Peak Energy signed a 4.75 GWh deal with Jupiter Power for sodium-ion batteries, highlighting the technology’s potential for grid-scale energy storage. The contract spans 2027-2030, with an option for an additional 4 GWh. The deal could exceed $500 million and marks a significant step in domestic sodium-ion battery supply chain development.

The initial phase of the agreement involves delivering 720 MWh of storage in 2027, the largest single deployment of sodium-ion batteries globally. Non-lithium battery chemistries like sodium are gaining traction due to stable, cost-effective energy storage needs driven by growing grid demand from data centers and AI operations.

Peak Energy’s sodium-ion batteries boast lower O&M costs and reduced degradation over a twenty-year lifespan compared to lithium-ion. The system’s passive cooling design significantly cuts auxiliary power consumption. Peak Energy’s CEO touts sodium’s readiness for grid-scale storage, while Jupiter Power’s CTO sees the partnership as a potential game-changer for the industry.

The partnership between Peak Energy and Jupiter Power signals progress in establishing a domestic sodium-ion battery supply chain in the U.S. This follows Peak Energy’s recent launch of its grid-scale sodium-ion system, aiming to compete with China’s leadership in sodium-ion deployment. The agreement aims to scale up sodium-ion technology within the United States.
