Combined heat and power (CHP) - more efficient power generation Combined heat and power (CHP) production is the most efficient fuel-based energy production. By producing electricity and heat you maximize the use of fuels, which is energy efficient. At the same time you lower the amount of CO2 released into the atmosphere. Increased efficiency Increased efficiency Using CHP increases the efficiency of fuel use – up to 90 % of the fuels can be utilised. Low emissions Lower emissions The efficient CHP plants significantly reduce emissions, compared to separate production of electricity and heat. Fuel source flexibility Fuel source flexibility The CHP plants use various energy sources, e.g. biomass and waste. New challenges The continuous improvement of resource and energy efficiency is important in terms of the sufficiency of natural resources and climate change mitigation. CHP production addresses both of those issues because over 90% of the fuel's primary energy is used to produce district heating and electricity. Using biomass and waste Generating heat and power by adding carbon-neutral fuels to the mix dramatically reduces emissions. Unlike single source power and heat production with natural gas or coal, CHP with biomass and waste in the fuel mix reduces CO2 emissions by up to 40%. Making adjustments CHP balances the seasonality of electricity demand with intermittent production from renewables. FAQ - Combined Heat and Power What is CHP? How does CHP work? Where does Fortum use CHP? CHP and the environment CHP production is based on fuel combustion, so the main environmental impact is related to flue-gas emissions. To help mitigate this, flue gas cleaning technologies are used. Carbon-neutral fuels are added to the mix and advanced combustion techniques are used to reduce sulphur emissions and nitrogen oxides. CHP leaves behind ash, but up to 50% of the CHP ash in Europe is used by the construction materials industry for earthworks and to fill up mines.
