    Gas turbine combined power generation can coexist with renewable energy and nuclear power generation as the cleanest and most economical form of thermal power generation facility, and therefore its long term market expansion can be expected. For further improvement in performance, the technology development of a 1700°C-class gas turbine is under way as a national project, and some of the latest developed technologies have been immediately applied to the development of the J type, which is the world's first 1600°C-class gas turbine. This paper gives a brief description about the development of the technologies that are targeted for application in next-generation gas turbines.
