Power Plant Carbon Storage

Our team is supporting Rainbow Energy Center in a balance-of-plant (BOP) front-end engineering design (FEED) effort for a carbon capture facility for each of the two units at the former Coal Creek Station in Underwood, North Dakota.

The project will provide continued reliability and preserve jobs in the community, while capturing approximately 95% of the carbon dioxide (CO2) from treated flue gas. Plans to capture CO2 at Coal Creek Station would contribute to North Dakota’s goal to achieve carbon neutrality by 2030.

Our scope for this carbon capture, utilization and storage initiative includes FEED services focusing on integration of the carbon capture technology with the existing facility; locating utility interconnects; updating facility P&ID's and one-line diagrams; design of foundations, structures, ductwork, piping systems, electrical systems and substation tie-ins; model reviews; and material takeoffs. The BOP scope also includes ground-up estimates, identifying tie-in locations, and reviews of electrical, instrumentation and controls requirements.

The project will address both power generation units at the site using Mitsubishi Heavy Industries' (MHI) KM CDR™ process as the carbon capture technology provider.
