Echogen, headquartered in Akron, OH, is a pioneering developer of supercritical carbon dioxide (sCO₂) pumped thermal energy storage (PTES) technology. Our proprietary sCO₂-based PTES system provides a safe, reliable, low-cost, and scalable long-duration energy storage (LDES) solution designed to accelerate the transition to baseload renewable energy.

Echogen is also extremely proud to be the technology behind the DOE POLAR project, a groundbreaking collaboration with Westinghouse Electric Company, Golden Valley Electric Authority, and the U.S. Department of Energy. This initiative will deploy a 1,200 MWh PTES system at the Healy Power Plant in Alaska, delivering a continuous output of 50 MW for 24 hours. The POLAR project will play a crucial role in stabilizing electricity supply for the Alaska Railbelt region, reducing energy costs, and improving air quality — marking a significant step forward in sustainable and resilient energy infrastructure.

Through a strategic partnership with Westinghouse Electric Company, Echogen is expanding its global footprint, bringing cutting-edge energy storage solutions to markets worldwide. By leveraging our breakthrough technology and industry-leading expertise, Echogen is shaping the future of clean, efficient, and sustainable energy storage.
