North Dakota CarbonSafe Phase II: Integrated Carbon Storage Complex Feasibility Study

This project undertook a comprehensive evaluation of two distinct study areas in North Dakota, each associated with a geologic storage complex situated near a coal-fired power facility. The first area is adjacent to the Basin Electric Power Cooperative (BEPC)-owned Great Plains Synfuels Plant (GPSP), which already has CO2 capture technology and an operational CO2 pipeline. The second area is near the Minnkota Power Cooperative (Minnkota)-owned Milton R. Young Station (MRYS). Both locations benefit from North Dakota's forward-thinking laws regarding pore space ownership and the management of long-term liability, which are conducive to carbon capture and storage (CCS) projects.

Key activities within the project included the drilling of two new wells for geologic characterization, the incorporation of data from an existing 3-D seismic survey, and the development of a geologic model that was used for simulating CO2 injection. A risk assessment was conducted to evaluate potential issues, and public outreach efforts were made to engage and inform the community about the project. Additionally, a site development plan was created based on the findings of these activities.

The project also involved testing the effectiveness of certain tools provided by the National Risk Assessment Partnership, aimed at evaluating the risks associated with CCS projects. These tools are essential for ensuring that CCS operations are conducted safely and effectively, minimizing any potential negative impacts on the environment and public health.
