Energy Vault has become the latest startup with a novel, non-lithium battery energy storage technology to attract significant investment, raising US$100 million through a Series C funding round. 

Two startups seeking to disrupt the energy sector with novel long-duration energy storage technologies have formed partnerships with established industry players.

Swiss-headquartered power and automation specialist ABB has been awarded a contract by Baltimore-based utility Constellation, to manufacture seven ENVILINE energy storage systems that store train braking energy using lithium-ion batteries from battery manufacturer Saft America.
