Metal-hydrogen battery company EnerVenue will open a manufacturing factory with a 1GWh annual capacity in Kentucky expected to begin production by the end of the year.

A warranty covering 20,000 cycles has been launched by Enervenue, the US startup commercialising a nickel-hydrogen battery technology.

Enervenue has already got 5GWh of customer orders for its metal-hydrogen battery for stationary storage.

Nickel-hydrogen-based battery storage company EnerVenue has struck a supply MOU of up to 420MWh while liquid metal battery company Ambri is expanding its new facility in Massachusetts, US.

Pine Gate Renewables has signed a second long-term supply memorandum of understanding (MOU) targeting an alternative to lithium-ion this week, with nickel-hydrogen battery group EnerVenue.

Nickel-hydrogen batteries have been used in space for several years, but a California company adapting the technology for storing energy here on earth has raised US$100 million in a Series A funding round.
