Coal still has important roles for stable and economical power generation, although CO2 emission needs to be decreased. CRIEPI has developed a high efficiency oxy-fuel IGCC system. The oxy-fuel IGCC system consists of an O2/CO2/H2O blown gasifier, dry gas clean-up process and semi closed cycle gas turbine system. The system can keep thermal efficiency more than 42%HHV even after capturing CO2. The fundamental development of each unit was successfully completed by FY 2020. On the other hand, currently, adjustment ability of supply and demand is required to respond to variable renewable energy power generations. Therefore, the authors proposed an advanced polygeneration system with CO2 capture. A main unit of the system is the O2/CO2/H2O blown gasifier developed in the above project. In addition, the gasifier is applied to use carbon-based wastes and biomass as well as coal, to decrease CO2 emission. Furthermore, the system produces both power and valuables to increase the supply and demand adjustment ability.
