IL Corn Supports Marquis Carbon Injection Project to Strengthen Markets and Reduce Emissions

Last week, the U.S. Environmental Protection Agency (EPA) hosted a public hearing for Marquis Carbon Injection LLC to inject and store carbon dioxide underground at an injection well in Putnam County, Illinois.


Marquis uses, on average, over 360,000 bushels of corn every day, making a large economic impact for Illinois corn farmers. The carbon sequestration well will allow them to expand corn markets, grow ethanol production, increase on-farm conservation, and reduce carbon. In Illinois, 25% of corn is used for ethanol production, generating $4.4 billion in value of ethanol and distillers grains production.

IL Corn Growers Association (ICGA) board members attended the hearing to voice their support for the injection well. 


“As a farmer in the area, I support this carbon storage project because it will hopefully help Marquis expand and pursue low-carbon fuel markets. About a quarter of our grain here in Illinois goes into the production of ethanol, and I see this project as technology that will help the industry continue to evolve and provide a good market for our corn,” Bill Leigh, a farmer from Minonk.


New markets for ethanol, like the sustainable aviation fuel (SAF) opportunity, will not take off without ethanol plants sequestering carbon. The lower-scoring carbon intensity produced at plants like Marquis, if approved, will enable both domestic and international growth in the corn industry. This progress would boost farmer profitability and drive further investment in rural communities.

How much do you know about the farmers who came before you and the decisions that still shape Illinois agriculture today? That's what University of Illinois student Lyndon Shi set out to explore during his internship with IL Corn . What began as an archival research project became a deeper look at the history of farmer leadership, innovation and advocacy in Illinois. While digging through university archives, Lyndon uncovered an undigitized manuscript from agricultural economist Harold Guither explaining the case for checkoffs. When he mentioned the discovery to IL Corn Director Rod Weinzierl, he got an unexpected response: "Oh yeah, I know him. We worked with him." It was a reminder that agricultural history isn't as distant as it may seem. Lyndon's research connected two eras of the IL Corn Growers Association: the original organization founded in the 1890s and the modern ICGA established in the 1970s. He learned how University of Illinois agriculture dean Eugene Davenport helped organize corn growers and sent professors across the state on "Corn Gospel Trains" to share the latest farming research. One story stood out in particular: the adoption of hybrid corn. Farmers who once judged corn by the appearance of the ear had to shift their focus to yield. Lyndon sees a similar transition today, as farmers increasingly balance yield with profitability amid rising input costs. "Illinois corn farmers are very good at organizing, and they are genuinely very grassroots," Lyndon said. "They've had a much more active role in shaping policy rather than just being on the receiving end." This Summer and Fall, Lyndon will travel to Taiwan on a federal scholarship to study food security. He'll do so with a new appreciation for Illinois agriculture's global connections, including Taiwan's longstanding role as an important trading partner. Watch the full conversation on IL Corn TV to hear Lyndon's research firsthand and discover how Illinois corn's history continues to influence the future.
