A first project outside the US has been announced by Form Energy, the developer of a novel battery technology promising ‘multi-day’ duration energy storage.

A flurry of BESS project news from big-name players in Western Europe in the run-up to the Energy Storage Summit next week, with Neoen, Statkraft, Zenobē and Infranode moving projects forward in Germany, Ireland, the UK and Denmark. Highlights include a 15-year toll between Drax and Zenobē, and multiple 4-hour duration systems.

New wholesale electricity market rules have been introduced in Ireland, designed to allow battery storage assets to participate directly.

The value of developers and optimisers in the BESS lifecycle, thinking about long-term risk and KPIs for maximising the asset have been key themes at the Battery Asset Management Summit UK & Ireland 2025.

Energy-Storage.news proudly presents our sponsored webinar with GridBeyond, on extracting the maximum value from battery storage assets in Great Britain (GB) and Ireland.

Germany and the UK are currently Europe’s ‘hottest’ markets for battery storage, but others present exciting opportunities, too.

“We need to allow the technology to show us what the most cost effective solution for 10-20-hour duration energy storage is”, managing director of Adaptogen Capital James Mills says.

The Gore Street Energy Storage Fund (GSF) was one of the early movers in the UK BESS industry and now has operational assets in Great Britain (GB), Ireland, Germany, Texas and California.

The UK saw a slowdown in both BESS installations and submitted applications in 2024, while applications in Ireland grew by capacity, writes PV Tech Research analyst Charlotte Gisbourne.

As the year draws to a close, we look back at some of the brilliant Guest Blog contributions published on Energy-Storage.news in the last 12 months.
