EU Mobile Energy Storage Container Wind-Resistant

How does energy storage work in the EU?

The main energy storage method in the EU is by far 'pumped storage hydropower', which works by pumping water into reservoirs when there is an electricity surplus in the grid - for example on a sunny or windy day - and releasing it when more energy is needed.

Why should the EU invest in batteries?

It contributes to the EU’s circular economy and zero pollution ambitions and strengthens our strategic autonomy on batteries. Beyond batteries and pumped storage hydropower, the EU ranks second, after the U.S., in the number of companies developing novel energy storage technologies and leads in liquid air energy storage.

What is the European energy storage inventory?

The Commission’s European Energy Storage Inventory can help address this gap within Europe. Launched in March 2025, it is the first European-level tool of its kind, providing a real-time dashboard of energy storage levels in Europe, offering energy storage data across a full range of technologies.

What does the EU's batteries regulation mean for Europe?

The EU’s Batteries Regulation, which entered into force 2 years ago, helps ensure that Europe’s ambition on batteries does not come at an environmental cost. It contributes to the EU’s circular economy and zero pollution ambitions and strengthens our strategic autonomy on batteries.
