Osaki CoolGen ProjectOSAKI CoolGen Corporation is a joint venture with The Chugoku Electric Power Co., Inc. to commercialize IGCC, IGFC and CO2 capture and storage technologies based on the knowledge and result obtained from the EAGLE Project. As a subsidiary project funded by the Ministry of Economy, Trade and Industry, an Oxygen Blown IGCC demonstration plant (166,000 kW) is under construction in Osakikamijima-cho, Hiroshima Prefecture. It is scheduled for test runs in May 2016 and for a full-fledged demonstration in March 2017.
R&D of CCS technologyCCS※4 technology is designed to sequester CO2 emissions from power generation under the ground. Leveraging the achievements it has made in the EAGLE Project and the Callide Oxyfuel Project in Australia, J-POWER is researching and developing CCS technology.
Improving the efficiency of coal-fired power generationJ-POWER is developing next-generation technologies to reduce CO2 emissions. They are designed to further improve the efficiency of coal-fired power generation, including A-USC※1(with higher steam temperature compared to USC), IGCC※2(gas turbine power generation using gasified coal, combined with steam turbine power generation using exhaust heat) and IGFC※3(IGCC plus fuel cells). J-POWER and New Energy and Industrial Technology Development Organization (NEDO) had been working together on the EAGLE Project (Kitakyushu City) for over 10 years until 2014 to demonstrate an IGCC pilot plant and research and develop CO2 capture and storage technologies. This project laid the ground-work for the Osaki CoolGen Project, a large-scale demonstration that is underway in Hiroshima Prefecture.

Proving Trials of offshore wind power generation systemAs Japan is surrounded by sea and therefore has great poten-tial for offshore wind power generation, J-POWER and NEDO are jointly on Proving Trails of offshore wind power generation (bottom-fixed) off the coast of Kitakyushu City to develop technologies required for the introduction and commercializa-tion of offshore wind power generation.
