Combined Heat and Power (CHP)

You are here

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.

CHP System Support for Grid Modernization

CHP systems can provide support services to the modern electric grid. While technologies that are specifically designed to integrate CHP systems with the grid are not readily available, this potential is being addressed by DOE.  

Advanced Reciprocating Engine Systems (ARES)

An advanced natural gas engine/generator system can increase brake thermal efficiency, reduce NOx emissions, and decrease maintenance costs, while maintaining cost competitiveness.

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.

Descriptions are provided for each CHP R&D project.

High-Value Applications

New high-value CHP technologies and applications can offer attractive end-user economics, significant energy savings, and with reproducible results.

Descriptions are provided for each CHP R&D project.

Fuel-Flexible CHP

Accelerating market adoption of emerging technology and fuel options can improve industry competitiveness through more stable energy prices, cost savings, and decreased emissions. Examples of these technology and fuel options include a biomass gasifiers, gas turbines utilizing opportunity fuels, landfill gas cleanup and removal systems, and desulfurization sorbents for fuel cell CHP.

Descriptions are provided for each CHP R&D project.


The installation of innovative technologies and applications that offer the greatest potential for replication can provide compelling data and information to foster market uptake in manufacturing and other applications.

Descriptions are provided for each CHP R&D project.
