Dakota Gasification Company's Great Plains Synfuels Plant is an international leader in technologies that capture, compress, and transport carbon dioxide (CO2) emissions from a coal gasification process. The Synfuels Plant captures more carbon dioxide (CO2) from coal conversion than any facility in the world, and is a participant in the world's largest carbon sequestration project. Dakota Gas sends carbon dioxide through a 205-mile pipeline to Saskatchewan, Canada, where oil companies use it for enhanced oil recovery operations that result in permanent CO2 geologic sequestration. The geologic sequestration of CO2 in the oil reservoir is monitored by the International Energy Agency (IEA) Weyburn CO2 Monitoring and Storage Project.
With increasing demand for the capture and storage of CO2, Dakota Gas has seen a dramatic reduction in its CO2 emissions at the Synfuels Plant. As an added environmental benefit, virtually all of the injected CO2 is expected to remain permanently sequestered in the depleted oil fields long after they have been abandoned.
Carbon sequestration is the process of removing CO2 from the atmosphere and converting it into stored compounds. There are three types of carbon sequestration: Geologic – piping CO2 from the source into extracted oil and gas fields; oceanographic – piping CO2 from the source to the bottom of the ocean; terrestrial – the long-term storage of carbon in organic matter (soil) or in trees.
The quantity of carbon offered in a trade. Carbon Sequestration Units (CSUs) equal to one metric ton of atmospheric CO2 reduced of avoided from an agreed baseline amount. To create a CSU, the amount of CO2 must be measured, verified and registered. One ton of carbon contains 3.67 tons of CO2 equivalent (atmospheric CO2).
