IGCC (Integrated Gasification Combined Cycle) Technology Overview
Conclusions
§ IGCC currently cannot compete with PC
– Cost of generation is 10-15% more
– Availability is lower (75-85% vs. 90-95%)
– PC using super-critical steam cycle catches up in efficiency
§ IGCC, however, has great commercial potential
– Ample rooms for technical advancements, performance enhancements, and cost reduction
– More cost effective to comply with stringent emission control
– More cost effective for carbon capture
– Fuel flexible - can use low cost petroleum coke
– Can co-produce transportation fuels/chemicals by polygeneration
