Evaluation of the Westinghouse solid oxide fuel cell technology for electric utility applications in Japan. Final report
For electric utility applications in Japan, conceptual designs are presented for three power plants employing the Westinghouse tubular solid oxide fuel cell (SOFC) technology. Design requirements and goals for the applications were established by the Now Energy and Industrial Technology Development Organization (NEDO), Tohoku Electric Power Company, Chubu Electric Power Company, Chugoku Electric Power Company, Kyushu Electric Power Company, the Electric Power Development Corporation, and the Electric Power Research Institute (EPRI). Two of the plants are rated at 300 MW for central station application, while the rating of the third plant, intended for dispersed siting, is 20 MW. Fuel for one 300 MW plant is coal-derived fuel gas, and the two remaining plants are fueled with liquefied natural gas (LNG). As applied in each power plant, the SOFC system is operated at near atmospheric pressure and at approximately 1000{degree}C. Heat recovered from the SOFC exhaust is used to raise steam for the generation of additional power by a steam turbine (ST) system. The project results indicate that power plant designs based upon the tubular SOFC technology can satisfy the design requirements and goals established for both central-station and dispersed-sited electric utility applications in Japan. The 300 MW LNG-fueled SOFC-ST power plant utilizes ninety-six SOFC modules, each rated at 2.5 MW. The plant achieves a full load heat rate of 6350 Btu/kWh (HHV); at 25% load, the heat rate is 5970 Btu/kWh. The-plant total capital requirement estimate ranges from $810 to $1130/kW. The 300 MW integrated coal gasification SOFC-ST power plant, also with an SOFC system consisting of ninety-six, 2.5 MW modules, is designed to produce rated power at a heat rate of 7315 Btu/kWh. The 25% load heat rate is 8620 Btu/kWh. The total capital requirement range for this plant is $1640 to $1970/kW.
