    Toward the realization of a carbon-free society by 2050, we are developing a system that uses a solid oxide fuel cell (SOFC), which can generate electricity with high efficiency. SOFC-MGT (Micro Gas Turbine) hybrid systems have been introduced to the market after the demonstration of a 250 kW class system and are scheduled to be delivered to Gas- und Wärme-Institut Essen e.V. (GWI) in Germany in fiscal 2021 for the first time for overseas installation, following deliveries to the Marunouchi building of Mitsubishi Estate Co., Ltd., the Technical Research Institute of Hazama Ando Corporation (hydrogen utilization) and the Ibaraki Plant of Asahi Breweries, LTD (biogas utilization). We are also proceeding with the development of MW class systems that apply MGT by reflecting the elemental technology in the integrated coal gasification fuel cell combined cycle (IGFC) for the Osaki CoolGen Project. We are also promoting the development of an improved system that uses a turbocharger (TC) as an air supply source instead of the MGT. The TC system uses a cascade system, which combines SOFCs in two stages and is expected to improve partial load efficiency. The demonstration tests are scheduled to be conducted in 2021.
