European energy storage voltage

Why is energy storage important in the EU?

It can also facilitate the electrification of different economic sectors, notably buildings and transport. The main energy storage method in the EU is by far 'pumped hydro' storage, but battery storage projects are rising. A variety of new technologies to store energy are also rapidly developing and becoming increasingly market-competitive.

How much energy storage capacity does the EU need?

These studies point to more than 200 GW and 600 GW of energy storage capacity by 2030 and 2050 respectively (from roughly 60 GW in 2022, mainly in the form of pumped hydro storage). The EU needs a strong, sustainable, and resilient industrial value chain for energy-storage technologies.

What are the benefits of battery energy storage in Europe?

Increasing the use of renewables in the energy mix allows energy imports to be reduced, with clear benefits for Europe’s energy independence and security. The decarbonisation of the energy mix and reductions in overall CO2 emissions are other clear, positive outcomes of an increased use of Battery Energy Storage in Europe.

Can battery energy storage solve Europe's energy challenges?

In order to deploy renewables and to release their potential for ensuring a stable and secure energy supply, Europe needs to work to overcome the intrinsic limits of renewables. One solution to these challenges is Battery Energy Storage.

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.

How can energy storage help the EU develop a low-carbon electricity system?

ENER Working Paper The future role and challenges of Energy StorageEnergy storage will play a ey role in enabling the EU to develop a low-carbon electricity system. Energy storage can supply more flexibility and balan ing to the grid, providing a back-up to intermittent renewable energy. Locally, it can improve the manage
