ADM and Puro.earth Partner to Sell Carbon Removal Credits from Nebraska Bioethanol CCS Facility

ADM has partnered with Puro.earth to issue carbon dioxide removal credits from its 800,000-tonne-per-year carbon capture and storage facility at its corn processing plant in Columbus, Nebraska. The facility, which launched in November 2025, captures biogenic CO2 from ethanol fermentation, then transports it via Tallgrass's Trailblazer pipeline to a sequestration hub in Wyoming. Initial credits are expected by year-end after audit, with a 15-year crediting period for buyers in tech, finance, aviation, and pharmaceuticals. ADM already operates Class VI wells in Decatur, Illinois, giving it nearly a decade of experience in geological sequestration. The Columbus facility is claimed to be the largest bioethanol carbon capture site globally. The move signals that large agricultural processors are starting to monetize carbon removal, though the market's pricing and verification standards are still evolving.

Interesting move. ADM already runs Class VI wells in Decatur for years, so they know the regulatory side. The question is whether the CDR credits from biogenic CO2 will hold up under the different standards. Puro.earth has its own methodology, so this will be a test for that.

800k tonnes a year from a single facility is real volume. The connection to Tallgrass's pipeline and sequestration hub makes it a complete chain. Still waiting to see how the audit goes and what price these credits fetch.

The article says the Trailblazer pipeline can move 10 million tonnes per year, but this facility only contributes 800k. So there's a lot of spare capacity. Are there other capture projects planned along that route? Also, the timeline for the 15-year crediting period sounds long for a market that's still forming.

Good to see a major ag company entering the CDR market. The biogenic source is key because it's not fossil CO2. The 15-year agreement with customers from tech, finance, aviation, pharma suggests they have buyers lined up already.

The devil is in the accounting. Biogenic CO2 from ethanol fermentation is generally considered net zero if the carbon is reabsorbed, but you need to ensure the sequestration is permanent and that the ethanol itself is not displacing other uses. Puro.earth's methodology will need to be rigorous.

It's not my usual area, but I wonder about the energy input for capture and compression. The article says they purify and compress, that takes power. If that power comes from fossil sources, it eats into the net removal. They should disclose the energy source.
