Hydrotreated Esters & Fatty Acids Sustainable Aviation Fuel Market - Global Forecast 2026-2032

The Hydrotreated Esters & Fatty Acids Sustainable Aviation Fuel Market size was estimated at USD 1.23 billion in 2025 and expected to reach USD 1.47 billion in 2026, at a CAGR of 19.09% to reach USD 4.20 billion by 2032.

In recent years, the aviation industry has confronted mounting pressure to reduce carbon emissions and achieve net-zero targets by mid-century. Sustainable aviation fuel (SAF) has emerged as the most viable near-term solution, with hydrotreated esters and fatty acids (HEFA) technology leading the charge as the commercially mature pathway. According to the International Air Transport Association, HEFA is projected to represent the majority share of SAF production through the end of the decade, owing to its compatibility with existing engines and infrastructure.

Global policy frameworks have reinforced the imperative for sustainable fuel adoption, with the European Union mandating a minimum 2 percent blend of SAF by 2025 and planning successive increases to support carbon reduction goals. At the same time, government incentives and credits, particularly in North America, have created a supportive environment for HEFA production, encouraging investment in feedstock collection, refining capacity, and distribution networks to meet growing airline requirements.

Policy developments and regulatory mandates have redefined the HEFA SAF landscape, creating a ripple effect across the value chain. In the United States, incentives under the Inflation Reduction Act and the Renewable Fuel Standard have provided long-term support mechanisms for producers, while the European ReFuelEU aviation regulation fosters progressive blending requirements. Asian markets are following suit, as Chinese biofuel firms invest over $1 billion in waste-to-SAF plants in anticipation of mandated blending rules. These government-led shifts are transforming previously fragmented demand into robust pipelines for HEFA projects.

Simultaneously, production capacity is expanding at an unprecedented rate. Major refiners have repurposed legacy assets to integrate HEFA processing units, with Phillips 66’s Rodeo refinery completing a 10,000 barrels-per-day SAF conversion and Diamond Green Diesel commissioning a 15,000 barrels-per-day facility in Texas. Smaller-scale operations in Nevada and Hawaii are further illustrating how new entrants can leverage localized feedstock supplies and streamlined permitting to contribute to overall volume growth.

Beyond HEFA, strategic diversification is underway as stakeholders explore complementary technologies such as alcohol-to-jet and Fischer–Tropsch pathways. As of April 2025, non-HEFA solutions comprised over a quarter of the global SAF project pipeline, signaling an industry pivot towards feedstock resiliency and technological plurality.

In 2025, the United States implemented comprehensive tariffs on imported biofuel feedstocks and industrial equipment, generating pronounced cost pressures for SAF producers. These levies, targeting materials from palm fatty acid distillates to refining machinery, increased operational expenses and hindered project economics. Industry reports highlight that several biodiesel and renewable diesel facilities curtailed production amid uncertainty over subsidy programs and trade policy. Concurrently, Europe’s largest biofuels producer warned of margin compression due to U.S. levies that disrupted its North American feedstock sourcing strategies.

A landmark ruling by the U.S. Court of International Trade challenged the legality of emergency tariffs, offering potential relief for importers of key feedstocks if the decision withstands appeal. However, the lingering threat of renewed trade actions continues to inject volatility into supply chain planning and capital allocation for SAF projects.

These cost fluctuations have also deterred airlines from locking in long-term SAF purchase agreements, exacerbating the industry’s struggle to secure predictable demand. Airlines and energy companies remain at an impasse over pricing and supply commitments, slowing the pace of contractual off-take deals critical to achieving decarbonization objectives.

The HEFA SAF market exhibits distinct dynamics across multiple segmentation axes that collectively shape investment and operational strategies. Feedstock options span advanced algal oils alongside traditional lipid streams such as vegetable oils, animal fats, and waste oils. Producers fine-tune operations to extract optimal yields from poultry and tallow fractions within the animal fat category, while vegetable oil inputs leverage canola, palm, and soybean sources to balance cost efficiency and sustainability criteria.

Application-based segmentation further underscores divergent demand signals, as commercial aviation’s cargo divisions, legacy networks, and low-cost carriers pursue differentiated blending approaches to meet regulatory thresholds and brand commitments. Military aviation programs reinforce strategic long-term offtake agreements, and private and business aviation not only drive early adoption but also showcase high-ratio and pure SAF flights to highlight environmental leadership.

Aircraft type segmentation introduces an additional layer of complexity, where high-utilization freighters prioritize robust supply chains for elevated blend ratios, regional and narrow-body platforms calibrate fuel choices to balance route economics, and wide-body fleets navigate large-volume contracts. Blending ratio segmentation-from modest ten percent blends to ambitious half-and-half mixes-enables tailoring decarbonization trajectories, while off-site and on-site blending channels define the logistical frameworks that integrate HEFA SAF into existing refueling infrastructure.

In the Americas, a confluence of federal and state incentives under programs such as the Renewable Fuel Standard and Low Carbon Fuel Standard has catalyzed HEFA SAF deployment. North America now claims over thirty-four percent of the global SAF project pipeline, with significant capacity additions in California and Texas driven by legacy refinery conversions and new partnerships between airlines and feedstock suppliers.

Within Europe, the Middle East, and Africa, stringent sustainability mandates under ReFuelEU aviation and emerging UK blending requirements are reshaping feedstock eligibility, enforcing rigorous certification standards, and stimulating investments in innovative waste-based supply chains. These regulatory imperatives, coupled with regional maritime fuel rules, are forging interconnected markets for HEFA SAF that extend beyond aviation into port and shipping operations.

Across the Asia-Pacific region, substantial capital commitments by Chinese biofuel firms to convert used cooking oil into jet fuel anticipate forthcoming blending mandates, while Southeast Asian nations leverage abundant palm oil reserves to explore domestic HEFA capacity. Although representing nearly a quarter of global SAF projects, Asia-Pacific stakeholders must address feedstock competition and sustainability concerns to realize the full potential of their production pipelines.

Leading producers have demonstrated strategic agility, as evidenced by Neste’s record sustainable aviation fuel volumes and expanded Rotterdam refining capacity, which drove an eighty percent quarter-on-quarter increase in SAF sales and lifted comparable EBITDA by over forty percent despite a slight margin contraction.

World Energy has strengthened its market position through high-profile partnerships and technical demonstrations, securing a multi-year sustainable aviation fuel certificate agreement with a global consulting firm and enabling the world’s first transatlantic flight powered solely by HEFA SAF, showcasing the fuel’s operational viability and environmental benefits at scale.

In the United States, refiners such as Phillips 66, Diamond Green Diesel, New Rise Renewables, and Par Pacific have commissioned new HEFA facilities, repurposing legacy infrastructure to process agricultural and waste lipids into drop-in jet fuel that can be blended up to fifty percent with conventional kerosene.

Industry leaders should prioritize diversification of feedstock portfolios by engaging with both traditional lipid sources and emerging options such as algae oils, ensuring resilience against supply constraints and volatility. Strengthening partnerships with agricultural cooperatives, waste collection networks, and technology innovators will foster integrated supply ecosystems capable of delivering consistent feedstock quality and volume.

To navigate regulatory complexity, companies must actively engage in policy dialogues and advocate for clear, stable mandates that align economic incentives with decarbonization goals. Implementing traceability solutions-such as blockchain-enabled book-and-claim systems-will enhance transparency, support sustainability credentials, and build stakeholder confidence across the value chain. Governments can further accelerate progress by phasing out fossil fuel production subsidies and channeling resources into strategic SAF production incentives, as called for by the International Air Transport Association.

Finally, investing in downstream infrastructure for both off-site and on-site blending platforms will be critical to streamline logistics, reduce blending costs, and broaden access to higher-ratio SAF blends. Collaboration across airlines, refiners, and airport operators to establish robust distribution networks is essential to meet evolving blending targets and sustain the industry’s trajectory toward net-zero emissions.
