Toward a future low-carbon society, the development of the SOFC-MGT hybrid system, in which a Solid Oxide Fuel cell (SOFC) that can generate power with high efficiency and a gas turbine are combined, has been promoted. In a program subsidized by the National Research and Development Agency New Energy and Industrial Technology Development Organization (NEDO) starting in fiscal 2015, 250 kW class demonstration systems were set up at four locations in Japan. The verification of durability and demonstrations of start/stop tests and load change tests under an actual load environment were conducted toward introduction to the market, and stable operation was verified. As a result, the introduction of the 250 kW class system to the market started in 2017. Furthermore, since fiscal 2016, in another NEDO commissioned project, the verification of the 1 MW class system, which features increased capacity, has been conducted, and the demonstration test is currently being conducted at the Nagasaki Works of Mitsubishi Hitachi Power Systems, Ltd. (MHPS).
