Liquid metal battery firm Ambri is set to deploy its energy storage technology in a US data centre following an agreement with TerraScale.
The collaboration includes delivery of 250MWh Ambri system to TerraScale’s Energos Reno project in Nevada, which is planned to start next year.
The technology is comprised of a liquid calcium alloy anode, a molten salt electrolyte and a cathode of solid particles of antimony. The active materials in the Ambri cells reversibly alloy and de-alloy while cycling.
The storage will be used for peak shifting of renewable solar load, and grid-scale peak shaving at what Danny Hayes, chief executive officer of TerraScale, says could be “potentially the lowest levelised cost of storage in the industry”.
The Energos Reno is an industrial/commercial/residential development to be powered by thermal and solar and ‘other’ renewable energy.
Ambri batteries were born in the GroupSadoway laboratory at Massachusetts Institute of Technology. Its investors include Bill Gates, Khosla Ventures and Total SE.
Ambri’s long-duration systems can deliver daily 100% depth of discharge cycling performance for more than 20 years with negligible degradation.
