Large reserves of low cost coal driving technology to solve coal’s carbon management penalty- Power emissions cannot be stabilized without CCS

- Retrofitable CCS technologies are a must

Driving technologies to higher efficiency, particularly ultra-supercritical PC, is a solid strategy for lower CO2 in the near and longer term

Carbon Management solutions are promising for both the Existing Fleet and the New Fleet through:

- Efficiency improvements- Carbon neutral fuel- Post combustion capture- Alternate combustion techniques.

Carbon Capture and Storage (CCS) Getting to the future of de-carbonized power

We are moving beyond paper…..only demonstration will determine the “real” lowest cost solution

Chilled Ammonia field pilot at We Energies

• More than 30 national and international utilities funding this project through EPRI

• Designed to capture up to 15,000 tons/year of CO2

• Testing to continue through 2008

• Key Objectives:− Proof of Concept− Conduct long-term tests to

establish process integrity− Measure energy consumption− Develop techno-economic

analysis to scale the system for commercial applications
