Integrated Gasification Combined Cycle (IGCC) An alternative to achieving efficiency improvements in conventional pulverised coalfired power stations is through the use of gasification technology. IGCC plants use a gasifier to convert coal (or other carbonbased materials) to syngas, which drives a combined cycle turbine. More information can be found on the gasification section.
