What Echogen Power Systems does
Echogen Power Systems, founded in 2007 in Akron, Ohio by Philip Brennan, develops and commercializes supercritical carbon dioxide (sCO2) power cycle technology for energy storage, waste heat recovery, and industrial decarbonization. The company's product portfolio is organized into three solution areas: Pumped Thermal Energy Storage (PTES) systems for grid-scale long-duration energy storage (50-200 MW capacity, 8-100 hour duration, >60% round-trip efficiency) that store electricity as thermal energy in abundant materials like water and concrete; the EPS family of waste heat recovery systems (EPS100 at 8 MW, EPS35, EPS30) that convert industrial waste heat into clean electricity using closed-loop sCO2 Rankine cycles; and high-temperature sCO2 industrial heat pumps (150-500°C) that deliver process heat to replace fossil-fueled boilers. The technical foundation rests on proprietary turbomachinery and precision-engineered CO2 cycle designs protected by 90 issued patents and 37 pending applications, built from licensed NASA absorption heat pump IP and refined over nearly two decades of development.
Echogen's business model combines three revenue streams: technology licensing royalties (exemplified by a 2021 licensing deal with Siemens Energy), direct hardware and project sales of PTES and WHR systems to utilities and industrial customers, and collaborative project development with strategic partners for utility-scale deployments. Go-to-market is enterprise field sales targeting utilities and grid operators (primary segment), energy-intensive industrial facilities including steel, cement, refining, and chemicals (primary segment), and secondary use cases spanning data centers, microgrids, and remote/islanded grids. Distribution is delivered through direct enterprise sales, OEM technology licensing to Siemens Energy, and a core strategic co-development partnership with Westinghouse Electric that has over 1.2 GWh of projects in FEED phase for global PTES deployment, alongside the Slovak VVB partnership in Europe.
The company is privately held and predominantly grant-funded, with over $65 million disclosed across multiple U.S. Department of Energy programs (STEP, SunShot, ARPA-E DAYS, Office of Fossil Energy, OCED, IEDO, Coal FIRST). Strategic partners include Westinghouse Electric Corporation, Siemens Energy, TC Energy, Golden Valley Electric Association, Shell, Reaction Engines, Avery Dennison, Goodyear, Mars Corporation, TotalEnergies, and Unilever, along with research collaborations with national labs (Berkeley, NREL, PNNL, University of Notre Dame) and US Navy. The company maintains a small, high-density engineering team of 11-50 employees and is led by founders Philip Brennan (CEO) and Timothy Held (CTO), with commercial leadership under Rob Bernard (CCO). Echogen has been awarded additional contracts for waste heat and waste heat-to-power facilities in Alberta (TC Energy/Siemens Energy, up to 9 MW) and is pursuing industrial decarbonization pilots globally.
