4. What Is Coal Gasification As an alternative to burning coal, the process of gasification coverts coal from a solid state into a gas The gasmostly of hydrogen and carbon monoxide and very similar to natural gascan be used to make chemicals and/or electric power

5. What is Integrated Combined Cycle (IGCC)? It is the combining of a gasification plant with a combined cycle of electric generating plant.

6. Oxygen

7. Analogy of FutureGen: Polk Power Plant IGCC complete in 1996 Operated by Tampa Electric 250 Mw output Least-cost dispatch on Tampa system

10. FutureGen, Climate Change, and Illinois Geological Framework Fit Together One of FutureGens fundamental goals is to overcome environmental constraints, especially potential climate change impacts of CO 2 emissions, associated with producing electricity and other forms of energy from coal.

11. Sequestration at Mattoon and Tuscola

12. Mt. Simon Sandstone Reservoir Mt. Simon Sandstone is used for natural gas storage in Champaign County, IL at 4,000 to 4,200 ft. Mt. Simon core has been recovered from a few deep exploration wells, such as this sample from near Salem, IL at 8,467 drilled in 1966. 4,143 ft 8,467

13. CO 2 Storage in Sandstone Reservoir Pore Space Sand grain Pore space Pin head

14. Shale Caprock (Reservoir Seal) Pin head No pore space visible

15. General CO 2 Injection: Caprock/Seal Integrity Shale Seal Sandstone Reservoir

16. With FutureGen, Illinois will lead in coal gasification, carbon sequestration and hydrogen production-- all key technologies that will improve energy security for our families, provide environmental benefits and support economic growth in Illinois.
