Dakota Gasification Company CO2 sequestration verification project—a case study of greenhouse gas reduction verification and marketing

The Dakota Gasification Company (DGC) and EnCana Corporation have jointly implemented a project to allow CO2 emissions from the Great Plains Synfuels Plant in North Dakota to be captured and used for enhanced oil recovery operations at the Weyburn Oil Field in Saskatchewan. This paper shares the experience of CH2M HILL and Natsource, LLC in quantification of primary and secondary greenhouse gas impacts of the project, registration of the project with DOE's 1605(b) program, development of a monitoring and verification plan to allow tracking of past and future emissions reductions, and analysis of strategies for monetizing the emissions reductions resulting from this cross-border project. The monetary values of the emission reductions were assessed under several different scenarios for future GHG policy.
