California to build sodium-ion battery plant for grid storage

The Sacramento facility is set to produce 4 gigawatt-hours per year and aims to start production and shipments in Q1 2027, targeting lower utility storage costs.

OilPrice reports that Peak Energy is building a 183,000-square-foot sodium-ion battery manufacturing plant in Sacramento, Northern California.

The site is expected to produce 4 gigawatt-hours of grid-scale sodium-ion energy storage systems annually, enough to power almost four million households, and it will be the first U.S. production location dedicated solely to utility-grade grid storage using sodium-ion technology.

The project is designed for peak-demand use and, according to Peak, its passively cooled battery systems manage operational heat without fans or liquid pumps, which the company says can cut long-term operating expenses.

Peak Energy also said in a press release that the technology can reduce energy storage costs by 20% and provide 99% guaranteed uptime, with production and shipments planned to begin in Q1 2027.
