Netherlands-based iron-air long-duration energy storage (LDES) startup Ore Energy has completed a grid-connected pilot of its 100-hour iron-air LDES system at EDF Lab les Renardières in France.

Owner-operator Fidra Energy came out of virtually nowhere to be building one of Europe’s largest BESS in the UK, the 1.4GW/3.1GWh Thorpe Marsh project. We catch up with CEO Chris Elder, about its strategy and projects but also broader BESS and clean energy financing trends.

Energy infrastructure platform Revera Energy has completed an expanded US$150 million credit facility to accelerate development and construction of its battery storage, solar, and green hydrogen project pipeline across Australia and the UK.

Europe’s energy storage market has hit a turning point. What was once a scattered, early-phase market featuring pilot projects and daring developers has swiftly evolved into a dynamic, capital-intensive infrastructure sector, writes Wood Mackenzie research associate Cecilie Kristiansen.

Home battery storage and virtual power plant (VPP) specialist Lunar Energy has raised US$102 million in an oversubscribed Series D financing round led by B Capital and Prelude Ventures.

Leading BESS owner-operators across Europe discuss the key trends around the financing and deployment of grid-scale projects, with the segment now the driver of continent-wide deployments according to trade body SolarPower Europe.

Bigger, longer-duration projects and more sophisticated deal structuring are driving the energy storage industry forward, but a lack of common approaches from transmission system operators (TSOs) remains a challenge.

Lenders requirements for contracted revenues for BESS projects in the UK appears to have softened, an executive at investment firm Triple Point said.

More BESS news from across Europe, with ContourGlobal and Alpiq striking sizeable deals in Greece and France, Iberdrola putting projects into operation in Spain, and other project news in Germany, Poland, Denmark and Southeast Europe.

The UK market saw strong interest and activity in 2025 but now appears to be shifting from a development market to one focused on execution, writes Solar Media analyst Charlotte Gisbourne.
