Technical FAQs 4

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.

What is the EU Regulation on energy storage?

In brief, the EU regulation in respect of energy storage appears to focus on the following: Public support, strategy, and other policy aspects (for more information on EU state aid to energy projects, see Cross-Border Energy Projects in Times of Crisis: Is EU State Aid a Solution for Green Transition?)

What is the European energy storage inventory?

In March 2025, the Commission launched the European Energy Storage Inventory, a real-time dashboard that displays energy storage levels across different European countries. It is the first European-level tool of its kind and offers energy storage data across a full range of technologies.

What is energy storage Europe Association?

Energy Storage Europe Association is actively shaping the legal and R&D funding framework for energy storage at EU level. Members gain direct influence in the European decision-making process. Members benefit from the Energy Storage Europe Association’s expertise and technical know-how, and they can participate in EU-funded research projects.
