America's First Grid-Scale Sodium-Ion Battery Plant Gets Its First Big Test
"In a milestone for energy storage technology, Peak Energy has selected Sacramento, California, as the home of America's first manufacturing facility dedicated to grid-scale sodium-ion battery systems," according to the sustainability news site Intelligent Living. The move "represents the first large-scale test of whether sodium-ion technology can deliver on its promise of cheaper, safer, and…
America's first grid-scale sodium-ion battery plant is set to begin production in Sacramento, California, marking a significant milestone for energy storage technology. The $71 million facility, spanning 183,000 square feet, will manufacture up to 4 gigawatt-hours of storage annually, enough to power nearly four million homes. Peak Energy, founded in 2023 by former engineers from Tesla, Enovix, and Fluence, selected the site after a nationwide search.
The plant will assemble 100,000-pound containerized storage systems using sodium-ion cells supplied by Chinese manufacturers. Peak Energy has secured over 6 GWh of customer commitments, including deals with Jupiter Power, Energy Vault, and RWE Americas. China remains the global leader in sodium-ion technology, with CATL securing a 60 GWh supply agreement with HyperStrong.
Independent testing by Rochester Institute of Technology (RIT) has shown promising results for sodium-ion batteries, with exceptional durability and heat-absorbing behavior during charging. Commercial production is expected to begin in early 2027, with shipments to Jupiter Power, Energy Vault, and RWE Americas.
