Carbon capture projects capture carbon dioxide (CO2) emissions produced by industrial facilities that are currently being emitted into the atmosphere. During the capture process,CO2 is dehydrated and compressed into a liquid form that can be safely made available for value-added commercial industrial uses, or transported to a storage site, where the CO2 is securely and permanently injected approximately a mile underground beneath thick layers of rock. The injected CO2 is continuously monitored, and, after injection, the CO2 will remain trapped beneath the caprock and begin to dissolve and mineralize.
The Storage Site
The Mt. Simon sandstone formation in central Illinois will be used to permanently store the CO2 transported by Heartland Greenway. The area is uniquely positioned to serve as the storage site due to its proven geological properties and successful history of similar projects in the region. Tenaska and Advanced Resources International Inc., strategic members of the Navigator team, are leading development efforts for the sequestration site.
Because storage occurs deep underground, far below water resources used by communities and farms, landowners’ use of the land will remain unchanged. Landowners will be compensated for the use of their sub-surface geology, which is also called pore space.
The Heartland Greenway team will work with the U.S Environmental Protection Agency and the Illinois Environmental Protection Agency to obtain Class VI underground injection control permits. Heartland Greenway will develop a rigorous monitoring program to ensure the safety of residents and workers as well as to protect the environment.
Heartland Greenway is designed to store approximately 10 million metric tons of CO2 per year in its first year of operation and could be expanded to store up to 15 million metric tons of CO2 per year.
- There are more than 30 carbon capture facilities planned for the United States and around the world.
- Carbon capture has the potential to remove as much as 20% of total CO2 emissions from agricultural and energy production facilities.
- Existing and proposed carbon capture projects can reduce global CO2 emissions by almost one-fifth and lower the cost of addressing climate change by 70%.
