Catalog of CHP Technologies
Basic Information
The Catalog of CHP Technologies (PDF) (150 pp, 2.3 MB) provides an overview of how combined heat and power (CHP) systems work and the key concepts of efficiency and power-to-heat ratios. It also provides information about the cost and performance characteristics of five commercially available CHP prime movers.

Biomass CHP Catalog of Technologies
The Biomass CHP Catalog of Technologies (PDF) (123 pp, 2.4 MB) provides resource owners, facility managers, developers, policymakers, and other interested parties with a detailed technology characterization of biomass CHP systems. The report reviews the technical and economic characterization of biomass resources, biomass preparation, energy conversion technologies, power production systems, and complete integrated systems.

Additional Information About CHP Technology
EPA's Environmental Technology Verification (ETV) Program's Greenhouse Gas (GHG) Technology Center has verified the performance of both fuel cell and microturbine systems, some of which include heat recovery systems (i.e., CHP). Both documents include the research methodology as an appendix:
- Fuel Cells (PDF) (9 pp, 398K)
- Microturbine/Combined Heat and Power (CHP) Technologies (PDF) (10 pp, 578K)
