Several Chinese companies active in the energy storage space have recently released their financial reports for H1 2025, with the majority posting strong growth. Their energy storage business segments have been a key driver of that growth.

Energy storage developer and system integrator Energy Vault has acquired the 125MW/1,000MWh Stoney Creek BESS in New South Wales, Australia.
