Navigator CO2 Ventures and Summit Carbon Solutions have proposed new pipeline projects to carry captured carbon dioxide along thousands of miles of pipeline through the Midwest into permanent underground sequestration sites, according to Vice.

In recent months, the U.S. Department of Energy has greenlit millions for carbon capture and sequestration research and development and the Biden administration has proposed investing billions in it through the Infrastructure Plan and the 2022 Federal Budget.

Advocates for the projects and similar carbon capture initiatives are billing them as a solution to cut carbon emissions; however, environmentalists have concerns about the efficiency and environmental impacts of such ventures.

Navigator CO2 advertises its proposed 1,200-mile as “forward-thinking,” as it gauges commercial interest from industrial clients, from whom they’d collect emissions straight from the source to send to a permanent underground sequestration site. 

Summit Carbon Solutions has already secured partnerships to sequester carbon from 31 ethanol refineries throughout the Midwest.

Neither project has been permitted yet, but both are gaining traction and hope to be in operation by 2024.
