5 1. The development of more efficient coal-fired power plants (3) Environment-friendly coal utilization technology in Japan (power sector) Japan s coal-fired power generation has achieved the world s highest thermal efficiency (41.6%). Installed capacity (by utilities) of coal-fired power plants in Japan is 37GW, which is 1/10 of China, 1/8 of the U.S., 1/2 of India and the equivalent of Germany.

The commercialization of CCS (1) Demonstration Projects (planned) IGCC/IGFC (oxygen-blown) Capture Ready Osaki Coolgen Project IGCC (air-blown) Capture Retrofit/Pipeline/Storage Nakoso Power Plant Storage (2) Pilot Scale Projects (CCS) PCC Post-Combustion (chemical absorption) Project Nagaoka JPOWER Matsushima Coal Fired Plant PCC Oxy-fuel Callide A Coal Plant IGCC (oxygen-blown) Pre-Combustion (physical absorption) Wakamatsu Research Institute EAGLE test facilities 7

9 2. The commercialization of CCS (3) Feasibility Studies bearing in mind the total system of CCS covering injection of CO2. In regard to CCS of CO2 occurring at a coal-fired power station, developing a realistic transportation system is an important concern. During the present basic study, we will plan the realization and commercialization of the total system.

11 3. International cooperation in Clean Coal Technology (CCT) (1) Promotion of CCS projects combined with Coal-fired Power Generation Callide A (Oxy-fuel + CCS) Demonstration project by Japan and Australia (Queensland. Technical cooperation with China on CCS + EOR projects and environmental issues Japan U.S. Collaboration on CCS (July 2009) Japan Canada CCS Dialogue (Sep 2009) (2) Technical cooperation with Asian countries on CCT Japan is promoting international cooperation through multilateral frameworks such as APP and APEC, and bilateral frameworks. Major coal exporters to Japan such as Australia and Indonesia are especially important t for technical cooperation in CCT. Cooperation Program with China and India on Renovation of Existing Coal-fired Power Plants is expected to contribute to mitigating global warming.
