CATL Signs 5 GWh European Sodium Battery Storage Deal

CATL has signed a memorandum of understanding with Dutch energy solutions provider Alfen to supply 5 GWh of its newly launched sodium battery storage systems to Western Europe from 2027, marking the company's first planned European deployment of sodium-based energy storage. The agreement follows a separate 60 GWh contract with a Chinese power equipment manufacturer, signalling early commercial validation of CATL's sodium technology platform alongside its existing lithium battery business. CATL just proved sodium batteries work at grid scale in Europe, not just in labs or press releases. If you're building grid storage, thermal management, or integration software, you now have a proven supplier at commercial volumes—and CATL will need partners to handle European grid interconnection and local compliance.
