“Standalone solar is not dead, but it is challenging,” said Pierre Bartholin, head of power hedging at investor Nuveen Infrastructure, opening the debate at Solar Media’s Solar Finance Investment Europe (SFIE) conference in London on the future of co-located battery storage. 

LG Energy Solution will keep global battery cell production at around 300GWh in 2026, while increasing its proportion of supply for energy storage system (ESS) applications.

While steps are being taken, Spain still lacks the market mechanisms and regulatory framework for large-scale energy storage.

Power firm Uniper has entered into a conditional supply contract with organic solid flow battery company CMBlu Energy for the delivery of at least 5GWh of its technology.

Lithium-ion companies have come out as the top-rated suppliers on a new long-duration energy storage (LDES) leaderboard, while CO2 Battery company Energy Dome is the highest non-lithium company.

Power firm RWE is about to start building a 400MW/800MWh BESS project in Germany, among the largest in the country to reach the construction stage. In related news, Kyon Energy has connected a 282MWh project to the grid, possibly the largest in the country to reach that milestone.

PV inverter and BESS firm Sungrow has launched its PowerTitan 3.0 battery energy storage model for the European market.

European Union countries deployed record-breaking battery storage capacity for the 12th consecutive year in 2025.

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.
