Study Finds SAF Could Fall Short Of 2030 Target

Why It Matters

The shortfall highlights a gap between policy ambitions and realistic production capacity, prompting regulators and investors to reassess timelines and support mechanisms for SAF scaling.

Key Takeaways

• Study projects 2.1 bn gallons SAF annually by 2030, below 3 bn goal
• HEFA pathway dominates U.S. SAF output, limited by feedstock availability
• Many projects favor renewable diesel over SAF due to current incentives
• Historical project delays suggest actual SAF capacity may lag optimistic forecasts

Pulse Analysis

Sustainable aviation fuel has become a cornerstone of the U.S. strategy to decarbonize air travel, with the Biden administration setting a 3 billion‑gallon annual target for 2030. The Washington State University‑led study provides a data‑driven reality check, analyzing every publicly announced renewable‑fuel project to gauge realistic output. By focusing on construction schedules, operational start dates, and feedstock pipelines, the researchers paint a pragmatic picture that diverges from the more optimistic industry forecasts often cited in policy circles.

The study underscores that hydroprocessed esters and fatty acids (HEFA) will account for the bulk of U.S. SAF production. HEFA relies on fats, oils, and greases—most notably used cooking oil and animal fats—yet the available supply of these feedstocks is finite. As a result, the projected 2.1 billion gallons falls well short of the 3 billion‑gallon goal. Moreover, current tax credits and renewable fuel standards make renewable diesel financially more attractive for many producers, diverting capital away from aviation‑grade fuels. This incentive misalignment could further suppress SAF volumes unless policy adjustments specifically favor aviation pathways.

For investors and policymakers, the findings signal that achieving the 2030 SAF target will require more than simply counting announced projects. Accelerated feedstock development, targeted subsidies for aviation fuel, and streamlined permitting processes are essential to bridge the gap. Companies that can secure reliable, low‑cost feedstock streams or innovate beyond HEFA—such as with alcohol‑to‑jet or power‑to‑liquid technologies—may capture a competitive edge. Ultimately, aligning market incentives with the broader climate agenda will be critical to turning the SAF vision into measurable emissions reductions.
