Summit Carbon Solutions is set to face trial in a $15 million lawsuit brought by pipe manufacturer Welspun Tubular, adding further pressure to the company’s carbon capture and storage (CCS) pipeline project as it continues to navigate regulatory hurdles and route revisions across the Midwest.
The dispute stems from a contract under which Welspun was commissioned to manufacture approximately 785 miles of pipeline for Summit’s proposed multibillion-dollar CO2 transportation network.
According to court filings, the agreement, valued at roughly $183 million, was signed in 2023 to support construction of the pipeline system designed to transport captured carbon dioxide from ethanol plants across several Midwestern states for permanent geological storage.
Welspun alleges that as Summit’s project encountered regulatory delays and growing opposition, the company repeatedly sought to postpone pipeline production beyond the terms allowed under the contract.
The manufacturer claims Summit ultimately attempted to cancel the agreement, triggering a contractual cancellation fee of $15 million, in addition to reimbursement for materials already procured. Summit has denied wrongdoing, but settlement discussions have failed, and a three-day bench trial is scheduled to begin on June 15 in Delaware.
Regulatory Challenges Drive Project Changes
The legal dispute comes at a pivotal time for Summit as the company works to revise and advance its CCS infrastructure plans.
Originally, the project envisioned transporting CO2 for storage in North Dakota, but permitting challenges, including South Dakota’s rejection of a key permit application and legislation restricting the use of eminent domain for carbon pipeline projects, forced the company to reassess its strategy.
In May 2026, Summit announced a revised route that would reduce pipeline mileage in several Iowa counties and eliminate the need to cross properties in others.

Under the updated plan, captured emissions would be transported through parts of Iowa and Nebraska before being permanently stored in Wyoming, bypassing South Dakota entirely.
The proposed changes are currently under review by the Iowa Utilities Commission, which has yet to determine whether it will approve the revised route. Landowner groups and project opponents have urged regulators to reject the modifications, arguing that the new proposal raises additional concerns regarding property rights and eminent domain.
Despite the ongoing legal and regulatory challenges, Summit continues to pursue development of what remains one of the largest proposed carbon capture and storage infrastructure projects in North America. The outcome of both the Delaware lawsuit and pending regulatory decisions could play an important role in determining the project’s future trajectory.
