More hearings begin soon for Summit's proposed CO2 pipeline. Where does the project stand?

More hearings this month and in September are set for Summit Carbon Solutions' proposed $5.5 billion, 2,000-mile pipeline network

BISMARCK, N.D. — Public utility regulators in Iowa will begin a hearing Tuesday on a proposed carbon dioxide pipeline for transporting emissions of the climate-warming greenhouse gas for storage underground that has been met by resistant landowners who fear the taking of their land and dangers of a pipeline rupture.

Summit Carbon Solutions' proposed $5.5 billion, 2,000-mile pipeline network would carry CO2 from 34 ethanol plants in five states to North Dakota for storage deep underground — a project involving carbon capture technology, which has attracted both interest and scrutiny in the U.S.

North Dakota regulators earlier this month denied a siting permit for Summit's proposed route in the state, citing myriad issues they say Summit didn't appropriately address, such as cultural resource impacts, geologic instability and landowner concerns. On Friday, Summit petitioned regulators to reconsider.

Other similar projects are proposed around the country, including ones by Navigator CO2 Ventures and Wolf Carbon Solutions, which would also have routes in Iowa.

Here is what to know about Summit's project as more proceedings begin.

WHAT IS CARBON CAPTURE?

Carbon capture entails the gathering and removal of planet-warming CO2 emissions from industrial plants to be pumped deep underground for permanent storage.

Supporters view the technology as a combatant of climate change. But opponents say carbon capture and storage isn't proven at scale and could require huge investments at the expense of cheaper alternatives such as solar and wind power, all at a time when there is an urgent need to phase out
