Recently, CATL signed a Memorandum of Understanding with Alfen N.V., a leading new energy integrator in Europe. The two parties plan to deploy 5 GWh of Tianheng sodium-ion battery energy storage systems in Western European countries such as the Netherlands starting from 2027.

The Tianheng sodium-ion battery energy storage system boasts a 25-year ultra-long lifespan, with an overall RTE increase of nearly 2% and lower life cycle costs. At the same time, it is compatible with LFP systems, allowing Alfen to be more flexible in battery material selection and reducing the impact of lithium price fluctuations.

This signing marks the first deployments of the Tianheng sodium-ion battery energy storage system in the European market. Seizing this opportunity, CATL will accumulate localized experience in applying sodium-ion batteries on the European power grid, enhance product compatibility with European grid standards, thereby accelerating the large-scale popularization of sodium-ion battery energy storage technology in Europe and promoting Europe's zero-carbon and diversified energy transition.
