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 the penetration rate of solar PV & battery storage systems?

This figure includes both new installations of solar PV + battery storage systems as well as installations of battery storage systems in existing solar PV systems (i.e. retrofits). The penetration rate is still very low in Europe, below one percent. Germany is by far the leading market.

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.

Why should EU countries consider the 'consumer-producer' role of energy storage?

It addresses the most important issues contributing to the broader deployment of energy storage. EU countries should consider the double 'consumer-producer' role of storage by applying the EU electricity regulatory framework and by removing barriers, including avoiding double taxation and facilitating smooth permitting procedures.

Can Europe scale up battery production?

Production in Europe: Battery cell production at scale is dominated by Asia, but European ambitions are far from dead – and moves are afoot to scale up production across the continent. Large-scale storage and solar: Exploring the synergies – tapped and untapped – of collocating large-scale storage with solar power.

Can large-scale storage and solar power work together?

Large-scale storage and solar: Exploring the synergies – tapped and untapped – of collocating large-scale storage with solar power. Expert debate: A panel of respected storage experts gather to share their thoughts on a range of questions and topics concerning the energy storage industry.
