NEDO, along with Osaki CoolGen Corporation, a NEDO award recipient, has launched a demonstration test of an oxygen-blown integrated coal gasification combined cycle (IGCC) system as the first stage of the integrated coal gasification fuel cell combined cycle (IGFC) demonstration project called the "Osaki CoolGen Project" that aims to establish the ultimate high-efficiency coal-fired power technology.

The facility for the demonstration test has been built in Osakikamijima-cho in the prefecture of Hiroshima. It will operate a 1,300°C-class gas turbine by converting pulverized coal into gas in a gasifier and simultaneously operate a steam turbine using the heat generated from the gas turbine and the gasifier to generate electricity from the combination of both turbines. The demonstration test will work to verify the performance, reliability, and economic efficiency of the coal-fired power system, with the aim of achieving a net efficiency of approximately 46% in a commercial system using a 1,500°C-class gas turbine.
