Projects using novel, non-lithium battery technology have been progressed by organic flow battery firm CMBlu, liquid metal battery firm Ambri, and the NAS battery division of NGK Insulators.

Liquid metal battery company Ambri is to deliver a pilot system to Indian conglomerate Reliance Industries, which invested in the company last year.

Liquid metal battery storage startup Ambri’s technology will be demonstrated by US utility company Xcel Energy in Colorado.

Ambri, the US high temperature liquid metal battery startup, has received key UL 1973 certification for safe operation of its systems.

Ambri has received an order in South Africa for a 300MW energy storage system based on its proprietary liquid metal battery technology.

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.

NEC will be using so-called ‘liquid metal’ batteries produced by Ambri in projects that could require more than four hours’ duration of energy storage, the company announced at SPI / ESI this week.

Along with TEPCO, Mercom named other major utilities and companies with a background in oil and gas as investors in the battery storage sector during the quarter.
