16 IGCC Commercial Plant 15 Coal Gas Turbine Gasifier Acid Gas Removal Net Output PRB or Eastern Bituminous 501G-type GT (2 on 1) Air-Blown Gasification with Dry Coal Feed MDEA or Selexol (Sulfur Recovery) 900MW Class (w/o Carbon Capture)

17 IGCC System Configuration with Carbon Capture 16 CO+H2O CO2+H2 Coal N2 O2 Air-Blown Gasifier ASU Air for Gasifier Air Steam CO Shift Air Booster SRU AGR GT Sulfur Combustor CO2 CO2 Comp Comp Air G Sequestration H2 Rich Syngas ST G HRSG

18 CO2 Removal Required from Emission Regulation 17 About 45% carbon capture to meet 1,100 lbs/mwh Mitsubishi IGCC is feasible for more carbon capture 2500 USC CO2 Emission [lb/mwh] Highly Efficient 501G IGCC for PRB Coal CO2 Emission Threshold in CA CO2 Removal [%]

19 Comparison in CAPEX w/ and w/o Carbon Capture CAPEX of Air-Blown IGCC with Carbon Capture is almost same as or a little lower than O2-Blown!! CAPEX (%) (Net Output) Net Output (%) 18 0 ($) ($/kw) ($) ($/kw) Air-Blown O2-Blown [Comparison Inside MHI] 0

20 3. Conclusion 19 Mitsubishi IGCC Offers; 1. Air-Blown/Dry-Feed Gasifier & Low Btu/High Temp. GT Higher Plant Efficiency Higher Reliability w/ Long-Term Operation Experience MW Demonstration Plant Starting Opperation Ensuring Quality/Performance of Commercial Plant 3. Various Coals Utilization Expected Plant Efficiency Is 43-46% (HHV Basis) with G Type GT w/o Carbon Capture 4. Carbon Capture Feasibility Carbon Capture Consumes Aux. Power but Advantage of Higher Efficiency by Air-Blown IGCC Is Maintained 5. After Demonstration Plant Project Ready for North American Commercial Plant Operation in 2013/2014
