Integrated Gasification Combined Cycle (IGCC) is an electric power plant generating electricity from coal and other low grade hydrocarbons by gasifying technology. An IGCC uses a high pressure gasifier to turn coal and other carbon based fuels into pressurised gas then remove impurities from the syngas prior to the power generation cycle in which a gas turbine generator generates electricity and the waste heat is used to make steam to generate additional electricity via a steam turbine.
Reference Definition by Greenfacts.org: Integrated Gasification Combined Cycle (IGCC) is a power plant using gas produced from high-sulphur coal, heavy petroleum residues or biomass. IGCC is an advanced power generation technology which allows to reduce emissions of NOx, SO2, and particulate matter and improve fuel efficiency of coal. It is a combination of two technologies. Coal gasification, which uses coal to create a clean-burning gas (syngas). Combined-cycle, which is the most efficient method of producing electricity from gas commercially available today (a gas turbine generator generates electricity and the waste heat is used to make steam to generate additional electricity via a steam turbine).
