Integrated Coal Gasification and Solid Oxide Fuel Cell Systems for Centralized Power Generation

摘要

FuelCell Energy is developing solid oxide fuel cell (SOFC) systems and technology for very efficient, economically viable, coal-to-electricity power plants utilizing synthesis gas (syngas) from a coal gasifier. One of the key objectives is implementation of an' innovative system concept in design of a multi-MW power plant to achieve an electrical efficiency exceeding 50% based on the higher heating value (HHV) of coal, exclusive of power requirements for CO_2 compression. The system is also designed to remove at least ninety percent of carbon in the syngas, for sequestration as CO_2. Combined with CO_2 separation technology, the Integrated Gasification Fuel Cell (IGFC) power plant is expected to achieve near-zero emissions to the environment. Development of this technology will significantly advance the nation's energy security and independence interests (through effective utilization of the nation's vast coal reserves), address pollution and greenhouse gas concerns, and help enhance the nation's economic growth.
