DALLAS, Texas and FREIBURG, Germany - July 28, 2026 - Frontier Infrastructure Holdings ("Frontier"), a leading developer of low-carbon infrastructure across the Mountain West and Texas, and Carbonfuture, the leading facilitator of durable carbon removal, today announced that they have entered into a multi-year commercial agreement to bring Frontier's ethanol bioenergy carbon capture and sequestration (BECCS) carbon dioxide removal (CDR) credits to buyers across global carbon markets. The partnership represents the largest ethanol BECCS carbon removal agreement announced to date, as corporate demand for durable, high-integrity removals continues to exceed near-term supply available at scale.

Under the arrangement, 750,000 durable carbon removal credits from Project Sprint, Frontier's ethanol BECCS initiative, will be made available for purchase by corporate and institutional buyers through Carbonfuture. The agreement establishes a route to market ahead of operations, pairing Frontier's carbon capture, transport, and storage capacity with Carbonfuture's digital infrastructure and global buyer network.

"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."

Project Sprint will capture biogenic CO₂ from ethanol production and permanently sequester it in dedicated geologic storage, with sequestration expected to begin in Q4 2027. Captured CO₂ will move on Frontier's CO₂-by-rail platform, which connects ethanol producers across the Midwest to Frontier's permitted sequestration infrastructure in Wyoming, enabling producers to participate in carbon removal markets without waiting on pipeline development. The removal will be certified under Puro.earth's Geologically Stored Carbon (GSC) Methodology, with monitoring, reporting, and verification provided by Mangrove Systems.

"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."
