9 Gasification vs. Boiler

10 Efficient pollutant removal IGCC Pre-Combustion PM, Hg, Su Gasification cleans the syngas before combustion High pressure and low volume provide favorable economics for pollutant removal IGCC offers increased fuel diversity, reduced emissions, and increased siting and permitting flexibility Boiler SCR Pulverized coal Carbon Injection ESP/ FF Pollutants are removed after the coal is burned The gas volume treated is 300 times the gas volume of an IGCC plant Criteria and HAPS emissions are above an average IGCC plant Combustion produces large quantities of waste and consumes more water than IGCC FF WESP FGD CO 2 10

11 IGCC emissions approach NGCC levels Sulfur Lowest permitted sulfur emissions from a U.S. coal plant today Emits 0.01 lb/mmbtu Best PC is 0.05 lb/mmbtu Mercury Superior, cost-efficient Hg removal NOX Lowest NOX permitted plant using bituminous coals today in the US Emits 0.02 lb/mmbtu Best PC is 0.05 lb/mmbtu Lb/MMBTU IGCC benefits compared to supercritical pulverized coal in the U.S. 33% less NO x 75% less SO x Advanced PC/SCPC Average recent permit data Best individual plant IGCC capability Source: GE internal data, average of 30 permits granted 62% less CO NGCC CO 2 capture ready PM10 SO X NO x
