Queensland-based battery maker Redflow (ASX:RFX) has secured $6.1 million in government funding for a 6.6 megawatt-hour (MWh) zinc-bromine flow battery system in California.
The company was previously chosen to build the long-duration energy storage (LDES) system for the Barona Band of Mission Indians.
The California Energy Commission has approved funding of $13.5 million and the Barona Tribal Community will contribute $6.1 million.
The 6.6MWh system is scheduled to come online in the 2026 financial year, with a formal timetable still to be finalised with the Barona Tribal Community.

The funding clears the way for Redflow to now start project planning in partnership with the Barona Band Project Consortium and renewable energy asset developer Ameresco.
President North America Mark Higgins says the Barona battery will be Redflow’s fourth multi-megawatt hour project in California.
“Redflow has proven its technology in the California market, and our LDES technology is highly aligned with California’s decarbonisation goals,” he says.
California is aiming to achieve 60% renewables by 2030 to pave the way for carbon neutrality by 2045.
Redflow, which has a market capitalisation of $25.6 million, expects its revenue on a dollar-per-kilowatt-hour basis and payment milestones will be similar to similar projects being rolled out in the US.
The company manufactures the ZBM3 battery, which it says is the world’s smallest commercially available zinc-bromine flow battery.
Redflow also manufactures the Energy Pod200 designed to scale its battery system up for commercial applications.
