Overview

• Peak Energy delivered a 3.5 MWh sodium-ion phosphate pyrophosphate battery into a shared pilot with nine utilities and IPPs, marking the first grid-scale passive-cooled sodium-ion deployment in the US.
• Its patent-pending passive-cooling architecture removes fans, pumps and vents to eliminate thermal management failures that cause 89% of US battery fires, according to the Electric Power Research Institute.
• The design reduces auxiliary power needs by as much as 90%, cuts battery degradation by around 33% over a 20-year lifespan and saves roughly $1 million in annual operating costs per gigawatt-hour.
• The system relies on sodium sourced from the US’s largest soda ash reserves and allied supply chains to bolster domestic onshoring and energy security.
• Peak Energy is negotiating nearly 1 GWh of commercial contracts and is advancing construction of its first US sodium-ion cell factory, slated to begin production in 2026.
