American Airlines has operated a commercial passenger flight from Corpus Christi International Airport to Dallas Fort Worth International Airport using electro-sustainable aviation fuel (eSAF). The flight demonstrated that power-to-liquid eSAF can be integrated directly into regular airport fuel supply infrastructure without requiring any special handling procedures.
The eSAF utilized on the flight was part of a batch produced and blended at Infinium’s Pathfinder facility in Corpus Christi, Texas, the world’s first commercial-scale power-to-liquids eFuels production site. Blended with conventional jet fuel and tested to meet ASTM International specifications for JetA, the flight marked the first delivery of sustainable aviation fuel from non-biobased feedstocks to a commercial airport in the United States. eSAF offers lifecycle greenhouse gas emission reductions of over 90 percent compared to standard petroleum jet fuel.
Chief Executive Officer Robert Isom stated that through the partnership with Infinium, American Airlines is demonstrating how next-generation technologies like eSAF can move from early investment to real-world application. Infinium Chief Executive Officer Robert Schuetzle noted that the company has produced drop-in eDiesel and eNaphtha at its Pathfinder facility since 2023, and adding eSAF to power a commercial passenger flight represents a meaningful step forward in low-carbon fuel solutions.
American Airlines holds an offtake agreement for commercial volumes of eSAF from Infinium’s Project Roadrunner. Project Roadrunner is currently under construction and expected to begin eSAF production and deliveries next year, with an estimated full capacity exceeding 5 million gallons annually. Figures from the International Air Transport Association (IATA) indicate that global operating and under-construction eSAF capacity totals approximately 0.02 million tonnes, with only one operational production site.
