Sustainable Aviation Fuel: Review of Technical Pathways

This U.S. Department of Energy report, prepared by researchers from Pacific Northwest National Laboratory, the National Renewable Energy Laboratory, and the University of Dayton, reviews the technical pathways for producing Sustainable Aviation Fuel (SAF) — alternative fuels designed to reduce the environmental impact of commercial aviation. The report synthesizes findings from multiple expert workshops and evaluates various methods for converting renewable resources into jet fuel. It is intended to inform policymakers, fuel producers, and aviation stakeholders about viable routes toward cleaner air travel.

Notes

U.S. Department of Energy (DOE) Office of Energy Efficiency & Renewable Energy report reviewing technical pathways for Sustainable Aviation Fuel (SAF). Prepared by Johnathan Holladay (Pacific Northwest National Laboratory), Zia Abdullah (National Renewable Energy Laboratory), and Joshua Heyne (University of Dayton). Synthesizes findings from three workshops on SAF production pathways including biofuels, alternative fuels, and aviation emissions reduction. Reviewers include LanzaTech, Commercial Aviation Alternative Fuels Initiative (CAAFI), USDA, FAA, Alaska Airlines, and Washington State University. Supported by DOE Bioenergy Technologies Office and Federal Aviation Administration.
