Frontier Infrastructure, in Collaboration with Gevo and Verity, Launches Complete Carbon Management Platform for Ethanol Industry

First-Of-Its-Kind Solution Combines Rail Transportation, Permanent Sequestration, And Digital Carbon Tracking To Accelerate Decarbonization

DALLAS, Sept. 22, 2025 /PRNewswire/ -- Frontier Infrastructure Holdings LLC ("Frontier"), a portfolio company of Tailwater Capital and a leading developer of low-carbon infrastructure across the Mountain West and Texas, today announced a strategic partnership with Gevo, Inc. (NASDAQ: GEVO) and its Verity platform to deliver North America's first fully integrated carbon management platform for ethanol producers. The collaboration provides end-to-end solutions from carbon capture through permanent sequestration and carbon dioxide removal and tax credit monetization.

This partnership leverages Frontier's Sweetwater Carbon Storage Hub in Wyoming—with the nation's deepest Class VI carbon storage well and nearly 100,000 acres of pore space—alongside Gevo's proven bioenergy carbon capture and storage (BECCS) expertise and its Verity digital tracking platform. Together with Union Pacific Railroad's CO₂ transportation network, the platform offers ethanol producers immediate access to carbon management infrastructure without pipeline dependencies.

"Our collaboration with Gevo and Verity eliminates the primary barriers facing ethanol producers in carbon management," said Steven Lowenthal, Co-Chief Executive Officer of Frontier Infrastructure. "By combining rail flexibility with proven sequestration and transparent tracking, we're enabling facilities to start capturing value from their CO₂ streams within 24 months rather than waiting years for alternate approaches."

Market Opportunity

The partnership targets over 200 ethanol facilities across North America producing approximately 70 million tons of high-purity CO₂ annually. The platform's rail-based approach serves a critical gap in the market, particularly benefiting the 60% of ethanol facilities located more than 50 miles from proposed pipeline routes. For these producers, the Frontier-Gevo solution represents their first commercially viable path to carbon management, enabling them to compete for premium low-carbon fuel contracts and meet evolving sustainability requirements.

Notice To Proceed: Granger Carbon Terminal (GCT)

In parallel with this announcement, Frontier has issued a formal Notice to Proceed on the Granger Carbon Terminal ("GCT")—a critical CO₂ transload facility connecting rail and truck deliveries to the Sweetwater Hub's injection infrastructure. Phase I of GCT, operational by 2027, will handle 500,000 metric tons of CO₂ annually, with expansion capability up to 2 million tons based on demand.

By leveraging Frontier's existing infrastructure and its partnership with Union Pacific Railroad, the GCT facility will serve as the hub for Frontier's "Stack to Sequestration" CO₂-by-rail solution. Initial anchor commitments have been secured from leading ethanol producers, including Midwestern Renewable Energy, an existing Verity client.

"This partnership fundamentally changes the economics and timeline for carbon management in the ethanol industry," said Jim Jandain, CEO of Midwest Renewable Energy. "Having rail transportation, permanent sequestration, and Verity's digital verification in one integrated solution means we can move from decision to implementation in under 24 months. For MRE, this is about securing our position in the low-carbon fuel market while that window is still open."
