Flow battery company Redflow said it received go-ahead to start manufacturing 15MWh of long-duration energy storage at its Thailand factory for a project in California.
The order came from project developer Faraday Microgrids.
The company said it will supply its scalable Energy Pods and non-recurring engineering work. The Energy Pod200 is designed to encase 20 of its 10kWh ZBM3 zinc-bromine hybrid flow batteries. Discharge power is up to 60 kW.
The units can be grouped into banks to create microgrid or MWh-size storage. It said this phase of the work will be worth $9.23 million excluding tax.
Redflow CEO and managing director Tim Harris said the manufacturing phase with Faraday and the California Energy Commission represents “a major milestone” for Redflow’s growth in North America and is its largest project to date.
California has identified a need for 19.5GW of energy storage by 2035 and 52GW by 2045 to support the state’s energy transition, according to Redflow. The state estimates include at least 10% of those goals being met by long-duration energy storage.
The California Energy Commission (CEC) views the development of a diverse portfolio of non-lithium energy storage systems as critical to providing the state the diversification of energy storage solutions needed to meet future clean energy goals.
The state awarded the CEC $330 million in funding over the last two fiscal years to finance projects Redflow’s. The programme is expected to demonstrate how long-duration energy storage can support the state’s goal of zero-carbon electricity by 2045, as defined in the state law SB 100.
Redflow expects shipment of the batteries in late 2024. Installation and commissioning are due in early 2025.
