Research and development of hydrogen combustion turbine system in world energy network project in Japan

The power generation system employing hydrogen-combustion turbine is expected to realize a hydrogen utilization technology which will provide extremely high thermal plant efficiency(over 60% HHV Base). The hydrogen combustion turbine is the most important element in this development project. This paper describes the hydrogen-combustion turbine research and development efforts with emphasis on the hydrogen-oxygen combustor, which will be subjected to technical evaluation and model selection test in this fiscal year at the Tashiro Space Rocket Engine Test Facility Site, and the development of cooling technology for the turbine blades and vanes which will be subjected to 1700 degrees C high temperature combustion steam, both of which are the essential components in the successful development of a hydrogen-combustion turbine. This research project is part of the International Clean Energy Network Using Hydrogen Conversion Program (termed WE-NET) implemented by the New Energy and Industrial Technology Development Corporation (NEDO) under funding by the Agency of Industrial Science and Technology of the Ministry of International Trade and Industry (MITI) of Japan.
