大崎クールジェン酸素吹IGCC実証プロジェクトの進捗状況

抄録

Coal-fired power plants, which provide stable power at low cost, will continue to serve as base load supporting the world's increasing power demands. However, the amount of CO₂ emitted by coal utilization is larger than that of other fossil fuels. Therefore the Osaki CoolGen Project has been launched to realize innovative HELE (High Efficiency, Low Emissions) coal-fired power generation which combines an Integrated coal Gasification Combined Cycle (IGCC) / Integrated coal Gasification Fuel Cell combined cycle (IGFC) with CO₂ capture. This project is subsidized by the Ministry of Economy, Trade and Industry (until 2015 FY) and New Energy and Industrial Technology Development Organization (from 2016 FY). The oxygen-blown IGCC demonstration test, which is the base technology for IGFC, commenced in March 2017. We've achieved world-class net efficiency, environmental performance, plant reliability and flexibility. Construction of CO₂ capture unit started in April 2018 and is underway to start demonstration test.
