Gevo North Dakota ethanol plant captures CO2 for permanent storage and issues Puro.earth CORCs

Gevo's Richardton, North Dakota ethanol plant is capturing fermentation CO2 and injecting it about 6,500 feet underground into the Broom Creek Formation. The project has issued more than 623,000 Puro.earth CORCs, each representing a verified metric ton of CO2 removal with a 1,000-year durability rating. That makes it the first ethanol plant to generate CORCs under Puro's Geologically Stored Carbon methodology. Most of the corn supply comes from within 75 miles, and the plant paid roughly $86 million to local farmers in 2025. The site currently makes about 65 million gallons of ethanol per year and plans to expand to 75 million gallons. Permanent CO2 storage capacity is around 180,000 metric tons annually.

623k CORCs is a real milestone for linking ethanol to durable CO2 removal. The 1,000+ year storage designation matters for buyers who want permanence. Curious how much of the injection cost is covered by credits versus ethanol revenue.

Good read on how a grain cooperative project turned into a carbon removal play. The local sourcing detail stands out, 98% of corn within 75 miles. Keeps the supply chain short. The missing piece is how CORC prices compare to 45Q tax credit value.

The interesting part is the injection well, not the ethanol. Class VI permitting and long-term liability are where projects stall. They claim 180k metric tons per year storage, which is small but real. Would like to see injection monitoring data and whether they hit that rate consistently.

Straightforward recap of the Gevo North Dakota tour. Ethanol plant captures fermentation CO2, injects it 1.3 miles down, and sells verified removal credits through Puro.earth. 623,819 CORCs issued so far. Worth reading if you follow carbon removal procurement or rural project economics.

One policy angle: Puro CORCs are voluntary market instruments, while 45Q gives a per-ton subsidy for geologic storage. A project can tap both, but the accounting and additionality rules decide whether that stacks cleanly. The article doesn't break down revenue, which is the part most people need.
