Summit Carbon Solutions is reassessing its long-planned Midwestern carbon capture pipeline, signaling that the project could proceed without North Dakota as a final storage destination.
The company, headquartered in Ames, Iowa, has requested an amendment to its state permits that would remove language specifying permanent carbon storage in North Dakota, suggesting a major strategic shift in its development plans. The original 2,500-mile pipeline network was designed to transport captured CO2 emissions from ethanol plants across five states to an underground sequestration site in western North Dakota.
The project promised to deliver substantial federal tax incentives and economic benefits to participating states, while supporting the ethanol industry’s push toward net-zero emissions.
However, mounting regulatory and legal obstacles have cast doubt on the project’s future configuration. Summit’s inability to secure permits in South Dakota, compounded by the state’s new law restricting the use of eminent domain for CO2 pipelines, has forced the developer to consider alternate routes.
Legal Challenges and Strategic Revisions
At an October 10 district court hearing in Iowa, Summit’s attorneys urged the court to dismiss ongoing legal challenges and send the matter back to the Iowa Utilities Board, where the company intends to revise its permit applications.
Those revisions could allow Summit to bypass South Dakota entirely, potentially cutting North Dakota out of the project’s scope as well.

If the court rejects Summit’s motion, it would mark yet another setback in a series of delays and legal confrontations that have dogged the project for over two years.
If approved, however, the company could proceed with a reconfigured plan centered on Iowa and neighboring states, abandoning earlier commitments to North Dakota storage sites.
Either way, the once-ambitious Summit Carbon Pipeline, pitched as a cornerstone of the Midwest’s emerging carbon management economy, now faces a markedly uncertain path forward.
