Carbon capturing and sequestration (CCS) technology captures carbon emissions produced by agricultural processes before they reach the atmosphere. The captured greenhouse gases are then processed and compressed into a liquid form that can be safely transported to a sequestration site, where the CO2 is securely and permanently injected approximately a mile underground beneath thick layers of rock with continued monitoring. After injection, the CO2 will remain trapped beneath the caprock and begin to dissolve and mineralize.

CO2 is produced as a byproduct of the manufacturing process.

CAPTURE

Rather than being released into the atmosphere, CO2 is captured, dehydrated, and compressed into a liquid using equipment that can be added onto the facility without interrupting normal manufacturing operations.

TRANSPORTATION

Liquid CO2 is gathered from each connected facility and transported in a steel pipeline to the sequestration site.

SEQUESTRATION

CO2 is injected more than a mile below the ground, far below water resources used by communities and farms, for permanent storage.

The Sequestration Site

The Mt. Simon sandstone formation in central Illinois will be used to sequester the CO2 transported by Heartland Greenway. The area is uniquely positioned to serve as the sequestration site thanks 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 sequestration 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 CCS facilities planned for the United States and around the world.
  • CCS has the potential to remove as much as 20% of total CO2 emissions from agricultural and energy production facilities.
  • Existing and proposed CCS projects can reduce global CO2 emissions by almost one-fifth and lower the cost of addressing climate change by 70%.
