How It Works
Cogeneration, also called combined heat and power, refers to the process of fuel being burned in a steam plant, a reciprocating engine, a gas turbine, or fuel cell to produce electricity and heat. Heat can be recovered from the engine through heat exchangers and used as a source of heat for buildings or greenhouses.
Cogeneration plants can provide high-grade heat, at 100ºC or even higher (in the case of gas turbines), which is suitable for heating older buildings in cold climates. Cogeneration can also provide low-grade heat, at 70ºC to 80ºC, which can serve buildings which are designed to take advantage of lower temperature sources of heat. Heat can be provided to clients through insulated underground district heating pipes.
Cogeneration plants are the link between sources of greenhouse gas-neutral fuels such as biogas digesters and gasification plants, and the district heating networks that can distribute the heat
produced through cogeneration.
What are the Costs?
Locating cogeneration equipment in the same facility as biogas digesters or gasification plants reduces the capital and operating costs of cogeneration. Cogeneration plants using internal combustion engines can be economically viable in capacities below one megawatt, provided the heat can be sold.
