This paper describes the advanced cooling technology and materials (directionally solidified and single-crystal superalloys) which are considered key technological factors when developing the 1500°C class high temperature gas turbine.

Adopting a 1500°C class gas turbine developed on the basis of the new technology, a combined cycle plant is likely to achieve a plant thermal efficiency of more than 55% (LHV).
