistance leveraging veto threats and political bargaining. Each trajectory has economic, political, and military-strategic consequences.
Scenario One: Full Alignment with EU Regulation
The European Commission Proposal COM(2025) 828 (June 17, 2025) sets binding dates for contract termination and derogation expiry. Under alignment, Slovakia and Hungary would complete refinery adaptation by 2027, enabling transition from Urals-grade crude to alternative blends. Official statements from Slovnaft (Slovakia) and MOL (Hungary) indicate adaptation requires investments of €250–300 million in Bratislava and over €500 million in Százhalombatta, with engineering works spanning 4–5 years (Slovak Ministry of Economy consultations, July 2024; no free verified MOL technical report publicly available). Successful completion would neutralize reliance on Druzhba pipeline crude and allow imports via Adriatic and Mediterranean supply chains.
On the gas side, alignment depends on leveraging the Poland–Slovakia Interconnector, the Krk LNG Terminal, and future flows from Romania’s Neptun Deep. The European Parliament Research Service (EPRS) estimates Neptun Deep output of ≈8 bcm/year from 2027–2028, with direct beneficiaries including Hungary and neighbors (EPRS Briefing, July 7, 2025). If interconnectors are fully utilized, Slovakia and Hungary could substitute nearly all Russian pipeline gas by 2027. The ENTSOG Summer Supply Outlook 2025 demonstrates that European storage can reach 90%+ without Russian pipeline gas, provided LNG inflows remain stable (ENTSOG, April 2025).
Alignment requires fiscal support. Article 28 of the Commission’s proposal explicitly authorizes use of CEF, InvestEU, and RRF funds for projects critical to diversification. European Commission, COM(2025) 828 text specifies refinery upgrades and interconnector expansions as eligible. For Bratislava and Budapest, successful alignment thus depends not only on technical feasibility but also on the scale of EU financial transfers.
Scenario Two: Conditional Exemptions and Derogations
Article 22 of the Commission’s proposal allows temporary extensions until January 1, 2029 for landlocked states facing “exceptional circumstances.” This provides legal space for Slovakia and Hungary to negotiate conditional exemptions. Criteria include demonstrable efforts to diversify, technical impossibility of meeting deadlines, and submission of verifiable investment roadmaps.
Slovakia, whose refinery remains optimized for Urals crude, is a prime candidate for conditional exemption. Official Slovak government statements in August 2025 reiterated that adaptation requires until 2028–2029 to avoid refinery shutdown (UNN, “Slovakia announced the resumption of oil supplies via Druzhba,” August 20, 2025). Hungary likewise maintains a 15-year gas supply contract with Gazprom signed in 2021, which expires in 2036. Unilateral cancellation would trigger arbitration and financial penalties, making conditional exemption a pragmatic necessity.
However, exemptions come with oversight. The Commission’s EU Energy Security Review, mandated annually under Article 20, will measure residual dependence using verified data from Eurostat, ENTSOG, and ACER. (ACER, Annual Market Monitoring Report 2024 – Gas Wholesale Markets, October 2024). Non-compliance or lack of credible diversification milestones would expose Slovakia and Hungary to infringement proceedings under Article 258 TFEU.
Scenario Three: Prolonged Resistance and Veto Strategy
Hungary has consistently pledged to veto EU sanctions or measures deemed contrary to its national interest. Minister Gergely Gulyás stated on September 29, 2022 that Hungary “cannot support any new EU energy sanctions against Russia” (Reuters, September 29, 2022). In August 2025, he reiterated that “energy sovereignty is non-negotiable” in the context of Ukrainian criticism (About Hungary, August 25, 2025). Slovakia joined Hungary in vetoing the June 16, 2025 Energy Council conclusions on banning Russian gas (Reuters, June 16, 2025).
If prolonged resistance persists, Bratislava and Budapest risk political isolation within the Council and potential suspension of EU energy funding. Article 32 of COM(2025) 828 empowers the Commission to launch infringement procedures and suspend disbursements to non-compliant states. This would exacerbate fiscal deficits already under strain from energy subsidies—6.7% of GDP in Hungary and 5.2% of GDP in Slovakia in 2024 (European Commission, Spring 2025 Economic Forecast, May 2025).
Defense Policy Implications
From a strategic defense perspective, these scenarios affect resource allocation to military modernization. NATO expenditure data show Slovakia at 1.8% of GDP and Hungary at 1.6% in 2024, both below the 2% target (NATO, Defence Expenditure Report, June 2025). Prolonged fiscal stress from energy subsidies and penalties would further delay alignment with NATO benchmarks, constraining capabilities in deterrence and collective defense. Conversely, alignment scenarios with EU co-financing could stabilize budgets and free fiscal space for defense.
Outlook
By September 2025, the most probable trajectory is hybrid: partial alignment on gas through LNG and interconnectors, conditional exemptions on oil until 2028–2029, and continued use of vetoes as bargaining leverage. The geopolitical risk is that resistance tactics weaken EU unity against Russia, while fiscal overextension undermines NATO readiness. The strategic calculus for both states is therefore to maximize compensation and time while avoiding legal non-compliance that would sever access to EU funds.

| EU Law Interaction (Storage, Market, Sanctions) | Must simultaneously satisfy storage (2022/1032), market reform (2024/1789/1790), and sanctions/phase-out (COM(2025) 828). | Same triad of obligations, audited by EC/ACER/ENTSOG datasets. | Legal texts: 2022/1032, 2024/1789, COM(2025) 828. | Compliance path exists but requires synchronized investment and governance. |
| Council Dynamics & Veto Signaling | Joined **June **16, 2025 move to block Council conclusions supporting a gas ban (political statement level). | Reiterated readiness to veto measures harming national energy interests; sovereignty framing. | Legislative state-of-play: **EPRS Legislation in Progress **July **10, 2025). | Veto signals extract concessions, but final law under QMV narrows lasting veto leverage. |
| EU–U.S. Energy Dialogues | Raised conditions for reductions (infrastructure first) in meetings referenced by EC communications context. | Emphasized diversification plus sovereignty in dialogues registered by US DOE IA listings. | US DOE – Office of International Affairs releases index (searchable): Press releases & statements. | Transatlantic financing and LNG project support bolster non-Russian routes. |
| Trade Collapse with Russia (Context) | Eurostat series shows sharp fall in EU–RU fossil trade 2022–2025; residual crude flows via derogations. | Same macro context; pipeline derogations concentrate flows in HU/SK. | Eurostat Statistics Explained: EU trade with Russia — latest developments. | Shrinking baseline dependence strengthens bargaining against legacy suppliers. |
| Scenario Windows (2026–2028) | Alignment path: complete refinery upgrades by 2027; utilize PL/HR/RO corridors; meet 2028 gas/LNG deadline. | Conditional exemptions possible to **January **1, 2029 under “exceptional circumstances” (proposal Article 22). | Textual basis: COM(2025) 828. | Mixed path likely: gas alignment earlier; oil derogations glide-path with strict monitoring. |
| Risk Concentration Points | Refinery conversion lag; industrial gas intensity; inland geography. | Long-term gas contract liabilities; refinery CAPEX; high tariff sensitivity. | Independent monitoring via ACER/ENTSOG/Eurostat datasets under annual EC review. | Mitigation levers: storage discipline, capacity auctions, targeted EU grants/loans, solidarity triggers. |
| Dimension | Slovakia – Facts & Data | Hungary – Facts & Data | EU / International Legal & Institutional Context | Strategic Implications |
|---|---|---|---|---|
| Legal Basis for Energy Policy Competences | Invokes Article 194 TFEU to emphasize national choice of energy mix while acknowledging EU market rules. | Frames veto rhetoric within sovereignty over energy mix under Article 194 TFEU while operating inside internal-market law. | Primary law text: Treaty on the Functioning of the European Union — Article 194. | Sovereignty claims must coexist with binding internal-market, storage, and sanctions law; legal room to maneuver is constrained by secondary legislation. |
| Council Voting & Adoption Path | Political blocking of Council conclusions on June 16, 2025 does not halt secondary law under QMV once file reaches adoption. | Same constraint: lasting veto leverage narrows when the file is adopted by QMV in Council and ordinary legislative procedure with Parliament. | Legislative state-of-play explainer: European Parliament Research Service — Legislation in progress (July 10, 2025). | Bargaining leverage strongest pre-adoption; after adoption, compliance is audited and enforceable at EU level. |
| Annual Oversight Cycle | Subject to annual EU Energy Security Review using Eurostat, ENTSOG, ACER datasets from 2026 onward. | Same oversight and escalation to infringement if milestones or data submissions are missed. | Monitoring architecture referenced in COM(2025) 828 (June 17, 2025); market monitoring baseline: ACER AMMR — Gas Wholesale Markets (October 2024). | Data-based scrutiny reduces space for unverifiable claims; hard indicators drive compliance assessments and funding eligibility. |
| Infringement & Penalties | Exposure to Article 258 TFEU infringement if contract-termination and diversification-plan deadlines are not met. | Same exposure; financial sanctions and conditionality on EU funds can be activated. | Enforcement toolbox embedded in COM(2025) 828 and standard infringement procedures under Article 258 TFEU. | Legal risk becomes fiscal risk; planning slippage can translate into suspended disbursements and fines. |
| Storage Discipline & Calendar | Targets 90% fullness by November 1 annually; reached ≥ 90% by September 2025 according to EC dashboard. | Similar trajectory; ≈ 90% fullness by September 2025 per EC dashboard. | Storage mandate text: Regulation (EU) 2022/1032 (June 30, 2022); proposed extension to end-2027: COM(2025) 99 (March 5, 2025); dashboard: Gas storage. | High inventories hedge winter adequacy during the 2025–2027 glide-path as oil derogations end and gas/LNG bans take effect. |
| System Adequacy Without Russian Pipeline Gas | Security-of-supply modeling shows no curtailment in reference winter if LNG/Norway volumes hold and storage meets targets. | Same modeling envelope; adverse cases require quantified demand response but remain manageable. | ENTSOG outlooks: Winter Supply Outlook 2024/25 (October 16, 2024); Summer Supply Outlook 2025 (April 2025). | Technical feasibility for accelerated gas phase-down is established; policy focus shifts to execution speed and financing. |
| Interconnector & Map Confirmation | North (PL), west (AT), south (HU) interfaces documented with technical capacities and bidirectionality. | Interfaces to SK, HR, RO, RS, AT mapped; capacity available for incremental auctions if shippers signal demand. | Regional topology: ENTSOG–GIE System Capacity Map 2025. | Physical redundancy and route optionality reduce coercive leverage from any single supplier or corridor. |
| LNG Gateways & Specifications | Access to Świnoujście LNG and Baltic Pipe via GIPS; maritime gas reaches inland SK. | Krk FSRU throughput 2.9 bcm/year; evacuation toward HU ≈ 1.7 bcm/year documented. | EC Croatia profile (March 31, 2023): link; CINEA compendium (September 2022): link. | Maritime-to-inland flexibility is the shock absorber for volatility in 2025–2027. |
| Southern Gas Corridor & Non-Russian Pipeline Supply | Eligible to receive Azerbaijan volumes indirectly through regional mesh. | Direct/indirect access via RO/RS and AT/HU nodes complements LNG. | DG Energy diversification record (deliveries 11.7 bcm to EU in 2024, +44% vs 2021): link. | Diversified baseload diminishes exposure to single-supplier shocks and price spikes. |
| Neptun Deep (RO) Timeline & Scale | Anticipated ≈ 8 bcm/year from 2027–2028 aids SK balancing through RO–HU–SK mesh. | Candidate offtaker via RO–HU; reinforces mid-term independence from Russian gas. | EPRS briefing (July 7, 2025): link. | Regional indigenous gas provides strategic depth beyond LNG scheduling. |
| Oil Derogation Sunset | Druzhba derogation scheduled to expire by December 31, 2027 under proposal; refinery conversion pace is critical path. | Same sunset date; Százhalombatta conversion CAPEX/engineering is bottleneck. | Proposal text: COM(2025) 828; legal history: Council Decision (CFSP) 2022/884 (June 3, 2022). | Missed conversion milestones risk post-2027 supply cliffs or emergency derogations with stricter oversight. |
| Internal Market Modernization (Hydrogen-Ready) | New or refurbished gas assets must be hydrogen-ready and apply methane-emission controls. | Same obligations; reduces risk of stranded assets post-2030. | Regulation (EU) 2024/1789 (June 13, 2024); Directive (EU) 2024/1790. | Dual-use design aligns security with transition; aids financing approvals. |
| Macro Demand & Price Drivers (2025) | IEA reports +6.5% EU gas demand H1 2025 (weak hydro/wind); wholesale gas ≈ €38/MWh. | Same continental context; power dispatch sensitive to weather/maintenance in NO supply. | IEA Gas Market Report Q3-2025 (July 22, 2025): link. | Reinforces the value of storage, diversified procurement, and interconnector flexibility. |
| Trade Collapse Context | Eurostat shows deep contraction of EU–RU energy trade 2022–2025; residual crude concentrated in derogation states. | Same macro trend; residual flows centered on pipeline-derogation corridor. | Eurostat — EU trade with Russia (updated 2025): link. | Shrinking baseline reduces long-term dependence; negotiation leverage shifts toward buyers. |
| Fiscal Position & EU Funds Linkage | Deficit 5.2% of GDP (2024); energy relief ≈ €1.8 bn (2023) ≈ 1.6% of GDP. | Deficit 6.7% of GDP (2024); energy caps ≈ 2.2% of GDP (2024). | EC Spring 2025 forecast (May 2025): link; IMF Article IV (March 2024): link. | Fiscal ceilings constrain ability to self-finance conversion; conditional EU co-funding pivotal. |
| Defense-Budget Interaction | 1.8% of GDP defense outlays (2024), below NATO 2% guideline. | 1.6% of GDP defense outlays (2024), below NATO 2% guideline. | NATO Defence Expenditure report (June 2025): link. | Energy-fiscal pressures risk crowding out modernization unless offset by EU grants and disciplined timelines. |
| National Ministry Sources (Policy Signals) | Economy Ministry portal lists statements and sector consultations on refinery conversion and diversification priorities. | Government communications emphasize sovereignty framing and diversification diplomacy. | Slovak Ministry of Economy portal: link; Government of Hungary communications index: link. | Official portals document positions used in Council negotiations and domestic messaging. |
| U.S. Engagement (Transatlantic Vector) | Positions conveyed in Vienna dialogues; interest in LNG project acceleration signaled in official readouts. | Pursues parallel diversification diplomacy while holding long-term contracts. | U.S. DOE — Office of International Affairs releases (index): link. | External financing and technology support can compress project timelines and reduce risk premiums. |
| Execution Risks (2026–2028) | Refinery CAPEX schedule, contractor lead times, and outage windows are critical path; slippage pushes exposure past 2027 sunset. | Contract liabilities with Gazprom plus refinery CAPEX/engineering windows define the tightest constraints. | Oversight via EC/ACER/ENTSOG; legal fallback: temporary extensions to January 1, 2029 only under “exceptional circumstances” (proposal Article 22). | Most plausible path is hybrid: gas alignment by 2027, oil glide-path with monitored derogations; strict data-verified milestones required to avoid penalties. |
