Sustainable aviation fuel (SAF) production in the United States is rapidly increasing as new projects come online. According to the U.S. Energy Information Administration (EIA), production of “Other Biofuels”—the category that includes SAF—nearly doubled between December 2024 and February 2025.
SAF is a renewable alternative to traditional jet fuel. It is made from agricultural waste and other biomass feedstocks and is blended with petroleum-based jet fuel for use in aircraft. Growth in SAF production is being driven by incentives from the Renewable Fuel Standard (RFS), federal tax credits, and additional support from state-level programs.
Along with SAF, the Other Biofuels category includes renewable heating oil, renewable naphtha, renewable propane, renewable gasoline, and other emerging fuels. Before 2025, renewable naphtha and propane—byproducts of renewable diesel—made up the bulk of this category. SAF contributed only a small share.
That trend is now shifting. In late 2024, U.S. SAF production capacity grew by about 25,000 barrels per day (b/d). Phillips 66 completed a 10,000 b/d SAF project in Rodeo, California, in the third quarter of 2024, though it temporarily paused production later in the year. Diamond Green Diesel launched a 15,000 b/d SAF facility in Port Arthur, Texas, during the fourth quarter of 2024.
New, smaller-scale projects are also joining the mix. In February 2025, New Rise Renewables started SAF production at its plant in Reno, Nevada, adding up to 3,000 b/d. Par Pacific is expected to begin producing SAF at its Kapolei, Hawaii, facility in the second half of 2025, with a planned capacity of 2,000 b/d.
By early 2025, total U.S. SAF production capacity had reached about 30,000 b/d. As capacity grows throughout the year, SAF is expected to become the dominant contributor to Other Biofuels output.
Production data reflect this trend. In January, U.S. production of Other Biofuels reached 33,000 b/d—a nearly 30% jump from the previous record set in September 2024. Production climbed again in February to 44,000 b/d, another 30% increase.
According to the EIA’s Short-Term Energy Outlook, U.S. Other Biofuels production is expected to more than double from 2024 to 2025 and grow by another 20% in 2026. Most of that growth will likely come from SAF.
Still, despite strong growth rates, SAF’s overall share of U.S. jet fuel consumption remains small. It is projected to make up less than 2% of the country’s 1.7 million b/d jet fuel use in 2025 and around 2% in 2026.
