Nebraska's 3-Plant Ethanol CCS Gamble Pays Off Big

Green Plains just proved that betting on carbon capture can deliver real money. The Omaha-based biorefining company announced in December 2025 that all three of its Nebraska ethanol plants are now actively capturing biogenic CO2 and sending it to permanent geological storage in Wyoming. The company also pocketed its first 45Z clean fuel production tax credit payment of approximately $14 million, with more expected in early 2026.

This isn't just another announcement of plans. The facilities in Central City, Wood River, and York represent among the first significant volumes of low-carbon ethanol from carbon capture and sequestration in the United States. Green Plains is proving that the economics of decarbonized ethanol can work.

How the Trailblazer Pipeline Makes It Happen

The captured CO2 travels through the Tallgrass Trailblazer pipeline, a repurposed natural gas line that runs approximately 400 miles across Nebraska, Colorado, and Wyoming. The pipeline connects to Tallgrass' Eastern Wyoming Sequestration Hub, where the carbon is injected deep underground for permanent storage.

This approach of converting existing infrastructure rather than building new pipelines minimizes environmental impact and community disruption. Tallgrass has also partnered with ADM on a similar project at its Columbus, Nebraska facility, creating a regional network for ethanol decarbonization.

The Numbers Behind the Milestone

The 45Z Clean Fuel Production Credit rewards producers based on the carbon intensity of their fuel. As Green Plains continues reducing emissions, the credit value per gallon is expected to increase, creating a financial incentive that compounds over time.

Why Nebraska Became the CCS Leader

While other states have struggled with carbon capture pipeline challenges, Nebraska moved forward with a collaborative approach. The state's regulatory environment and landowner cooperation helped Green Plains and Tallgrass execute their "Advantage Nebraska" strategy on schedule.

Nebraska Governor Jim Pillen attended the Wood River plant celebration and noted the project's economic potential. The initiative positions Nebraska ethanol producers favorably in low-carbon fuel markets, including California's Low Carbon Fuel Standard and sustainable aviation fuel opportunities.

The SAF Connection: Blue Blade Energy

Green Plains isn't stopping at carbon capture. The company is also a partner in Blue Blade Energy, a joint venture with United Airlines and Tallgrass to develop alcohol-to-jet sustainable aviation fuel technology.

The three companies invested up to $50 million in the venture, using technology from the U.S. Department of Energy's Pacific Northwest National Laboratory. If commercialized, Blue Blade could provide United with up to 135 million gallons of SAF annually. This positions Green Plains' low-carbon ethanol as a feedstock for the growing sustainable aviation fuel market.

What This Means for the Industry

Green Plains' achievement validates ethanol carbon capture at a time when the global CCUS industry is gaining serious momentum. The combination of proven technology, favorable tax credits, and existing infrastructure creates a template other producers can follow.

A Blueprint for Low-Carbon Biofuels

Green Plains' Nebraska success demonstrates that decarbonizing ethanol production is no longer theoretical. The company is capturing CO2, storing it permanently, collecting tax credits, and building partnerships that extend into aviation fuel markets.

With 11 ethanol plants now connected to the Trailblazer pipeline and infrastructure designed for expansion, Nebraska has positioned itself as a hub for low-carbon fuel production. The federal tax incentives that made this possible continue to attract investment, and real carbon is being captured while real money is being earned.
