ABSTRACT
High natural gas fuel gas prices combined with new technology developments have made IGCC a competitive option when compared to conventional combined cycle or coal steam turbine cycles. Although the initial investment costs for an IGCC plant are still comparatively high, the low level and stability of petroleum coke, coal, and oil/tar residue feedstock prices can be shown to easily overcome this disadvantage when a plant’s life cycle costs are compared over an extended time period. The ability of new IGCC technology to use a mix of low or negative value opportunity fuels has played a significant role in the commercial introduction of these systems. Co-production of Hydrogen, sulfur, Ammonia, Methanol, etc. and/or using IGCC to upgrade existing refinery products can furthermore enhance the economic viability of IGCC. Finally, a dual- or co-fired IGCC plant with natural gas and Syngas (derived from petroleum coke, coal, or residues) as the fuels can be effectively employed by power producers as a financial hedge against exaggerated fuel market price fluctuations. General Electric has developed the technology to provide power producers with a range of gas turbines that can be efficiently integrated with IGCC to generate least cost electricity while meeting environmental regulatory requirements. Today there are over five (5) GW of IGCC plants in operation or under design. IGCC gas turbines are a mature product line with a total of 34 General Electric units sold of which 19 have accumulated over 340,000 hours of operation on Syngas. The IGCC technology has reached the point where systems are commercially competitive, technologically low risk, and offer exceptional environmental performance. The introduction of the next generation of advanced gas turbines will propel IGCC systems to a previously unobtainable level of performance while simultaneously realizing a step change improvement in capital cost.
