Peak Energy

Peak Energy is the one to know if you're tracking sodium-ion in the US specifically — it has said it operates one of the country's first large-scale sodium-ion storage systems, built on an iron-phosphate-based cathode chemistry the company says is inherently resistant to thermal runaway, a major driver of battery storage failures generally. Peak Energy's grid-scale product line targets multi-megawatt-hour storage with high round-trip efficiency across a wide operating temperature range, and the company has announced a deployment with utility partner RWE. Its roadmap calls for scaling production to multiple gigawatt-hours over the next several years as it builds out US manufacturing capacity.
