Peak Energy Of The United States Has Signed The World's Largest Sodium Battery Energy Storage Order

 

Peak Energy of the United States has signed the world's largest sodium battery energy storage order, with a total capacity of 4.75 GWh and a fully passive cooling design.

 

Peak Energy, a US-based grid-scale energy storage technology company, has entered into a multi-year, phased agreement with major independent power generator Jupiter Power to supply a total of 4.75 gigawatt-hours (GWh) of sodium-ion battery energy storage systems between 2027 and 2030.

 

The partnership includes defined deployment phases: the first delivery of a 720 megawatt-hour system in 2027 will set a record for the world's largest single sodium-ion battery deployment, with Jupiter Power having the option to purchase an additional 4 GWh of capacity between 2028 and 2030. The system features a fully passive cooling design, reducing auxiliary power consumption by 97% compared to lithium-ion batteries, and boasts nearly 30% improved cycle performance over 20 years, requiring no additional battery replacements throughout its lifecycle.

 

Peak Energy CEO Landon Mossburg stated that partnering with an industry leader to deploy the world's largest sodium-ion energy storage system signifies the technology's full maturity and its ability to meet the surging power demands of artificial intelligence and data centers. Jupiter Power CTO Mike Geier emphasized the company's commitment to enhancing grid stability by supporting domestic manufacturing. This over $500 million deal marks a key milestone in accelerating the adoption of sodium-ion batteries as mainstream grid energy storage.
