The Department of Energy (DOE) has been intimately involved in the development of coal combustion using pressurized fluidized beds since the 1970s. This paper presents the reasons why the DOE is pursuing the development and commercialization of Pressurized Fluidized-Bed Combustion (PFBC) systems. First generation PFBC technology is nearing commercial deployment, and the ongoing demonstrations, as part of DOE`s Clean Coal Technology (CCT) Program, will enable the technology to be a low-risk, environmentally acceptable option for utilities. Further improvements in environmental and thermal performance will be required to maintain PFBC technology as a competitive option to gasification-based power systems in the 2000s. The cost of electricity, capital costs, emissions, and thermal efficiency of PFBC systems compared to alternatives are covered. The vendors of PFBC systems seem to be responding to these market requirements. Significant progress has been made to increase the efficiency of first generation PFBCs and in reducing the capital cost of first-generation PFBC systems, which should positively influence the number of total sales of new units. The potential for first-generation PFBC systems to be used to retrofit existing utility sites and add a modest increment of power is gaining wide acceptance. Further development of PFBC systems into more efficient, environmentally benign power generation options is continuing. A snapshot of the development activities planned for Advanced PFBC systems, which the DOE considers necessary to develop utility-sized plants, are discussed. The Morgantown Energy Technology Center (METC) is Initiating an effort to investigate the technical issues associated with PFBC systems that can get to over 50 percent efficiencies and have very low emissions. The goals and development targets for this effort will be discussed.
