Pumped hydro energy storage (PHES) is one of the strongest candidates for long duration energy storage. As the UK’s energy demand increases, it is becoming paramount to have sufficient levels of renewable energy storage available to cater for this.
Invinity Energy Systems and Eos Energy Enterprises are providing long duration energy storage systems to the ‘biggest renewables microgrid project in the US’, being developed for the Viejas Tribe of Kumeyaay Indians in Southern California.
Nissan, Renault and Mercedes-Benz are at the forefront of providing EV batteries for companies developing second life battery energy storage systems (BESS), but the market for such batteries is still thinly-traded.
