The ASTM D4054 Qualification Process and Its Significance
The ASTM D4054 process is the definitive industry standard for evaluating and qualifying new aviation fuels. Managed by ASTM International’s Committee D02.J0.06, the process involves rigorous multi-tiered testing to ensure that alternative fuels meet the same safety and performance standards as petroleum-based jet fuel. Acceptance into the D4054 Clearinghouse signals that a candidate fuel has demonstrated strong potential for full qualification and commercial use.
According to Dr. Zachary West, Director of the D4054 Clearinghouse, “We accept candidate fuels into the D4054 Clearinghouse that show strong potential for completing the ASTM qualification process successfully.” This validation is crucial for UFT, as only nine biofuel pathways have completed the process to date. The Clearinghouse, established by the FAA’s ASCENT program, provides a collaborative framework involving academia, industry, and regulators to advance SAF technologies.
The qualification process comprises pre-qualification, followed by detailed Tier 1 and Tier 2 testing. These phases assess fuel properties, engine compatibility, safety, and environmental benefits. The Commercial Aviation Alternative Fuels Initiative (CAAFI) notes that this process can be resource-intensive, but recent efforts aim to streamline qualification to accelerate SAF adoption and reduce capital barriers.
“This marks a significant milestone for Universal Fuel Technologies towards their goal of commercial acceptance.” — Dr. Zachary West, D4054 Clearinghouse
Universal Fuel Technologies’ Flexiforming Technology
UFT’s Flexiforming technology is a single-stage, all gas-phase process using zeolite catalysts at moderate pressure and temperature. The process can convert a wide range of alcohol feedstocks, including ethanol and methanol, into SAF, as well as upgrade renewable naphtha and LPG into high-value aromatic fuels. Over 500 pilot plant tests on 50 feedstocks demonstrate its versatility and operational stability.
The technology’s key differentiator lies in its energy and hydrogen efficiency: it uses 75% less energy and 33% less hydrogen than conventional ethanol-to-jet processes. This translates into production costs up to 50% lower than current methods, directly addressing one of the industry’s main barriers to broader SAF adoption. Flexiforming can also upgrade naphtha byproducts from existing SAF processes into high-value aromatic SAF, enabling higher blend ratios and potentially 100% drop-in use in commercial aircraft.
CEO Alexei Beltyukov stated, “The acceptance into the D4054 Clearinghouse is an important validation of our Flexiforming technology and significantly derisks our road to approval for commercial use.” UFT’s pilot project at RPD Technologies in Texas produced nearly 100 liters of SAF samples, including both synthetic aromatic kerosene (SAK) and fully synthetic drop-in fuels, underlining the process’s readiness for scale-up and further qualification.
Economic and Technical Impact
Flexiforming’s cost and energy advantages could shift the economics of SAF production. By reducing reliance on expensive hydrogen and minimizing energy input, the technology may lower the price gap between SAF and conventional jet fuel. This is particularly important as current SAF production costs, depending on the pathway, can range from around €0.88 to €3.44 per liter in Europe, according to EU research.
The process’s flexibility in feedstock and output also allows producers to adapt to changing market conditions and maximize revenue streams. Its compatibility with existing infrastructure and ability to upgrade byproducts from other SAF processes further enhance its commercial appeal.
UFT’s intellectual property portfolio includes more than 30 patents across 14 countries, providing broad protection for its core technology and supporting future commercialization efforts.
Market Context and Industry Growth Projections
The SAF market is poised for substantial growth due to regulatory mandates, airline commitments, and increasing consumer awareness of aviation’s climate impact. North-America currently leads in SAF adoption, supported by policy initiatives such as the U.S. Sustainable Aviation Fuel Grand Challenge, which sets ambitious production targets for 2030 and 2050.
Market research from Precedence Research forecasts U.S. SAF market growth from USD 450.41 million in 2024 to USD 43.17 billion by 2034. The Asia-Pacific region is expected to see the fastest growth, exceeding 60% CAGR, reflecting rapid aviation expansion and environmental policy developments in emerging economies.
The availability of diverse, non-food biomass feedstocks, including waste oils, municipal waste, and cellulosic materials, supports the scaling of SAF production. However, feedstock competition and supply chain development remain challenges, as SAF must not compete with food crops or contribute to deforestation.
“Achieving net-zero aviation emissions by 2050 requires SAF to supply 10-15% of final jet fuel demand by 2030, a five- to six-fold increase in project pipeline.” — Mission Possible Partnership
Recent Developments and Industry Response
UFT’s acceptance into the ASTM D4054 Clearinghouse follows a series of technical and commercial milestones, including a five-month pilot campaign and a $3 million seed funding round led by TO VC and Alchemist Accelerator. The company’s collaboration with Washington State University’s Bioproducts, Sciences, and Engineering Lab, an authority in SAF research, adds credibility to its technical validation process.
Industry experts view UFT’s progress as a sign of the sector’s maturation. Dr. West and others have highlighted the selectivity of the Clearinghouse process and the importance of technical credibility. UFT’s leadership emphasizes that their SAF “can meet the toughest performance standards without sacrificing scalability or quality.”
Looking ahead, UFT plans to produce larger fuel samples for Tier 1 and Tier 2 testing, aiming for initial ASTM qualification as a blend component by the end of 2026. Achieving full 100% drop-in certification would further expand market opportunities, especially as airlines and regulators seek higher blend ratios for SAF.
Policy and Regulatory Environment
Government policy is a key driver of SAF market expansion. The U.S. Sustainable Aviation Fuel Grand Challenge sets clear targets for production and emissions reduction, while the FAA’s ASCENT program coordinates research and qualification efforts. The FAA has invested over $13 million in SAF R&D since 2014, and recent grants support regional supply chain development across five U.S. universities.
IATA and other industry bodies advocate for harmonized, technology-neutral policies that combine mandates with incentives to accelerate SAF deployment. The European Union’s policy framework supports alternative jet fuel development, with research showing wide variation in production costs and carbon abatement potential across technologies.
The ASTM qualification process remains the technical foundation for SAF adoption, requiring active industry collaboration and rigorous performance testing to ensure safety and compatibility with commercial aviation operations.
Challenges and Competitive Landscape
Despite rapid progress, the SAF industry faces significant hurdles. Scaling production to meet 2030 and 2050 targets requires massive investment and technology deployment. High production costs, feedstock competition, and supply chain logistics remain key barriers. The current global SAF output is a fraction of what will be required to achieve net-zero ambitions.
The competitive landscape includes nine certified SAF production pathways, each with distinct advantages and limitations. New entrants like UFT must demonstrate not only technical performance but also cost competitiveness and supply chain integration. Infrastructure compatibility is essential, as SAF must be seamlessly integrated into existing airport fueling systems and airline operations.
The ASTM D4054 process itself is lengthy and resource-intensive, requiring sustained technical and financial commitment. UFT’s progress through the Clearinghouse is a major step, but further testing and validation are needed before full commercial qualification is achieved.
Future Outlook and Implications
The convergence of technological innovation, policy support, and market demand creates strong momentum for SAF deployment. UFT’s Flexiforming technology, with its cost and energy advantages, is well-positioned to capitalize on market growth, especially as regulatory and airline demand for SAF intensifies.
Successful qualification and commercialization of Flexiforming could catalyze broader adoption of SAF, helping the aviation industry meet its decarbonization targets. The ability to upgrade byproducts and adapt to multiple feedstocks adds resilience and flexibility, supporting the development of a robust, diversified SAF supply chain. However, continued innovation, investment, and cross-sector collaboration will be essential to overcoming remaining barriers and achieving the scale required for meaningful climate impact.

SABA Members Back Infinium eSAF Facility With Long-Term Deals
Google, McKinsey, and others sign binding SAFc agreements to support Infinium Energy’s 100,000 MT/year Texas eSAF project.
Corporate members of the Sustainable Aviation Buyers Alliance (SABA) have signed binding, multi-year agreements to purchase sustainable aviation fuel certificates (SAFc) from Infinium Energy’s planned electro-sustainable aviation fuel (eSAF) facility in Texas. The commitments, announced on September 22, 2026, are designed to provide the financial demand signals necessary for Infinium to reach a final investment decision on the project.
In a press release issued by SABA, the organization confirmed that American Airlines (AA) will serve as the physical offtaker for the fuel, managing logistics and delivery. The corporate buyers purchasing the associated certificates include AVEVA, Bain & Company, Google, and McKinsey & Company. The agreement marks the first time SABA’s procurement model has been utilized to directly drive new production capacity for scalable sustainable aviation fuel.
Project Atlas production and environmental targets
Infinium Energy was selected through a SABA procurement process earlier in 2026 to provide ultra-low carbon eSAF. The fuel is produced using waste carbon dioxide and renewable energy, distinguishing it from traditional biofuel pathways that rely on agricultural or waste feedstocks.
The planned Texas facility, designated Project Atlas, is expected to have an annual sustainable aviation fuel (SAF) production capacity of 100,000 metric tons. According to the alliance, the contracted volumes will support an expected greenhouse gas abatement of 212,000 metric tons of carbon dioxide equivalent (mtCO2e). SABA equates this emissions reduction to approximately 3,500 commercial flights between John F. Kennedy International Airport (JFK) and Los Angeles International Airport (LAX).
“We’re proud to partner with SABA members including AVEVA, Bain & Company, Google, McKinsey, and others, as well as American Airlines to bring Infinium Energy’s next world scale eSAF facility to life. Their commitment reflects a shared conviction that decarbonizing aviation requires real investment in next-generation supply,” said Robert Schuetzle, CEO of Infinium Energy.
Aggregating demand through book-and-claim
The transaction utilizes a book-and-claim model. Corporate buyers purchase the SAFc to claim the environmental benefits against their business travel emissions, while the physical fuel is delivered to partner airlines. This mechanism allows corporations to fund SAF production even when the physical fuel cannot be delivered directly to the airports their employees use.
American Airlines will manage the physical integration of the eSAF into the commercial aviation fuel supply chain. Jill Blickstein, Chief Sustainability Officer at American Airlines, stated that the corporate commitments broaden participation in the SAF market and demonstrate how customers can collaborate with airlines and fuel producers to advance decarbonization.
SABA, a joint initiative of the Environmental Defense Fund (EDF), the Center for Green Market Activation (GMA), and RMI, has aggregated $500 million in SAFc demand from 35 companies to date. Aviation currently accounts for approximately 2 to 3 percent of global greenhouse gas emissions.
“Novel technologies are critical to meeting future demand for sustainable aviation fuel, but they will not be operational in time without investments made today. This procurement demonstrates how aggregated, long-term demand can help take promising eSAF projects from idea to reality,” said Jon Creyts, CEO of RMI.
AirPro News analysis
We view this agreement as a critical structural step for the eSAF market. Power-to-Liquid (PtL) fuels like those planned for Project Atlas face a steep commercialization barrier. They are highly capital-intensive to build and currently produce fuel at a significant cost premium compared to both conventional Jet A and HEFA-based SAF derived from waste fats and oils.
Airlines operate on thin margins and generally cannot absorb the full green premium of eSAF alone. By unbundling the environmental attributes from the physical fuel, the SABA model allows highly capitalized corporate entities like Google and McKinsey & Company to absorb that premium. More importantly, signing binding, multi-year offtake agreements provides the revenue certainty that infrastructure lenders require before financing first-of-a-kind industrial facilities. If Project Atlas reaches a positive final investment decision based on these contracts, it will validate the book-and-claim model as a viable financing mechanism for next-generation aerospace infrastructure.

EU Exceeds 2025 SAF Mandate at 2.79 Percent Blend Rate
EASA reports EU airports hit 2.79% SAF blend in 2025, surpassing the 2% ReFuelEU mandate with 1.1M tonnes supplied.
The European Union surpassed its initial Sustainable Aviation Fuel (SAF) mandate in 2025, with SAF accounting for 2.79 percent of all jet fuel supplied to EU airports during the first mandatory reporting year.
According to the 2026 ReFuelEU Aviation Annual Technical Report published by the European Union Aviation Safety Agency (EASA) on September 17, 2026, fuel suppliers delivered 1.1 million tonnes of SAF against a total aviation fuel supply of 39.3 million tonnes. The 2.79 percent blend rate comfortably exceeded the 2 percent minimum required by the ReFuelEU regulation for 2025. This uptake resulted in an estimated reduction of 3.77 million tonnes of CO2 equivalent greenhouse gas emissions.
“We are pleased to confirm that the SAF mandate under ReFuelEU Aviation was not only met but exceeded,” EASA Executive Director Florian Guillermet stated in the agency’s press release.
Compliance and distribution across European hubs
The EASA report indicates high compliance rates across the sector. Ninety-three percent of aircraft operators and 90 percent of fuel suppliers fulfilled their reporting obligations in 2025. EASA noted that noncompliance among aircraft operators was primarily limited to small business jet operators, nonscheduled carriers, and third-country operators that failed to respond to competent authorities.
SAF distribution reached 121 Airports across all 27 Member States, representing 79 percent of all Union airports. Uptake was heavily concentrated at major European hubs. Amsterdam Airport Schiphol (AMS) accounted for 29 percent of the tracked SAF supply, followed by Frankfurt Airport (FRA) at 8 percent and Paris Charles de Gaulle Airport (CDG) at 7 percent.
Supply chain dynamics and feedstock dependencies
While the headline blending figures demonstrate regulatory success, the technical report reveals a structural reliance on imported raw materials. Although 86 percent of the SAF supplied at EU airports was refined domestically within the European Union, 85 percent of the underlying feedstocks originated from outside the bloc.
The primary feedstock utilized was Used Cooking Oil (UCO) processed via the Hydroprocessed Esters and Fatty Acids (HEFA) pathway. Of the imported feedstocks, 61 percent originated from China, with additional volumes sourced from Malaysia and Indonesia. On the refining side, Neste’s Rotterdam facility alone produced 33 percent of all European SAF in 2025.
AirPro News analysis
The successful implementation of the 2 percent mandate in 2025 proves that the logistical framework for SAF distribution at major European hubs is functional. However, the heavy reliance on Asian Used Cooking Oil presents a long-term vulnerability for European aviation. As the ReFuelEU mandate scales to 6 percent in 2030, the Regulations will also introduce sub-mandates for synthetic aviation fuels (e-fuels). With approximately 50 synthetic fuel projects awaiting final investment decisions and no large-scale e-fuel facilities currently operational in Europe, we anticipate significant capital mobilization will be required over the next 36 months to prevent future supply bottlenecks and reduce dependency on imported biomass.

Montana Renewables Cuts SAF Expansion Cost to $137M
Calumet’s Montana Renewables targets 200M gallons of SAF annually by 2028 for $137M, down from a $1.2B plan.
Calumet, Inc. and its subsidiary Montana Renewables, LLC announced a revised expansion plan on September 1, 2026, that will scale SAF production to 200 million gallons annually by 2028 for a fraction of the originally projected cost.
By repurposing existing refining equipment at the Great Falls, Montana facility, the company expects to complete the MaxSAF project with only $137 million in remaining capital. This abandons a previous $1.2 billion megaproject design. The pivot eliminates the need for third-party equity and minimizes debt while accelerating domestic sustainable aviation fuel (SAF) capacity.
Capital efficiency and Department of Energy funding
The original Phase 2 plan contemplated $1.2 billion in capital expenditure. The revised strategy captures 70 percent of the expected benefit for 15 percent of the cost. The financial restructuring involves an amended Loan Guarantee Agreement (LGA) with the U.S. Department of Energy (DOE).
The original LGA was executed in January 2025, with a $782 million first tranche funded in February 2025 to recapitalize Montana Renewables, LLC (MRL). Under the amended agreement, the company will make a final draw of $34 million. This is significantly lower than the original $658 million Phase 2 DOE funding limit.
Calumet CEO Todd Borgmann stated the Office of Energy Dominance Financing (EDF) supported the adjustment to the loan agreement.
“Our amended agreement with the DOE facilitates innovative technology and domestic energy security at a fraction of the original cost. EDF’s willingness to right-size the LGA reflects its ongoing support for Montana’s largest agricultural investment. We look forward to our continued collaboration with the DOE on the success of this project,” Borgmann said.
Borgmann credited the company’s engineering and operational teams for developing a project that maximizes output while drastically reducing the required capital investment.
Production timeline and capacity milestones
The Great Falls facility currently operates at a 60 million gallon SAF run-rate following a spring 2026 constraint removal. A scheduled turnaround in the fourth quarter of 2026 will tie in repurposed equipment from the adjacent Calumet Montana Refining facility.
Following the fourth-quarter integration, the company expects to exceed an 80 million gallon SAF run-rate by December 31, 2026. Production is projected to surpass 120 million gallons by spring 2027 and reach the 200 million gallon target by December 31, 2028.
Total renewable product sales, including renewable diesel and renewable gasoline, are targeted at 17,000 barrels per day by year-end 2028. This represents a 40 percent expansion. The expanded facility will consume 2 billion pounds of ranch- and farm-originated feedstocks annually.
AirPro News analysis
The revised MaxSAF expansion highlights a strategic shift in how producers approach SAF scaling. As noted by Aviation Week on September 2, 2026, the plan allows the largest US producer of SAF to more than triple its production capacity for barely 10 percent of the originally planned investment.
During Calumet’s second-quarter 2026 earnings call on August 7, 2026, the company confirmed that Montana Renewables completed performance testing of the newly installed MaxSAF catalyst, which met or exceeded expectations. By leveraging existing fossil-fuel infrastructure rather than pursuing multi-billion-dollar greenfield projects, producers can bring SAF to market faster and with significantly lower financial risk. This capital-efficient model may set a precedent for other refiners looking to enter or expand in the renewable fuels sector without diluting equity or taking on unsustainable debt.
