中核変電所に導入するグリーン水素生成・利用を伴うSOFCトリプルコンバインドサイクルの電力安定特性

抄録

The proposed system in this study is comprised of a single solid oxide fuel cell (SOFC) unit, Gas Steam Turbine Combined Cycle, and a proton exchange membrane electrolyzer (PEMEC) for hydrogen production equipped with a hydrogen storage system. The system is connected to renewable energy sources, and in this study, is purposed for hydrogen production in the case of extra power. The SOFC is operated in a governor-free mode to adjust output according to the load pattern. The combined cycle power plant is designed to perform combustion on hydrogen fuel and SOFC exhaust heat. The hydrogen fuel is supplied by PEMEC through a hydrogen tank. Study shows that with one unit of SOFC, the power generated is quite responsive to the load demand pattern provided thus providing a power stabilization effect to the system. For a more robust response, it is suggested to increase the amount of SOFC units in the system.
