Peak Energy, a startup claiming to be the ‘first American venture to advance globally proven sodium-ion battery systems,’ has raised US$55 million in a Series A funding round.

DC-coupling of combined solar and energy storage plants could be a more effective way to save energy that would otherwise be clipped and ‘lost’, benefitting the grid and helping efforts to reduce the amount of carbon pumped into the air, the COO of Fluence has said.

Vertically-integrated solar energy company First Solar will be involved in the first megawatt-scale battery system announced in Arizona since it was revealed the state could put a 3,000MW energy storage deployment target in place.
