The development of advanced energy technologies in Japan: IGCC: A key technology for the 21st century

Abstract Integrated coal gasification combined cycle (IGCC) power plants have been looked to as a key technology for the 21st century in order to realize high efficiency and good environmental performance for electricity generation, replacing existing coal fired power plants. Following successful completion of a 200 ton/d pilot project in Nakoso, IGCC technology development in Japan is moving from the stage of a feasibility study to a detailed study to allow final decisions for demonstration plant construction. The feasibility study, jointly conducted by the domestic electric power companies, found MHIs IGCC technology to have several advantages in efficiency and reliability. In parallel with the study, a number of R&D tests have been executed as a national project to facilitate scaling up from the pilot plant to the demonstration plant. This paper introduces the current status of the MHIs IGCC technological development.
