The EU is considering a scheme to supply gas to Ukraine, Moldova, Slovakia and Hungary using Ukrainian underground storage facilities

The option envisages that gas will be pumped into Ukraine's storage facilities so that it can be used in these 4 countries.
According to the RBC-Ukraine's sources, it is about 10 billion cubic metres, 1 billion of which may be for Moldova's needs, and the rest may be distributed among Ukraine, Slovakia, and Hungary. It can be any gas, including American LNG.
It is worth recalling that in 2022 and 2023, the EU discussed the possibility of centralised gas purchases to reduce dependence on Russian energy carriers.
In this case, Ukraine will be able to pay for gas at the expense of the Ukraine Facility programme. This option is being considered.
At the same time, the possibility of lowering transit tariffs in some EU countries, through which gas goes to Hungary and Slovakia, is being discussed. "Europe is very interested in that – such a scheme will remove many of the questions that the Slovakians ask the European Commission about the increase in gas prices after the termination of transit through Ukraine," said a source familiar with the discussion.
At the same time, according to the publication, in the context of preparing a decision on a new gas supply scheme, Ukraine may consider reducing its tariffs, in particular for gas entry/exit to the GTS and for its storage.
With regard to the safety of gas storage in Ukrainian UGS facilities, which are periodically shelled, there is an opinion that if gas is stored there for Hungary and Slovakia, the risks of attacks on UGS facilities will decrease.
As a reminder, Ukraine intends to increase natural gas imports next season, as its production facilities have been hit by Russian drones and missiles. According to Bloomberg, the Government estimates that it will need about 3.5 billion cubic metres of imports to meet domestic demand.
