Peak and GM Partner to Scale Next-Generation Energy Storage Technology

Peak Energy, a U.S.-based company developing low-cost, giga-scale energy storage technology for the grid, today announced an agreement with RWE Americas, a leading global energy company with approximately 13 GW of operating assets in the U.S., to pilot Peak Energy's proprietary passively cooled sodium-ion grid storage battery technology.

Peak Energy, a U.S.-based company developing low-cost, giga- scale energy storage technology for the grid, today announced a multi-year phased agreement with Jupiter Power LLC (“Jupiter Power” or “Jupiter”), a leading developer and operator of utility-scale battery energy storage systems. Under the agreement, Peak Energy will supply up to 4.75GWh of its industry-leading sodium-ion battery energy storage systems (ESS) to Jupiter Power, for deployment between 2027 and 2030.

Last week in Denver, Peak hosted 47 of its customers and development partners to celebrate the power on of Peak’s product - the first passively cooled Energy Storage System in the world. With live data, a deep dive into sodium-ion chemistry, and a site visit, Peak gave guests an unfiltered look into the development of the Peak ESS, from cell to site.

Today, Peak announced the launch and shipment of its sodium-ion battery energy storage system (ESS) that delivers a patent-pending passive cooling design to dramatically reduce lifetime energy costs. Cost-competitive with state of the industry products while offering dramatically lower operating and maintenance costs, Peak Energy's product is the first ever fully passive megawatt-hour scale battery storage system, the largest sodium-ion phosphate pyrophosphate (NFPP) battery system in the world, and the first grid-scale sodium-ion storage solution ever deployed to the U.S. electric grid. Deploying the system in a shared pilot with nine leading utility and independent power producer (IPP) customers this summer, Peak Energy is fast-tracking its promise to onshore battery manufacturing.
