Green Plains Achieves a Milestone as CO2 from Nebraska is Sequestered in Wyoming

Key Terms

biogenic carbon dioxide technical

Biogenic carbon dioxide is carbon dioxide released when natural organic material—like plants, wood, or food waste—breaks down or is burned; it comes from the recent biological carbon cycle rather than ancient fossil fuels. For investors, this distinction matters because regulators, sustainability ratings and carbon accounting treat biogenic emissions differently from fossil emissions, affecting a company’s reported footprint, compliance obligations, eligibility for credits, and perceived progress toward climate goals (think burning firewood versus burning gasoline).

carbon capture and storage technical

Carbon capture and storage is a set of technologies that remove carbon dioxide from industrial emissions or the air and keep it isolated, usually by compressing it and injecting it deep underground for long-term storage. For investors, it matters because it can lower a company's regulatory and climate risk, create new revenue or cost opportunities, and influence future demand for energy, materials, and services—think of it as a vacuum and lockbox that helps firms meet emissions limits and avoid penalties or lost market share.

sequestered technical

Sequestered means assets, funds, documents, or other resources have been legally or operationally set aside and isolated from normal use or access, often under the control of a court, regulator, trustee, or escrow agent. For investors this matters because sequestered items are effectively unavailable for business operations or payouts until released, which can reduce liquidity, alter a company’s cash flow and valuation, and increase uncertainty about when or if those resources will be returned.

production tax credits financial

Production tax credits are financial incentives offered to support the development of certain energy projects, such as renewable power sources. They provide a dollar amount for each unit of energy produced, helping to reduce the project's overall costs. For investors, these credits can improve the project's profitability and attractiveness by making renewable energy investments more financially appealing.

carbon intensity technical

Carbon intensity measures how much greenhouse gas a company, product, or activity produces for each unit of output — for example per unit of product made, per megawatt-hour of electricity, or per dollar of revenue. Think of it like miles per gallon but for emissions: lower numbers mean less pollution for the same activity. Investors watch it because higher carbon intensity can signal increased regulatory costs, shifting customer demand, and higher risk of assets losing value as economies move toward cleaner energy.

45Z clean fuel production credit regulatory

A 45Z clean fuel production credit is a U.S. federal tax incentive that pays fuel producers a set amount for each unit of qualifying low‑carbon fuel they make, scaled by how much the fuel cuts greenhouse gas emissions over its lifecycle. Think of it like a government rebate per gallon that narrows the price gap between cleaner and conventional fuels; investors watch it because the credit can meaningfully raise producers’ revenue, justify new projects, and alter long‑term profitability and valuation.

All Three Nebraska Facilities Now Capturing CO2; First 45Z Payment Demonstrates Early Value

OMAHA, Neb.--(BUSINESS WIRE)-- Green Plains Inc. (NASDAQ: GPRE) today announced that biogenic carbon dioxide from all three of its Nebraska facilities, Central City, Wood River, and York, is now being captured, transported on the Trailblazer pipeline and permanently sequestered at Tallgrass’ southeast Wyoming sequestration hub.

“This is a significant achievement for both companies and for the Nebraskan bioeconomy,” said Alison Nelson, Tallgrass’ segment president and vice president of CO2 business development and origination. “Through collaboration with Green Plains, we are demonstrating that large-scale, commercial carbon capture and storage is now a reality.”

The company also reported receipt of its first 45Z clean fuel production credit payment of approximately $14 million, representing a portion of the 2025 production tax credits transferred under a previously announced agreement. Additional payments related to the remaining 2025 tax credits are expected in the first quarter of 2026. September year to date, Green Plains has recorded approximately $26.5 million in 45Z value generated prior to activating carbon capture systems. Under the 45Z program, eligible low-carbon fuel producers earn production tax credits based on the carbon intensity of their fuel, meaning that as the plants further reduce their carbon intensity, credit value per gallon is expected to increase.

“Our success in Nebraska shows that we’re executing on our low-carbon strategy with purpose and precision,” said Chris Osowski, President and Chief Executive Officer. “With each step forward, we’re unlocking new value and advancing our low-carbon platform that we believe will drive growth and deliver long-term value.”

With its carbon-capture initiatives firmly established in Nebraska, Green Plains continues to advance its low-carbon platform, positioning the company for stronger performance and long-term growth.
