The North Dakota integrated carbon storage complex feasibility study.

• Broom Creek Formation is a promising reservoir for CO 2 storage. • North Dakota has a favorable CO 2 management regulatory framework. • Project partners are supportive of carbon capture and storage in central North Dakota. The Energy & Environmental Research Center is investigating the feasibility of safely, permanently, and economically storing 50 million tonnes of CO 2 in central North Dakota, United States, over a 25-year operational period, should a business case for CO 2 storage emerge. The study is part of the U.S. Department of Energy (DOE) National Energy Technology Laboratory CarbonSAFE initiative and addresses the technical and nontechnical challenges of commercially deploying a CO 2 storage project. Evaluation of cores from two stratigraphic test wells demonstrate that the Broom Creek Formation (sandstone) is an excellent candidate for the geologic storage of CO 2 and the overlying Opeche Formation a competent cap rock.
