Peak Energy Ships America's First Grid-Scale Sodium-Ion Battery
Saturday August 2, 2025. 04:02 AM , from Slashdot
![]() According to the Electric Power Research Institute, 89% of battery fires in the US trace back to thermal management issues. Peak's design doesn't have those issues because it doesn't have those systems. Instead, the 3.5 MWh system uses a patent-pending passive cooling architecture that's simpler, more reliable, and cheaper to run and maintain. The company says its technology slashes auxiliary power needs by up to 90%, saves about $1 million annually per gigawatt hour of storage, and cuts battery degradation by 33% over a 20-year lifespan. Peak is working with nine utility and independent power producer (IPP) customers on a shared pilot this summer. That deployment unlocks nearly 1 GWh of future commercial contracts now under negotiation. The company plans to ship hundreds of megawatt hours of its new system over the next two years, and it's building its first US cell factory, which is set to start production in 2026.
