Navigator CO2 Ventures has announced its decision to suspend the permit process for its proposed carbon capture pipeline project in Iowa.

The planned pipeline project would transport CO2 emissions captured from large emitters, predominantly ethanol plants, to permanent storage sites.

The carbon capture pipeline set to cross five Midwest states was already denied a permit in South Dakota last month, which poses a significant setback in the company’s plans, which it said it would be adjusting in connection with the permit denial.

Now, Navigator CO2 is reviewing the carbon pipeline’s route through Iowa and has already filed a motion with the Iowa Utilities Board (IUB) to cancel a scheduling conference for the permit bid.

“Navigator is currently reviewing its Iowa route and technical specifications in light of decisions from regulatory authorities in neighboring states and individual landowner requests, which may lead to necessary revisions in Iowa,” the pipeline operator said in an official statement.

Meanwhile, the company is waiting to receive a final decision from regulators in Illinois by the end of February 2024, after which it hopes to file an update on the pipeline project again in Iowa.
