• Frontier Infrastructure Holdings will make 750,000 durable carbon removal credits available through Carbonfuture under a multi-year agreement.
• The credits will come from Project Sprint, an ethanol BECCS project expected to begin geologic sequestration in Q4 2027.
• The project will use rail to move captured biogenic CO₂ from Midwest ethanol producers to permitted storage infrastructure in Wyoming.

Frontier Infrastructure Holdings and Carbonfuture have signed what they describe as the largest ethanol BECCS carbon removal agreement announced to date.

The multi-year deal will bring 750,000 durable carbon removal credits from Frontier’s Project Sprint to corporate and institutional buyers. Carbonfuture will provide the route to market through its carbon removal infrastructure and global buyer network.

The agreement gives Frontier commercial access to buyers before sequestration operations begin. It also provides ethanol producers with another route into carbon removal markets as demand for durable credits continues to exceed near-term supply.

Frontier builds route to market ahead of operations

Project Sprint will capture biogenic carbon dioxide generated during ethanol production. Frontier plans to transport the captured CO₂ to dedicated geologic storage sites for permanent sequestration.

Sequestration is expected to begin in the fourth quarter of 2027.

Rather than depend on new carbon pipelines, Frontier plans to move the CO₂ using its rail-based transport platform. The system is designed to connect ethanol producers across the Midwest with Frontier’s permitted sequestration infrastructure in Wyoming.

That model could broaden participation in carbon removal markets for ethanol facilities that are not located near planned CO₂ pipeline networks.

“This partnership agreement marks an important step forward for our CO₂-by-rail initiative and for the ethanol producers we serve,” said Steven Lowenthal, Co-CEO of Frontier. “Carbonfuture has built a trusted platform for durable carbon removal, and partnering with them gives our customers a practical, near-term pathway to achieving their net zero goals through a trustworthy infrastructure.”

For Frontier, the commercial agreement also helps establish demand before Project Sprint begins operations. Forward market access has become increasingly important for carbon removal developers seeking to finance projects with long construction and permitting timelines.

Certification and verification central to buyer confidence

The removals will be certified under Puro.earth’s Geologically Stored Carbon Methodology. Mangrove Systems will provide monitoring, reporting and verification.

Those controls will be central to the project’s credibility with corporate buyers. Durable carbon removal contracts increasingly depend on evidence covering carbon origin, capture, transport, storage and long-term permanence.

BECCS can generate carbon removals when biomass absorbs atmospheric CO₂ during growth and that carbon is later captured and permanently stored rather than released.

Ethanol facilities are considered particularly relevant because fermentation produces relatively concentrated streams of biogenic CO₂. That can reduce some of the technical complexity associated with capturing carbon from more diluted industrial emissions.

“Buyers are looking for durable carbon removal they can trust, at scale,” said Julie Mansfield, Head of Global Buyer Growth, Carbonfuture. “By bringing Frontier’s ethanol BECCS supply to market, this partnership expands access to verifiable, durable removals while reinforcing the rigorous standards needed to scale the sector.”

Corporate demand meets infrastructure constraints

The agreement comes as companies increasingly seek durable removals to address residual emissions within net zero strategies. Yet the market still faces limited volumes, high costs and lengthy project development cycles.

Frontier’s rail-based model addresses another constraint: transport infrastructure.

Large carbon capture projects are often built around pipelines, which can require extensive permitting, capital investment and negotiations with landowners and regulators. Rail could allow some projects to reach storage sites sooner, although operating economics and transport emissions will remain important considerations for buyers.

For executives and investors, the Frontier-Carbonfuture agreement illustrates how carbon removal markets are moving closer to infrastructure financing and long-term procurement.

The 750,000-credit commitment also offers an early test of whether ethanol BECCS can scale beyond individual facilities and connect regional industrial assets with global corporate demand.

If Project Sprint begins sequestration as scheduled in 2027, it could add a sizeable new source of durable removals while giving Midwest ethanol producers another commercial pathway for captured biogenic carbon.
