Form Energy claims its aqueous air battery provides 150-hour duration storage
Game changer if this proves out in a cost competitive manner, although 'aqueous air battery' makes me think it's pumped storage?
The holy grail of energy storage has always been low-cost and long-duration. Form Energy intends on deploying a 1 MW/150 MWh system with a Minnesota utility before 2023, an unprecedented energy storage duration if successful.
Form Energy, a secretive, long-duration energy storage startup funded by Bill Gates Breakthrough Energy Ventures and other investors is unstealthing sort of.
The company has revealed that its fundamental energy storage technology is an aqueous air battery system that leverages some of the safest, cheapest, most abundant materials on the planet in order to commercially deploy a 1 MW/150 MWh long-duration storage solution.
Typical lithium ion battery storage systems provide four hours of storage compared to Forms remarkable of 150 hours of storage. Its not exactly the seasonal storage that Mateo Jaramillo, CEO of Form Energy, had spoken of in the past but its a few orders of magnitude better than what can be done today.
(Although the term, aqueous air battery system, leaves us little more informed about the startups technology than when it was stealthed.)
The CEO, an energy storage veteran, has referred to the companys product as a bi-directional power plant and claims that this level of duration allows for a fundamentally new reliability function to be provided to the grid from storage, one historically only available from thermal generation resources.
Form Energys first commercial project is a 1 MW, grid-connected storage system capable of delivering its rated power continuously for 150 hours with Minnesota-based utility Great River Energy.
Great River Energy is a not-for-profit wholesale electric power cooperative that provides electricity to 28 member-owner distribution cooperatives, serving 700,000 families, farms and businesses. Its Minnesotas second-largest electric utility.
