Bechtel, Cinergy/PSI, Get to Explore Building Cleaner Coal Power Plant
Integrated gasification combined cycle plants turn coal to gas, removing most of the sulfur dioxide and other emissions before the gas is used to fuel a combustion turbine generator. The hot exhaust gases are then used to heat steam, driving a steam turbine generator. The technology uses less water and has fewer emissions than a conventional coal-fired plant with currently required pollution control equipment. Another benefit is the potential to remove mercury and carbon dioxide upstream of the combustion process at a lower cost than conventional plants.
"We face the need for additional generation in Indiana," said James E. Rogers, chairman and chief executive of Cinergy Corp. "Given the high price of oil and the limited supplies of natural gas available, coal is the most practical alternative. Our challenge is to find ways to use an abundant resource in an economic and environmentally clean way. Coal gasification has proven to be efficient, and there is no cleaner coal technology."
Several months of study lie ahead before a decision will be made whether to proceed with the project and at which location. The study is expected to be completed in 90 to 120 days and will result in site-specific data for assessing the economic feasibility of the project, plant performance and output, emissions, and the plant footprint. The companies also will work together during this period to develop public and government support for the project and a preliminary project execution plan.
"We are very pleased to be participating in the beginning stages of this important project," said John Rice, president and chief executive officer for GE Energy, a division of General Electric Company. "The Cinergy proposal is clear evidence of the growing interest in this technology among utilities and power developers across the U.S. power sector today."
Scott Ogilvie, president of Bechtel Power Corporation, added: "We look forward to working with GE and Cinergy to make this IGCC project a reality for reliable, affordable, clean electricity. The current environmental benefits of this technology, coupled with the potential to meet future environmental regulations at a lower cost to the customer, can lead to the successful commercialization of an advantaged clean coal power plant for Cinergy."
