The Japanese government has launched the "Cool Earth-Innovative Energy Technology Program[2]" in 2008 March to promote international cooperation and actively contribute to substantial global greenhouse gas emissions reductions. 21 technologies that can contribute to substantial reductions in CO_2 emissions by efficiency improvement and low carbonization were selected. The Advanced Ultra Super Critical pressure power generation (A-USC), that aims to commercialize 700 deg-C class pulverized coal (PC) power system with 46% power generation efficiency by around 2015 and 48% efficiency by around 2020, is included in the technologies. We have started a large-scale development of the A-USC technology in 2008 August. 700 deg-C class boiler, turbine and valve technologies, which include high temperature material technology, will be developed. Some candidate materials for boilers are being tested. Turbine rotor and casing materials are being developed and tested, as well.
