Frontier Advances CO₂-by-Rail System with Key Carbon Market Milestones
DALLAS, May 14, 2026 /PRNewswire/ — Frontier Infrastructure Holdings (Frontier), a portfolio company of Tailwater Capital and a leading developer of low-carbon infrastructure across the Mountain West and Texas, today announced several milestones that advance its CO₂-by-rail platform and strengthen market pathways for ethanol producers and other industrial emitters.
Frontier’s CO₂-by-rail system has successfully completed the preliminary assessment process with Puro.earth following a comprehensive scientific, technical, and financial review of the project’s design and methodology. As a result, the project will be listed as a Puro.earth facility, enabling inclusion in procurement materials shared with global corporate carbon removal buyers. Frontier is among a limited number of U.S.-based BECCS projects to reach this stage—and among an even smaller group to do so on its first submission—further de-risking the project’s operational and methodological framework.
“For ethanol producers and other industrial emitters, access to carbon markets depends on more than capture alone,” said Robby Rockey, President and Co-CEO of Frontier. “It requires a fully integrated chain from transportation and storage through crediting and sale. The Puro.earth milestone reflects continued progress in building a complete, bankable carbon management solution.”
“We’re excited to see Frontier reach this important milestone,” said Jan-Willem Bode, President of Puro.earth. “The team has approached this project with a strong sense of purpose, transparency, partnership and execution, and we look forward to supporting their continued progress as they help to expand the carbon removal market in the U.S.”
Wild Assets, an environmental asset management firm, has also exercised an option under its June 2025 agreement with Frontier to forward-purchase CDR credits over the next four years. This expanded commitment reflects sustained demand for Frontier’s credits and strengthens the project’s contracted revenue visibility as development progresses.
“These milestones demonstrate the coordinated execution required to advance carbon management infrastructure from concept to commercialization,” said Steven Lowenthal, Co-CEO of Frontier. “As the market continues to evolve, we believe solutions that integrate infrastructure, sequestration, and commercial access will be best positioned to deliver reliable, scalable outcomes for industrial customers.”
“Frontier continues to demonstrate the kind of execution and vision needed to help grow this market,” said Matan Rudis, Partner at Wild Assets. “We’re proud to deepen our relationship with the team and support the next phase of the project’s development.”
