- EU Plan for Ukraine’s Gas Storage: At a Glance
March 21, 2025
The expiration of the Gazprombank payment exemption for Russian gas transit via Turkish Stream has introduced new uncertainties. As of today, it remains unclear how payments will be processed without violating U.S. sanctions. this situation is further complicated by the suspension of Russian gas transit through ukraine since January 1, after Kiev declined to renew its contract with Gazprom. Consequently, the route through Turkey and Bulgaria remains the primary channel for Russian gas to reach Europe, particularly Serbia, Hungary, and Slovakia.
Sanctions Complicate payment Mechanisms
Gazprombank, the main financial institution for processing Russian gas payments, is under U.S. sanctions, albeit with a temporary exemption previously in place. Earlier this month, a member of parliament questioned the Minister of Energy about payment plans following the exemption’s expiration. The minister stated that existing contracts for capacity reservation do not specify a particular bank for payments.
The mechanism by which Gazprombank operates as the sole licensed institution for these transactions, and whether choice banks can be utilized, remains ambiguous.

According to the Energy Minister, all payments under existing contracts have been fully received by bulgartransgaz EAD.The minister clarified that under capacity reservation contracts, users are responsible for ensuring appropriate payment mechanisms for invoices issued by Bulgartransgaz EAD.
EU Considers Options After Ukraine Transit Halt
The European Union is exploring a plan to leverage Ukraine’s extensive underground gas storage capacity to address tensions between Kiev and Slovakia related to gas transit. Hungary and Slovakia were considerably impacted by the cessation of Russian gas transit through Ukraine. The leaders of both countries have voiced concerns, with threats ranging from blocking sanctions against Russia to halting electricity supply and humanitarian aid to Ukraine. However, these threats have not materialized, and Slovakia has been importing Russian gas via Turkish Stream since February 1.
A proposal, reportedly discussed by European commissioners during a recent visit to Kiev, aims to alleviate Slovakia’s concerns over lost energy transit revenues. Under the agreement, the gas was entering the EU, and Slovakia received transit fees – up to EUR 500 million a year,
according to sources cited by Politico.
Ukraine Eyes Increased Imports and Storage
The European Commission is evaluating a plan to facilitate gas flows to Slovakia without requiring the purchase of Russian gas, aligning with the RePowerEU plan to phase out Russian imports by 2027.The strategy involves Ukraine increasing gas imports from Greece and Turkey, storing up to 10 billion cubic meters.
These supplies would then be transported through Slovak pipelines to countries like Hungary during periods of high demand. This approach is intended to support the objectives of RePowerEU.
The EU is under pressure to resolve the transit issue, with calls for the Commission to find working solutions to the issue of gas transit.
The EU has emphasized the potential of Ukraine’s underground storage facilities, the largest in Europe, capable of storing a meaningful portion of the Union’s total capacity. We will take advantage of the full potential of the huge gas storage facilities of Ukraine, 80% of which are near EU Member States,
said EC leader Ursula von der Leyen during a visit to Kiev.This generates revenue for Ukraine. All these efforts will lead to greater energy security for both Ukraine and the European Union.
This plan also avoids complications associated with Slovakia’s proposal to import gas from Azerbaijan. While Azerbaijan claims it can replace Russian gas flows through ukraine, some experts suggest that Baku might need to rely on Russian gas to meet EU demand.
Bulgaria’s Role: Pros and Cons
Some EU members, such as Finland, view the new plan favorably.

However, logistical challenges may hinder the feasibility of the gas storage plan in Ukraine. Aura Sabadus, a gas market expert at ICIS, noted that while the proposal is beneficial for Ukraine, the Transbalkan pipeline, which runs through Turkey, Bulgaria, Romania, and ukraine, has a limited capacity of approximately 2.5 billion cubic meters, significantly less than the proposed 10 billion cubic meters.
Sabadus attributed this to insufficient capacity in Bulgaria and Romania. Additionally,high transmission fees charged by Romania’s state-owned transgaz discourage gas purchases along this route.
Sergius Macogon, former head of the Ukrainian state operator GTSou, pointed out that Slovakia, Hungary, and neighboring countries already possess adequate gas storage capacity. This raises questions about the added value of utilizing Ukraine’s storage facilities. For me, this idea makes no commercial meaning,
Macogon stated.
Gas traders also express skepticism about the economic viability. One trader noted that while there is interest in purchasing gas from Ukraine, the high costs of transferring gas from Ukraine to Slovakia make it financially impractical, according to Politico.
in practice, EU countries might need to subsidize gas flows to and from Ukraine to make the plan viable.
European Gas Transit: Q&A on Sanctions, Storage, and Shifting Strategies
What are the main challenges facing European gas transit currently?
The European gas market is currently navigating several meaningful challenges:
Sanctions and Payment Uncertainty: The expiration of the Gazprombank payment exemption for Russian gas transit through the Turkish Stream pipeline has created uncertainty about how payments can be processed without violating U.S. sanctions.
Disrupted Transit routes: The suspension of Russian gas transit through Ukraine as January 1, 2025, has shifted reliance to the turkish Stream pipeline, wich goes through Turkey and Bulgaria, creating vulnerability.
How do sanctions impact payments for Russian gas transit?
Gazprombank, the primary financial institution for processing payments for Russian gas, is under U.S. sanctions. While a temporary exemption was in place, its expiration creates ambiguity about the payment mechanisms for future transactions. The question of whether alternative banks can be used remains unanswered.
What is the EU’s plan to leverage Ukraine’s gas storage facilities?
The EU has a plan to:
Utilize ukraine’s Storage: The European Commission is exploring a plan to use Ukraine’s extensive underground gas storage capacity, which is the largest in Europe, to store up to 10 billion cubic meters of gas.
Increase Imports: This involves Ukraine increasing gas imports from Greece and Turkey.
Supply to Member States: The stored gas would then supply countries like Hungary and Slovakia, especially during periods of high demand.
What are the potential benefits of this plan?
the proposed plan offers several potential benefits:
Energy Security: The plan aims to increase energy security for both Ukraine and the EU,which can help the EU phase out Russian gas imports by 2027.
Revenue for Ukraine: ukraine could generate revenue by storing gas for EU member states.
Reduced Reliance on Russian Gas: It potentially reduces reliance on Russian gas and avoids complications from sourcing gas from Azerbaijan.
what are the potential drawbacks and challenges of the plan?
The plan faces several obstacles:
Pipeline Capacity Limitations: The transbalkan pipeline, which runs through turkey, bulgaria, Romania, and Ukraine, has the limited capacity of approximately 2.5 billion cubic meters, which is significantly less than the proposed 10 billion cubic meters.
infrastructure Bottlenecks: Insufficient capacity in Bulgaria and Romania hinders gas flow.
High Transmission Costs: High transmission fees charged by Romania’s state-owned Transgaz discourage gas purchases.
Commercial Viability: Some experts question the commercial viability, as costs for transferring gas from Ukraine may make the plan financially impractical.
* Subsidies May Be Needed: EU countries might need to subsidize gas flows to and from Ukraine.
Are there alternative plans to address gas transit issues?
Yes, Slovakia has proposed importing gas from Azerbaijan.However, some experts have raised concern that Baku might need to rely on Russian gas to meet EU demand.
What role does Bulgaria play in the gas transit plans?
Bulgaria plays a crucial role as the Transbalkan pipeline transits the country, however, its capacity is a limiting factor. Bulgaria’s infrastructure’s limited capacity could hinder the plan.
