Project Tundra

The Project Tundra carbon capture project is being developed by Minnkota Power Cooperative at the Milton R. Young lignite-fired power station (Unit 2) in North Dakota. The project is designed to install a large-scale post-combustion CO₂ capture system using Fluor’s Econamine FG Plus (EFG+) amine technology to capture approximately 12,978 short tons of CO₂ per day, equivalent to about 4.7 million tonnes per year, representing 90% removal efficiency from treated flue gas streams. The FEED study estimates a total project capital cost of approximately $1.94 billion, including capture plant, balance-of-plant infrastructure, compression systems, and owner costs. Captured CO₂ would be compressed to pipeline specifications and transported for geologic storage and potential enhanced oil recovery as part of a broader CCS network in North Dakota. TC Energy, a primary sponsor of Project Tundra alongside Minnkota Power Cooperative, withdrew from the North Dakota carbon capture project, leaving future financing and advancement uncertain. Th
