Title: Research and development efforts at the Department of Energy (DOE) supporting integrated gasification combined cycle (IGCC) demonstrations
Abstract: One of the most energy efficient systems meeting the needs of industrial and utility groups in the US in increasing numbers is the gas-turbine-based combined cycle, due large in part to the availability of relatively inexpensive natural gas. One advantage of this type of combined-cycle system is its flexibility to be readily converted into a coal-based system by converting the coal under pressure into a gaseous form that can readily be cleaned of nearly all sulfur and most nitrogen compounds originally present in the coal. Integrating and optimizing aspects of the gas-turbine and steam-turbine power generation cycle with the coal gasification process give overall efficiencies with coal that are not dramatically lower than those available with natural gas. Efforts at DOE are focused on simplifying aspects of the integration that lower the overall capital and operating costs of the IGCC without compromising environmental performance.
