Integrated Gasification Fuel Cell (IGFC) power plants incorporating solid oxide fuel cells (SOFCs) are attractive alternatives to traditional pulverized coal-fired and Integrated Gasification Combined Cycle (IGCC) power plants. IGFC systems are projected to achieve electrical generation efficiencies greater than 50% based on high heating value of coal, while separating at least 90% of the carbon dioxide emissions for capture and environmentally secure storage. A comprehensive IGFC system design and optimization study is presented based on recent SOFC performance testing and technology advancements. Details of the system power island cost break-down are also presented, indicating the cost-competitiveness of IGFC systems relative to other coal-fueled power generation technologies. Comparisons of the projected IGFC system efficiency and water consumption are made to pulverized coal-fired and IGCC power plants.
