Redflow zinc-bromine battery tech awarded $13.5m CEC grant

July 3, 2024

Redflow’s zinc-bromine battery technology – which was identified as the preferred energy storage technology for the Barona Band of Mission Indians’ 6.6 MWh long duration energy storage project – has formally received approval for $13.5 million in grant funding from the California Energy Commission (CEC).

The CEC funding will be matched by Barona Tribal Community funding of $6.1m for the project, resulting in a total project budget of approximately $19.6m.

The approval will now allow Redflow to work with Barona Band Project Consortium – which includes Prosper Sustainably, Microgrid Initiatives, and strategic partner Ameresco – to commence project planning. Deployment of the Redflow system is expected for the 2026 financial year with a formal timetable to be agreed.

“Redflow expects its revenue on a $/kWh basis for this project would be roughly consistent with similar projects being delivered in the US,” a statement said. “Redflow also expects payment milestones to be broadly similar to other US projects.”

Redflow CEO and managing director Tim Harris said that approval of funding from the CEC demonstrates Redflow’s technology capabilities at a commercial multi-megawatt hour scale, and provides further evidence of demand in its core markets of Australia and the United States.

Redflow’s chief commercial officer and president North America Mark Higgins added: “The Barona battery will be Redflow’s fourth multi-megawatt hour project in California involving the CEC as a funding partner and reflects the close partnership we have developed since our first CEC-sponsored project with Anergia in 2021. Redflow has proven its technology in the California market, and our LDES technology is highly aligned with California’s decarbonisation goals. We believe this is reflected in the CEC’s ongoing confidence in selecting projects that make use of Redflow’s leading LDES solution.”
