Redflow batteries picked for 20-MWh project in California

Redflow Ltd (ASX:RFX), an Australia-based manufacturer of redox-flow batteries, last week said it will install a 20-MWh battery system in California as part of a project financed by the US state’s California Energy Commission (CEC).

California-based Faraday Microgrids is the project developer. Funding for its plan will come from a USD-140-million (EUR 131.1m) long-duration energy storage grant programme that aims to scale up commercially proven non-lithium energy storage technologies.

Planned to be one of the largest zinc-based battery projects globally, the facility will be Redflow’s largest single-scale installation to date. The Aussie firm will supply 2,000 of its ZBM3 battery units in 200 kWh modular energy pods, which will store electricity produced by solar plants and provide it to the Paskenta Band of Nomlaki Indians.

Redlow will deliver the hardware in 2023 and 2024, with a notice to proceed expected to be issued in July. The company will also provide technical support for the project.

According to CEC's estimates, California will need to deploy between 45 GW and 55 GW of long-duration energy storage capacity by 2045 to enhance the reliability of its grid.
