Google Joins 5MW/50MWh Iron Flow Storage Pilot with ESS Tech
Google has partnered with ESS Tech and Salt River Project to deploy a five-megawatt, 50-megawatt-hour iron flow Energy Base storage system at SRP’s Copper Crossing Energy and Research Center in Florence, Arizona. The pilot under Project New Horizon offers commercial validation of ESS Tech’s non-lithium utility-scale storage platform while supporting Google’s carbon-free energy objectives.
1. Framework Agreement and Partners
ESS Tech signed a collaboration framework with Salt River Project and Google to advance the Project New Horizon pilot, focusing on non-lithium iron flow storage at SRP’s Copper Crossing Energy and Research Center in Florence, Arizona.
2. Pilot Specifications and Technology
The pilot will deploy ESS Tech’s five-megawatt, 50-megawatt-hour Energy Base system, showcasing iron flow battery technology designed for long-duration storage and utility-scale performance without relying on lithium-ion chemistries.
3. Commercial Validation and Strategic Implications
Completion of the pilot will serve as a commercial validation milestone for ESS Tech’s platform, while aligning with Google’s commitment to operate on carbon-free energy and supporting SRP’s evaluation of emerging long-duration energy storage solutions.
