In 1984, the first commercial scale IGCC demonstration plant was operated at the Cool Water thermal power station in the United States. In Japan, the 200t/d IGCC Pilot Plant Project had started in 1986 with adoption of the air blown entrained flow type gasifier by the Engineering Research Association for Integrated Coal Gasification Combined Cycle Power Systems (IGC Association). Through the trouble shooting and modification of the gasifier, the Pilot Plant achieved 789 hours of continuous operation. Due to the knowledge and experience of early IGCC pioneers, the first Japanese IGCC Demonstration Plant is now under operation successfully. The Demonstration Project is being executed by Clean Coal Power R&D Co., Ltd. A long term continuous operating has already been achieved in 2008, and it is advanced well aiming at commercial plant.
