Frontier Infrastructure partners with Gevo and Verity to build North America’s first integrated ethanol-sector carbon management system.
The platform leverages rail transport to bypass pipeline limitations, linking over 200 ethanol plants to permanent sequestration.
The Sweetwater hub in Wyoming, with one of the nation’s deepest Class VI wells, anchors a system designed to capture up to 70 million tonnes of CO₂ annually.
Dallas Announcement Sets New Direction
Frontier Infrastructure Holdings LLC has launched what it calls the first full-scale carbon management platform tailored for North America’s ethanol sector. In partnership with bioenergy firm Gevo Inc. and digital emissions tracker Verity, the initiative links carbon capture at ethanol plants with permanent geological storage in Wyoming, all underpinned by a rail-based transport model.
Unlike pipeline-heavy carbon capture projects, Frontier’s system is designed to overcome geographic and permitting bottlenecks. Nearly 60% of ethanol facilities sit more than 80 kilometers from existing or planned CO₂ pipelines, limiting access to federal tax credits and low-carbon fuel markets. By securing Union Pacific’s CO₂ rail infrastructure, the partnership offers a modular alternative that could shorten project timelines to under two years.
Steven Lowenthal, Co-Chief Executive Officer at Frontier, said the model “creates a pathway for ethanol producers to monetise their CO₂ streams much faster than pipeline projects allow.”
Sweetwater Hub Anchors the Network
The platform is anchored by the Sweetwater Carbon Storage Hub in Wyoming, a site spanning almost 100,000 acres of subsurface pore space and home to the nation’s deepest Class VI sequestration well. The hub provides permanent storage capacity for captured emissions transported by rail or truck through the Granger Carbon Terminal (GCT), which has just received a Notice to Proceed.
Phase I of the GCT, scheduled to be operational in 2027, will process 500,000 tonnes of CO₂ annually, with the ability to expand to 2 million tonnes as demand grows. The terminal is designed as the logistical bridge between ethanol facilities in the Midwest and the Sweetwater sequestration site.
Targeting a 70-Million-Tonne Market
The ethanol industry produces roughly 70 million tonnes of high-purity CO₂ annually from fermentation, representing one of the most concentrated streams available for capture. Frontier’s integrated approach allows more than 200 ethanol facilities to tap into carbon capture tax credits under Section 45Q of the U.S. tax code and align with state-level low-carbon fuel standards in California and beyond.
By packaging capture, transport, storage, and digital verification, the partners aim to provide a turnkey system for producers under growing pressure to decarbonize. Gevo contributes expertise in bioenergy carbon capture and storage (BECCS), while Verity supplies blockchain-enabled tracking to verify emissions reductions and provide transparent data to regulators and buyers.

Early Commitments from Midwest Operators
Midwestern Renewable Energy, a Nebraska-based ethanol producer and longtime Verity client, is among the first to commit to the platform. Chief Executive Jim Jandain said the project gives his company a chance to access low-carbon fuel markets on a shorter timeline. “We can move from decision to execution in less than two years,” he said, noting that the firm’s ability to secure value from carbon credits depends on acting before the current policy window narrows.
The system is being framed by Frontier as its “Stack to Sequestration” strategy—an end-to-end model connecting ethanol stacks directly to permanent storage.
Policy and Market Stakes
For investors and executives, the project highlights both the promise and fragility of ethanol’s low-carbon pivot. With U.S. policymakers offering generous tax credits but permitting delays stalling pipeline infrastructure, rail-linked sequestration could reshape the economics of carbon capture for biofuels.
The integration of digital tracking also anticipates regulatory scrutiny, with emissions accounting becoming a decisive factor in accessing premium markets. By embedding monitoring and verification in the system’s design, Frontier and its partners are positioning ethanol producers to meet compliance requirements while securing commercial advantage.
Regional Play, Global Implications
While the initiative is rooted in U.S. ethanol, its design raises broader implications for global carbon management. Transporting captured CO₂ by rail or truck could become a template in regions where pipeline development faces land-use or permitting obstacles. If scaled, the model could redefine how hard-to-abate sectors participate in voluntary and compliance carbon markets.
For the ethanol industry, the platform represents both risk mitigation and opportunity capture. With federal incentives set to decline after 2032, the timeline for deployment is narrow. Frontier’s bet is that ethanol producers will move quickly to secure access, making Wyoming’s Sweetwater hub a critical node in North America’s carbon infrastructure.
