-
Alfen and CATL will deploy sodium-ion storage across European markets. The 5GWh agreement moves the chemistry towards commercial procurement, with grid compliance, system integration, supply resilience, and operating performance likely to determine its position alongside established lithium-ion technologies.
-
Excel Energy and Sigenergy are expanding commercial battery deployment together. Their partnership combines solar installation, storage hardware, and energy-management capability.
-
Denmark could host a major compressed-air energy-storage project beneath Mariager. Airengy and Nobian will assess an existing salt cavern for development.
-
European solar generation reached a new quarterly record this spring. Greater output is increasing negative prices, curtailment pressure, and flexibility requirements.
-
Poland has advanced plans for major pumped-storage capacity at Rożnów. The proposed plant would provide 767MW and approximately 3.1GWh of storage.
-
Belgium’s Green Turtle battery has secured financing for construction works. The four-hour system will connect directly to Elia’s 380kV transmission network.
-
Denmark’s solar parks are becoming flexible assets through battery storage. European Energy has connected 38MW and 152MWh across two co-located projects.
-
Italy is building an integrated stationary battery manufacturing value chain. FAENIX will commercialise systems produced through new LFP cell, module, assembly, and recycling capacity.
-
German battery finance is moving storage deeper into infrastructure markets. TotalEnergies has secured debt backing for eleven projects totalling 789MW and 1,628MWh.
-
Europe’s storage requirement is moving rapidly beyond incremental deployment targets. A draft action plan places storage, flexibility, and digital control at the centre of EU electrification policy.
