This technology fact sheet provides information on waste heat to power (WHP) systems, including data on technical potential and capital costs. By recovering thermal energy from heat that would otherwise be wasted, WHP can generate usable electrical power without the need to burn additional fuel, thereby reducing costs, improving efficiency, and reducing emissions. When waste heat is recovered from a thermal process and used to generate electricity, it is considered to be a combined heat and power (CHP) system. The U.S. Department of Energy CHP Installation Database lists 938 MW of installed WHP capacity at more than 100 U.S. sites as of 2019.
