Grid-scale sodium-ion battery energy storage, manufactured in the US
Peak Energy builds grid-scale sodium-ion battery energy storage systems, positioning sodium-ion as a lower lifetime-cost alternative to lithium for stationary storage — no lithium, cobalt or nickel, and passive cooling rather than active thermal management. Founded in 2023 and led by co-founder and CEO Landon Mossburg, previously at Northvolt North America and Tesla Energy. Emerged from stealth in October 2023 with a $10M seed led by Eclipse, then raised a $55M Series A in July 2024 led by Xora Innovation, Temasek's deep-tech platform, with Eclipse and TDK Ventures participating. In 2026 the company announced a 183,000 sq ft, ~$71M facility in Sacramento, California capable of 4 GWh of annual output, with production and first shipments targeted for Q1 2027, and a partnership with GM Ventures pairing General Motors sodium-ion cell technology with Peak's storage platform.
