ADM bets the audit trail, not the tonnage

ADM is preparing to generate carbon removal credits from its carbon capture operation in Columbus, Nebraska, a facility with capacity to remove more than 800,000 tons of biogenic CO2 a year. Puro.earth is overseeing certification and issuance under its Geologically Stored Carbon methodology, Edition 2024, with initial credits expected by the end of 2026 subject to completion of the audit and verification process. If certification clears, ADM begins a 15-year crediting period.

The chain behind those credits runs through three parties: ADM captures the CO2 produced during ethanol fermentation at its Columbus corn processing complex, purifies and compresses it, then passes it to Tallgrass' transportation network, which carries it to the Eastern Wyoming Sequestration Hub for injection underground through carbon capture and storage wells. The project operates under a Wyoming Department of Environmental Quality Class VI permit, and the two companies inaugurated capture and storage operations at Columbus in 2025.

Scale is the headline at Columbus, which ADM describes as the world's largest bioethanol carbon capture facility, but what buyers of durable removals are short of is something narrower: the market is still working to expand supply, and purchasers increasingly demand robust measurement, verification and evidence of long-term storage. As this publication argued on September 22, ADM is selling an audited, permitted storage record, and the Nebraska programme rests on a Class VI permit history that predates the market it is now entering.

Kris Lutt, ADM's vice president of Innovation & Growth, points to more than a decade of experience supporting carbon capture and geologic storage, including operating Class VI wells at the company's Decatur, Illinois, facility, as the basis for connecting agricultural production to carbon removal markets at scale. He says ADM is already working with customers in its own value chains and expects the offering to reach new buyers in technology, finance, aviation and pharmaceuticals, while Jan-Willem Bode, president of Puro.earth, said certifying removal at this scale demands real rigor.

The 800,000 tons is capacity, not contracted volume, and the credits do not exist until the audit closes, which makes the offering a bet that aviation and finance will underwrite a 15-year stream of credits on the strength of a permit record before the first one is issued. Transition finance now prices project-level milestones rather than labels, and here the milestone is certification itself; the economics of that 15-year window will be set less by the fermentation CO2 at Columbus than by how quickly Puro.earth's issuance paces against the queue of engineered removal projects seeking the same verification capacity.

End of 2026 is the first test: a decade and a half of credits is a long commitment to write against an unissued instrument, and the first corporate buyers to sign will show whether durable removal clears on provenance or on tonnage.
