Agreements to deploy 1GWh of novel aqueous zinc battery energy storage in Texas and 500MWh in California have been struck by technology provider Eos Energy Storage, marking a massive scale-up in expected installations for the systems.

Multinational utility Engie will install a 1MW / 4MWh Eos Energy Storage zinc hybrid cathode battery system in Brazil and is expected to “exercise the system to its operational boundaries”.

Former First Solar CEO Jim Hughes has joined aqueous battery storage system maker Eos Energy Storage as chairman of its board of directors.
