Peak Energy Deploys First US Grid-Scale Sodium-Ion Battery

New York-based Peak Energy has shipped its first sodium-ion battery energy storage system, marking a threefold achievement: the US's first grid-scale sodium-ion battery system; the world's largest sodium-ion phosphate pyrophosphate (NFPP) battery system; and the first megawatt-hour scale system using passive cooling. This innovative design eliminates fire risks associated with active cooling systems, resulting in lower operational costs and improved reliability. The company projects shipping hundreds of megawatt-hours of its system within the next two years and is building its first US cell factory, slated for 2026 production.
