Capture of Carbon Dioxide
In Illinois, western Indiana, and western Kentucky, more than 255 million metric tons of CO2 are released annually from stationary sources. These sources include electric power plants, refineries, cement plants, and other industrial facilities.
Capture of CO2 for sequestration from stationary sources is easier than CO2 capture from mobile sources, such as motor vehicles. The costs of CO2 capture remain relatively high; research is under way to isolate the CO2 with cost-effective capture technologies.

Sequestration of Carbon Dioxide
Carbon sequestration (storage) is the isolation of carbon dioxide (CO2) from the earth's atmosphere. Sequestration can play a significant role in preventing continued CO2 buildup in the atmosphere.
Geological sequestration involves storing CO2 underground in rock formations that can retain large quantities of CO2 for long periods of time. The CO2 would be held in small pore spaces inherent in rocks. These pore spaces have held oil and natural gas for millions of years. It is possible that CO2 injection into coal seams and mature oil fields could assist in the extraction of coal bed methane or oil that would otherwise be left in the ground, which could help offset the costs of sequestration.
As we continue to better understand the potential for global climate change due to the burning of fossil fuels and the resulting release of CO2, it makes sense to research the ways in which we can isolate CO2 from the atmosphere.
