•• Japan CCSJapan CCS started “Feasibility Study on a Total System from Electric Power Generation to CO2 Storage,” as a part of the “Innovative Zero Emission Coal Gasification Electric Power Project”funded by Japanese Government, NEDO from 2008.
•• TEPCOTEPCO has been charged to perform a study for CCS demonstration system at NakosoIGCC site.

Major activities of the FS in 2008;• Study on methods for CO2 capture and separation• Study on the amount of the CO2 captured for both 100% of syngas and 10%
of syngas treatment cases • Preliminary specification of the CCS system

• Same “MHI 2-Stage Entrained Flow Gasifier” asAir-Blown Demo. Project Applied- Important factors duly considered
(ex. increased heat flux, change in burner, change of carrier gas, impact to SGC)
• Minimized Oxygen Consumption by 2-Stage Gasification• SGC, as Monolithic Structure with Gasifier, Producing
Steam and Supplying Aux. Power Needed in Plants
