After legal and permitting setbacks, the Iowa-based developer said it would trim its mileage and move its planned CO2 storage site from North Dakota to Wyoming.

The developer of a long-planned carbon pipeline network in the upper Midwest unveiled major changes to the project Wednesday, saying it plans to trim its footprint by 200 miles and opting to change the storage location to Wyoming — a state previously not included.

Iowa-based Summit Carbon Solutions said it’s refining the route of its carbon dioxide pipeline project in order to “focus on the strongest and most efficient path forward,” a step that comes after legal and permitting setbacks. A North Dakota judge in March voided a storage permit for Summit, for example, and last year South Dakota Gov. Larry Rhoden (R) signed a bill into law that bans the use of eminent domain for CO2 pipelines.

The project once planned to take CO2 from ethanol plants and store the gas in an underground formation in North Dakota, but that state wasn’t mentioned in the company’s news release Wednesday.

Summit CEO Joe Griffin said refining the project is the “right step for the project and the right step for the communities counting on new opportunities,” according to the company’s release.
