What Is Coal Gasification
• As an alternative to burning coal, the process of gasification coverts coal from a solid state into a gas
• The gas—mostly of hydrogen and carbon monoxide and very similar to natural gas—can be used to make
chemicals and/or electric power
What is Integrated Combined Cycle (IGCC)?
It is the combining of a gasification plant with a combined cycle of electric generating plant.
Oxygen
Analogy of FutureGen: Polk Power Plant
• IGCC complete in 1996
• Operated by Tampa Electric
• 250 Mw output
• Least-cost dispatch on Tampa system

FutureGen, Climate Change, and Illinois’ Geological Framework Fit Together
“ One of FutureGen’s fundamental goals is to overcome environmental constraints, especially potential climate change
impacts of CO2 emissions, associated with producing electricity and other forms of energy from coal.”

Sequestration at Mattoon and Tuscola
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.

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.
