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.
