Echogen Power Systems

Echogen Power Systems, a private company based in Akron, Ohio is commercializing waste heat to power with a proprietary system. Since its founding in April, 2007, Echogen has developed a breakthrough power generation cycle called the Thermafficient® Waste Heat Recovery Engine. It uses a modified Rankine Cycle with supercritical carbon dioxide (ScCO2) as the working fluid. ScCO2 is environmentally benign, non-toxic, and has favorable heat and mass transport properties which allow for an energy dense, compact thermodynamic system.
