Frontier Infrastructure Holdings LLC has announced the launch of what it calls the first large-scale rail-based carbon management platform dedicated to North America’s ethanol producers.
Partnering with renewable fuels firm Gevo and emissions data company Verity, the initiative connects ethanol plant capture systems with permanent storage in Wyoming, using rail transport as the backbone of the model.
Pipeline development has been the traditional focus for carbon transport, but with nearly 60% of ethanol plants located more than 50 miles from current or planned CO2 pipelines, many facilities face barriers to accessing tax credits and low-carbon fuel markets.
Frontier’s solution leverages Union Pacific’s rail network, offering a modular system that could be operational in less than two years.
Anchoring at Wyoming’s Sweetwater Hub
At the center of the platform is the Sweetwater Carbon Storage Hub, which spans nearly 100,000 acres of subsurface storage capacity and hosts the country’s deepest Class VI sequestration well.
Captured CO2 will be received at the Granger Carbon Terminal (GCT), which has just secured its Notice to Proceed.
Phase I of the GCT, expected to go online in 2027, will handle 500,000 metric tons of CO2 per year, with expansion plans pushing capacity to 2 million tons as the market develops. This facility will serve as the logistics link between Midwestern ethanol plants and permanent storage in Wyoming.
The ethanol sector generates roughly 70 million tons of high-purity CO2 annually, among the most concentrated industrial streams available for capture. Frontier’s integrated “Stack to Sequestration” model packages capture, transport, storage, and digital verification.

Gevo contributes its bioenergy carbon capture and storage (BECCS) expertise, while Verity ensures transparent monitoring and reporting via blockchain-based systems.
The project’s timing is strategic. US policy currently provides generous tax credits under Section 45Q, but those incentives taper after 2032. Frontier is betting that ethanol producers will act quickly to secure access, using rail to bypass permitting hurdles that continue to slow pipeline deployment.
While designed for the US, the model could resonate globally in regions where pipeline expansion faces community or regulatory pushback.
