In an Integrated Gasification Combined Cycle (IGCC), fuel gas, which is composed of hydrogen and carbon oxides, is generated in a gasifier by coal reacting with steam and air or oxygen. The pressurized fuel gas is then cleaned and fed to a high-efficiency combustion gas turbine to generate power. The hot exhaust gas from the gas turbine produces steam to drive a steam turbine to make additional power. Integration of the inherent advantages of coal gasification and combined cycles results in an ultra high-efficiency, super-clean, low-cost power plant. IGCC plants being demonstrated can achieve efficiencies of 42% (HHV) and with continuous improvements over the next 15 to 20 years, 52% efficiency is achievable. When compared to existing coal plants with flue gas desulfurization, which have efficiencies of about 34%, IGCC reduces by 35% the CO[sub 2] emission because less coal is required to generate an equivalent power. Commercialization of IGCC will result in low-cost power from coal without environmental compromise. These features are crucial to US competitiveness in the world.marketplace. Preservation and creation of jobs will depend on a strong mining and manufacturing sector enhanced by export markets for coal and power generation equipment.
