The program's goal is to develop a multi-megawatt (100 mW and larger) SOFC power system with at least 50% overall efficiency in converting energy contained in coal to grid electrical power. This compares to today's average U.S. coal-based power plant with an electrical efficiency of approximately 35%. Other program goals include capturing 90% or more of the system's carbon dioxide emissions and meeting a cost of $400 per kilowatt (exclusive of coal gasification unit and carbon dioxide separation subsystems).
FuelCell Energy will be responsible for the overall systems development of its coal-based multi-megawatt SOFC/turbine power plant. Other team members include Versa Power Systems, Inc., which will provide SOFC stack technology development; Gas Technology Institute, which will provide fuel cell pressurization tests; and Nexant, which will provide coal gasification expertise.
Phase I, a three-year, $10.5 million program, will focus on the design, cost analysis, fabrication and testing of large-scale SOFC stacks amenable for incorporation into 100-mW systems. Phases II and III will focus on fabricating and aggregating larger SOFC systems, as well as proof-of-concept systems to be field tested for a minimum of 25,000 hours.
