Italian AI infrastructure speciality Energy Dome and electric and water utility Salt River Project (SRP) have agreed to deploy a 19MW carbon dioxide (CO2) battery system in Arizona.
The project, co-located at SRP’s Coronado Generating Station (CGS), will use Energy Dome’s CO2 battery to provide 10 hours of energy storage, supporting grid reliability.
Energy Dome’s CO2 battery uses power from the grid to compress and store CO2, then, when the power is needed, expands the CO2 through a turbine to generate energy to send back to the grid.
Expected to enter service in 2029, the project will be developed under a 20-year tolling agreement.
The project is also part of Google and SRP’s collaboration to accelerate the deployment of non-lithium-ion long-duration energy storage (LDES) technologies.
Google will fund a portion of the project through a cost-sharing agreement with SRP.
Claudio Spadacini, founder and CEO of Energy Dome, noted Arizona as one of the most compelling energy markets in the US due to its sustained growth.
“At a time when AI growth and rising demand are reshaping America’s energy landscape, the CO2 battery offers [a] scalable, dispatchable capacity needed to strengthen US energy.”
