Commercial Gasification Systems

Gasification of abundant U.S. coal provides an alternative to coal-fired combustion systems as it is more efficient and environmentally friendly.

Coal gasification is a well-proven technology that began with the production of coal gas for towns and progressed to the production of fuels, such as oil and synthetic natural gas (SNG), chemicals, and more recently, to large-scale integrated gasification combined cycle (IGCC) power generation. Currently, the number of operating IGCC power plants is small; however, as listed in Appendix D, several power projects are under construction or in the planning and design stages, and gasification technology is the center of future U.S. energy complexes that are under development and discussed in detail in Chapter 7 (Future Power Generation). This section briefly discusses the gasification technologies used in commercial applications. A description of an IGCC power plant and details of the IGCC power plants in operation and proposed for the future are given in Chapter 7.
