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.

‘Liquid metal’ battery technology developed as a potential low-cost competitor for lithium-ion looks set to be used at a data centre under development near Reno, Nevada.
