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. 

Long duration energy storage is “essential” to help accelerate renewable deployment, according to the US Department of Energy’s Dr Imre Gyuk, who moderates this panel discussion with Matt Harper from flow battery provider Invinity Energy Systems and Russ Weed from gravity energy storage company ARES.

UK energy storage start-up Gravitricity is to build a 250kW demonstrator project in Scotland.
