Overview

IGCC projects are successfully operating in the United States and around the world. Most of these projects are using petroleum residuals (petcoke, etc.), but coal-based IGCC is also proven at the 250 MWe level. Two of America's largest utilities -- American Electric Power and Cinergy -- announced plans in 2004 to build large (500 to 1,000 MWe) commercial-scale IGCC power projects before the end of the decade. For an introduction to the state of development of this technology, the following documents are recommended:

Project Economics

Proponents of gasification believe that the capital costs for the next generation of coal-based IGCC projects will be competitive with (or better than) pulverized coal plants. They also believe that the overall "cost of energy" (cost of electricity produced) is competitive with PC plants and also with natural gas combined cycle projects. Recent project economics papers include:

Project Financing

Coal-based IGCC projects are under active development by regulated utilities (e.g. AEP and Cinergy) and independent power producers (e.g. Excelsior Energy). At present, various financing mechanisms and government incentives are being discussed. Here are a few useful documents:

Operation and Maintenance Issues

The two U.S. and two European coal-based IGCC project have experienced various O&M issues (as to be expected with first-of-kind facilities). For a candid discussion of some of these issues see:

Coal-Based IGCC Plants - Recent Operations and Lessons Learned, Neville Holt (EPRI), 2004 Gasification Technology Conference, October 3, 2004 (13 pages).  Summary

Availability and Reliability Data
Existing coal IGCC plants have only recently achieved levels of availability deemed necessary for baseload powerplants (i.e. ≥ 90% available). However, Eastman Chemical Co. has operated a coal-to-chemicals gasification facility for more than two decades. Using a spare gasifier, the Eastman plant has achieved annual on-stream availability of 97-98% every year since 1984. Useful documents about the reliability and availability of gasifiers and IGCC facilities include:

Update on Operations and Economic Improvement Opportunities, Nate Moock (Eastman Gasification Services), 2004 Gasification Technology Conference, October 3, 2004 (22 pages).  Summary

The Experience of Snamprogetti's Four Gasification Projects, Guido Collodi and Daslav Brkic (Snamprogetti), 2003 Gasification Technology Conference, October 12, 2003 (9 pages).  Summary

Environmental Benefits and Perspective

In addition to the favorable economics described above, IGCC plants produce substantially lower levels of criteria air pollutants, consume less water, generate fewer solid wastes, and use less coal compared to other coal-based powerplants. In addition -- as Eastman has proven at its Tennessee facility -- gasification is readily amenable to cost-effective mercury remediation. Finally, IGCC provides an economically efficient pathway for the removal and storage of carbon dioxide should such capture and sequestration be required in the United States eventually.

Repowering Existing Natural Gas Facilities
A hot gasification topic at the present time is whether it is technically and economically feasible to convert existing natural gas "peak" load powerplants to IGCC baseload facilities. Recommended reading:
