Cogeneration, also known as combined heat and power, is an efficient, clean and reliable approach to the simultaneous production and utilization of electricity and thermal energy from a single fuel source. It provides benefits of higher efficiencies of fuel utilization and cost savings where there is a need for both electrical power and heat. This report is meant to provide sufficient background information on the benefits of cogeneration and to describe various cogeneration technologies that could be considered for military use when considering energy upgrades or replacement in deployment installations. The review also identifies prime mover technologies suitable for meeting the near- and long-term requirements of electric power and heat generation in the 1 kW to 500 kW range. These include reciprocating engines, Stirling engines, microturbines and fuel cell-base cogeneration systems. The report presents the principles of operation for each of these technologies, performance characteristics (efficiencies, part-load performances, fuels, emissions, and maintenance issues), as well as the strengths and weaknesses of each system.
