Draft PPS18: Renewable Energy
Annex 1 Energy from Waste (Biological Processes) Technology: Electricity & Heat Generation
Biogas can be used to fuel a variety of electricity generation equipment, including spark ignition engines, dual fuel diesel engines and gas turbines. Biogas can also be used to supply heating systems (including that required to maintain the required temperature of the digester), or combined heat and power (CHP) schemes. For small schemes such as farm digesters, the energy can be used to heat the domestic water supply and central heating system. For larger systems, the gas can also be used to heat buildings outside the digestion site.
