Redflow to supply transformative 20 MWh flow battery system for project in California

Redflow’s most significant storage project to date will be one of the largest flow batteries to be deployed in the U.S.

BRISBANE, Australia, June 01, 2023 (GLOBE NEWSWIRE) -- Redflow Limited (ASX: RFX), a global leader in clean energy storage, announced today that its safe, scalable, and sustainable flow batteries have been funded and approved by the California Energy Commission (CEC) for a large-scale solar and storage project, which will provide power for the Paskenta Band of Nomlaki Indians.

The 20 MWh system will be one of the largest zinc-based battery projects in the world and will represent Redflow’s largest single sale and deployment of batteries globally to date.

With this new 20 MWh project, Redflow joins a small number of commercially proven non-lithium storage providers that the CEC is funding, as it looks to compile a robust portfolio of long-duration energy storage projects. The projects represent a key step to help address an estimated 45-55 GW of long-duration energy storage required in California by 2045 to support grid reliability and the state’s clean energy transition targets.

The project will be funded by the CEC’s US$140 million long-duration energy storage grant program focused on enabling commercially proven non-lithium energy storage technologies to scale. This follows the 2 MWh system in California that Redflow installed for Anaergia in 2022 that has been successfully operating for more than a year.

“This 20 MWh project is one of several large-scale opportunities in our pipeline, and represents the next phase of our growth strategy, validating our focus on large-scale systems in the U.S. and Australia,” said Redflow Chief Executive Officer and Managing Director Tim Harris. “The market for long-duration energy storage is accelerating. CEC approval firmly establishes our presence in California, which is leading the development and support of non-lithium technologies to achieve its net-zero goals. This project is a great example of U.S.-Australian collaboration in renewable energy and supports the aims of the recent Climate, Critical Minerals and Clean Energy Transformation Compact, which cites clean energy as the third pillar of the alliance.”
