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.

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 FutureGens 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.

• 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.
