RWE, Peak Energy to deploy first sodium-ion battery in U.S. grid

From ESS News

The Midcontinent Independent System Operator (MISO) will receive its first sodium-ion battery thanks to a dual pilot project from battery company Peak Energy and global energy company RWE Americas. The project comes a mere eight months after Peak Energy deployed the largest grid-scale sodium-ion storage system in the United States.

Set to be deployed in Eastern Wisconsin, Peak Energy’s passively cooled, grid-scale energy storage system could be the first ripple indicating MISO’s pivot toward next-gen, non-lithium storage as the grid operator faces capacity constraints, rising costs and solar project cancellations that some industry experts suspect could slow battery deployment.
