Peak Energy plans 4 GWh sodium-ion battery factory in Sacramento

Renewables Now reports that Peak Energy will build a 4 GWh sodium-ion battery manufacturing facility in Sacramento, California. The company framed the investment around grid-scale energy storage, where sodium-ion chemistry could provide an alternative to lithium-based systems for some applications. The project matters because manufacturing capacity and battery chemistry choices are increasingly tied to solar-plus-storage economics, procurement risk and domestic industrial policy.
