Some European countries like Cyprus, Estonia, Finland, Greece, Ireland, Lithuania, Luxembourg, Malta, and Slovenia do not have their own gas storage facilities but rely on solidarity agreements with other countries.

Not all European countries have natural gas storage underground. Smaller or less gas-dependent countries such as Cyprus and Ireland don’t have storage facilities on their land. Instead, they depend on agreements that let them access gas reserves stored in other EU countries. This system ensures they have some energy security even without their own storage.
