ALSTOM will design, construct and operate a 5 MW pilot system that will capture CO2 from a portion of boiler flue gas at the We Energies power plant in Pleasant Prairie, Wisconsin, US. The system, the first of its kind in the US, will incorporate the carbon dioxide capture processes developed by ALSTOM, a leading manufacturer of power generation systems, equipment and services.

The pilot is scheduled to be commissioned at the Pleasant Prairie Power Plant in mid-2007 and will be operated for at least one year. EPRI will conduct an engineering/environmental performance and cost analysis during the operation.

“The development of cost-effective carbon dioxide capture technology is one of the most important environmental challenges facing the utility industry in the 21st Century,” said Rick Kuester, executive vice president of We Energies. “We are pleased to partner with ALSTOM and EPRI in the development of this innovative technology.”

The ALSTOM carbon capture process uses chilled ammonia to capture CO2. This process dramatically reduces the energy required to capture carbon dioxide and isolate it in a highly concentrated, high-pressure form. In laboratory testing sponsored by ALSTOM, EPRI, Statoil and others, the process has demonstrated the potential to capture over 90% of CO2at a cost that is far less expensive than other carbon capture technologies.

The isolated CO2, once captured, can be used commercially or sequestered in suitable underground geological sites.

EPRI will conduct an extensive evaluation of the system’s performance and support the development of technological and economic analyses associated with applying the carbon-capture process on a commercial scale, primarily to larger, coal-burning power plants.

“We are very excited to reach this milestone in the development of a significant technology which has the potential to have a broad impact on the future of electricity generation,” said EPRI Vice President of Generation Chris Larsen. “Evaluating and developing technology for economical post-combustion CO2 capture is critical to ensure that we keep coal as a viable electricity generation option. Nineteen other utilities, which represent a large portion of the coal-burning utilities in the United States, have committed to support this project and we hope the results from the analysis will encourage additional participation.”

About the Electric Power Research Institute
The Electric Power Research Institute (EPRI), with major locations in Palo Alto, California, and Charlotte, North Carolina, was established in 1973 as an independent, nonprofit center for public interest energy and environmental research. EPRI brings together member organizations, the Institute's scientists and engineers, and other leading experts to work collaboratively on solutions to the challenges of electric power. These solutions span nearly every area of power generation, delivery, and use, including health, safety, and environment. EPRI's members represent over 90% of the electricity generated in the United States. International participation represents nearly 15% of EPRI's total R&D program.
