The developer of one of the world’s biggest battery energy storage systems (BESS) installed globally so far will be taking its vanadium redox flow systems into the international market, beginning with a pilot in Belgium.

Utility San Diego Gas and Electric (SDG&E) and Sumitomo Electric (SEI) have launched a 2MW/8MWh pilot vanadium redox flow battery storage project in California to study how the technology can reliably integrate renewable energy and improve flexibility in grid management.
