Eslinger Biofuels and STX Group Announce Landmark Clean Fuel Partnership

Institutional Partnership Establishes Long-Term Credit Monetization Platform. $48M+ Agreement • 5-Year Term - 5MM GPY - Expansion Targeted for 2028

FRESNO, CA / ACCESS Newswire / April 7, 2026 / California has lost more than 300,000 barrels per day of refining capacity since 2020. Into that gap steps Eslinger Biofuels. The Fresno-based, CARB-certified bio-refinery today announced a landmark five-year, $48 million off-take and credit monetization agreement with STX Group, one of the world's leading environmental commodities firms, with offices across 13 markets globally. Under the agreement, STX Group assumes exclusive forward purchase rights across EBI's full compliance credit stack, comprising D4 RINs under the federal Renewable Fuel Standard, California LCFS credits, and 45Z Clean Fuel Production Credits, generating an estimated $9.3 million in annual gross credit revenue at current market rates. STX Group's commitment to a five-year exclusive with a domestic B100 biodiesel producer signals growing institutional conviction that California's compliance credit market, backed by the Federal Renewable Fuels Standard (RFS) and the 45Z Clean Fuel Production Credit, represents a durable, long-term asset class.

"This agreement gives us the institutional infrastructure to operate at the scale the market demands. California's clean fuel supply has a structural problem. Eslinger Biofuels is built to be part of the solution, and STX Group is the right partner to take us there." Jeremy Eslinger, President and CEO, Eslinger Biofuels

A Competitive Moat Few Producers Can Match

Few biodiesel producers in North America can make the claim Eslinger Biofuels has: complete, direct control over feed-stock quality and carbon intensity from collection through refining. EBI's ultra-low-carbon used cooking oil (UCO) feed-stocks are sourced through a wholly owned supply chain spanning California, Nevada, and Arizona, enabling the company to consistently generate the maximum federal and state compliance credits available per gallon. EBI's premium-grade, distilled B 100 meets CARB specifications, the most demanding diesel standards in North America, serving over-the-road transportation, commercial fleet, marine, and aviation markets. Established customers such as TA Travel Centers reflect the integrity of EBI's supply chain and the consistency of its product.

Institutional Platform, State Recognition, and 2028 Growth Roadmap

EBI's integrated model spans feed-stock sourcing, refining, and terminal distribution, capturing value at every point in the clean fuel supply chain. STX Group will lead the forward purchase and monetization of EBI's D4 RINs, LCFS credits, and 45Z credits, providing structured market access and reach into the deepest compliance credit markets available. Eco Engineers has been retained to administer EBI's D4 RIN Quality Assurance Program, ensuring full regulatory compliance as volumes scale.

California Energy Commission has affirmed EBI's strategic role in the state's clean energy infrastructure through grants totaling $7.1 million.

A $6.0 million award funded EBI's core refinery build-out. A $1.2 million grant is currently funding a 1 Megawatt solar energy and EV charging installation at the Fresno terminal, advancing the site toward its vision as a fully integrated clean energy hub for the Central Valley. This agreement is the first phase of a multi-tiered relationship. EBI has confirmed a 2028 facility expansion to be executed through technology and licensing partnerships with a leading FEED engineering firm. The expansion will add Renewable diesel and Sustainable Aviation Fuel (SAF) production while maintaining full B100 output. At scale, the Fresno terminal will serve as the leading inland clean fuel port for the Central Valley and to supply the West Coast markets.

"The 2028 expansion is the realization of a vision we have held since the beginning. A complete energy hub for Central California, delivering B100 biodiesel, renewable diesel, and sustainable aviation fuel from a single, world-class inland facility, now backed by one of the world's most respected environmental commodities firms." Jeremy Eslinger, President and CEO, Eslinger Biofuels.
