Combined heat and power (CHP)—sometimes called cogeneration—is an integrated set of technologies for the simultaneous, on-site production of electricity and heat. R&D breakthroughs can help U.S. manufacturers introduce advanced technologies and systems to users in the United States and around the world.
CHP and distributed energy systems improve energy efficiency, reduce carbon emissions, optimize fuel flexibility, lower company operating costs, and facilitate market opportunities for the CHP share of U.S. electricity generating capacity.
The CHP R&D project portfolio tests, validates, and deploys innovative CHP and distributed energy for industry and other manufacturing applications. Our projects include advanced reciprocating engine systems (ARES), packaged CHP systems, high-value applications, fuel-flexible CHP, and demonstrations of these technologies.

Packaged CHP Systems
The development of packaged CHP systems suitable for smaller industrial facilities can enable users to avoid complicated and costly system integration and installation but still maximize performance and increase efficiency.
Developed a clean, cost-effective 370 kW microturbine with 42% net electrical efficiency and 85% total CHP efficiency. The microturbine technology maximizes usable exhaust energy and achieves ultra-low emissions levels.
Partners: Capstone Turbine Corporation, Chatsworth, CA, Oak Ridge National Laboratory, Oak Ridge, TN, and NASA Glenn Research Center, Cleveland, OH
Developed a Flexible Combined Heat and Power (FlexCHP) system that incorporates a supplemental Ultra-Low-NOx (ULN) burner into a 65 kW microturbine and a heat recovery boiler. The ULN burner helps the CHP system meet stringent emissions criteria and improves overall system efficiency in a cost-effective manner.
Partners: Gas Technology Institute, Des Plaines, IL, Cannon Boiler Works, New Kensington, PA, Integrated CHP Systems Corp, Princeton Junction, NJ, Capstone Turbine Corporation, Chatsworth, CA, Johnston Boiler Company Ferrysburg, MI, Inland Empire Foods, Riverside, CA
Developing a flexible, packaged CHP system that produces 330 kW of electrical power output and 410 kW of thermal output while increasing efficiency and reducing emissions and cost. The project resulted in one of the highest-efficiency and lowest-emissions system for a CHP project less than 1 MW in size.
Partners: Cummins Power Generation, Fridley, MN and Cummins Engine Business Unit, Columbus, IN
Developed the Boiler Burner Energy System Technology (BBEST), a CHP assembly of a gas-fired simple-cycle 100 kilowatt (kW) microturbine and a new ultra-low NOx gas-fired burner, to increase acceptance of small CHP systems.
Partners: CMCE, Inc., Santa Clara, CA, and Altex Technologies Corporation, Sunnyvale, CA
