Delta and Shell Achieve First Commercial Scale SAF Delivery at Portland Airport
Delta, Shell, and Portland International Airport deliver over 400,000 gallons of sustainable aviation fuel, advancing aviation decarbonization efforts.
Delta’s Historic Partnership with Shell and Portland International Airport Marks Milestone in Sustainable Aviation Fuel Deployment
In September 2024, Delta Air Lines, in collaboration with Shell Aviation and Portland International Airport (PDX), achieved a major milestone by delivering over 400,000 gallons of SAF into PDX’s fuel system. This marked the first commercial-scale SAF uplift at the Oregon airport, demonstrating the intricate partnerships and infrastructure investments required to scale sustainable aviation fuel adoption across the United States. The move highlights both the opportunities and challenges of decarbonizing aviation, a sector responsible for a significant share of global carbon emissions. As SAF currently accounts for only about 0.53% of global jet fuel consumption and costs substantially more than conventional fuels, such Partnerships are critical to advancing climate goals and establishing the supply chains needed for industry-wide transformation.
The Delta-Shell-PDX partnership underscores how Airlines, fuel suppliers, and airport authorities can work together to meet ambitious climate targets, even as the aviation industry faces daunting economic and logistical barriers. Their achievement not only sets a precedent for other airports and carriers but also provides a blueprint for integrating SAF into existing fuel systems, an essential step toward reducing aviation’s environmental footprint.
Background and Context of Sustainable Aviation Fuel Development
Sustainable aviation fuel is widely recognized as one of the most promising solutions for decarbonizing commercial aviation, which currently contributes an estimated 2-3% of global greenhouse gas emissions. Unlike ground transportation, where electrification is rapidly advancing, aviation’s unique energy density and weight requirements make SAF a more viable near-term solution. SAF can reduce lifecycle carbon emissions by up to 80% compared to conventional jet fuel, while remaining compatible with existing aircraft engines and airport infrastructure.
According to the International Air Transport Association (IATA), SAF could provide up to 65% of the emissions reductions necessary for aviation to achieve net-zero carbon Emissions by 2050. However, scaling production remains a challenge: global SAF production hit 1 million tonnes in 2024, double the previous year but still far below the projected demand of 1.5 million tonnes. Industry leaders have voiced concerns about the slow pace of progress, with IATA’s Director General Willie Walsh noting that “SAF volumes are increasing, but disappointingly slowly.”
SAF can be produced through nine certified pathways, with the most common method, hydroprocessed esters and fatty acids (HEFA), converting waste oils, fats, and other biomass into jet fuel. Other pathways, such as alcohol-to-jet and synthetic paraffinic kerosene, offer different feedstock options and carbon intensity profiles. The sustainability of SAF hinges on its closed-loop carbon cycle: the CO₂ emitted during combustion is offset by the CO₂ absorbed during feedstock growth, provided the feedstocks and processes are carefully managed.
Delta’s Strategic Approach to Sustainable Aviation Fuel
Delta Air Lines has positioned itself as an industry leader in SAF adoption. In 2021, the airline pledged to use SAF for at least 10% of its fuel by 2030, a commitment that requires procuring over 400 million gallons of SAF annually by the decade’s end. Delta has already secured long-term contracts for 200 million gallons, representing about half of its 2030 goal.
The airline’s focus on SAF is driven by the fact that approximately 90% of its direct (Scope 1) emissions stem from jet fuel. As Delta’s senior vice president of sustainability, Gail Grimmett, explained, “Our Scope 1 is massive. Anything beyond Scope 1 is like a rounding error.” Delta’s SAF usage has grown rapidly, with 3.5 million gallons blended in 2023 and over 13 million gallons delivered in 2024, more than triple the previous year. These efforts have helped Delta avoid approximately 32,000 metric tons of CO₂ emissions from operations at major airports.
Beyond procurement, Delta invests in SAF production infrastructure and policy advocacy. The airline supports a Minnesota production hub benefiting from a $1.50 per gallon state tax credit and participates in industry coalitions to promote favorable SAF policies. Delta’s collaborative approach reflects a broader industry recognition that achieving climate goals requires cooperation rather than competition among airlines.
“This isn’t a competition amongst us. We’ve gotta work together on this.” – Gail Grimmett, Delta Air Lines
The Portland International Airport Partnership Details
The Delta-Shell-PDX partnership stands as a significant step in expanding SAF’s reach in the United States. The Delivery of over 400,000 gallons of blended SAF to PDX in September 2024 marked the airport’s first commercial-scale SAF operation. The fuel was produced in the U.S. from waste-derived feedstock, with Shell supplying the neat SAF to Zenith Terminal in Portland, where it was blended with traditional jet fuel before being delivered to PDX.
This delivery required coordination among multiple stakeholders and leveraged existing infrastructure, demonstrating that SAF can be integrated into conventional fuel systems without major new investments. Delta’s SAF director, Charlotte Lollar, highlighted the importance of collaboration, saying, “Every SAF delivery is a powerful example of how industry collaboration can unlock markets for sustainable aviation fuel.”
The Port of Portland’s support aligns with its broader sustainability commitments. Zenith Energy’s Portland terminal, a key player in the supply chain, has committed to transitioning 100% of its crude oil storage to renewable fuels by 2027. Already, 66% of its storage is dedicated to renewables, making it a leading facility in the region.
Infrastructure, Economics, and Policy Frameworks
Supply Chain and Production Capacity
The SAF supply chain is complex, involving feedstock collection, production, blending, storage, and distribution. Zenith Energy’s Portland terminal has become a key hub, receiving its first SAF shipment from Montana Renewables in June 2023. Montana Renewables is expanding its capacity from 30 million to 300 million gallons annually by 2028, supported by a $1.44 billion U.S. Department of Energy loan. This expansion will double feedstock purchases to 3 billion pounds per year, positioning the facility as a global SAF leader.
Shell Aviation plays an intermediary role, leveraging its logistics expertise to move SAF from production sites to airports. The company aims for 10% of its aviation jet fuel sales to be SAF by 2030, necessitating significant investment in blending and distribution infrastructure.
Book-and-claim systems are emerging to address supply limitations, allowing airlines to purchase the environmental attributes of SAF even when the fuel is not physically delivered to their departure airport. This mechanism supports broader market access and demand for SAF.
“The integration of SAF into established fuel infrastructure demonstrates how sustainable fuels can leverage existing petroleum networks while gradually transforming their composition toward renewables.”
Economic and Regulatory Challenges
SAF remains significantly more expensive than conventional jet fuel, costing 3–5 times as much on average. The cost premium is due to limited scale, feedstock constraints, and higher processing costs. In Europe, additional compliance fees linked to regulatory mandates have further increased prices.
Policy support is crucial for bridging the economic gap. The U.S. federal 45Z Clean Fuel Production Credit, created by the Inflation Reduction Act, provides up to $1.75 per gallon for SAF, with additional incentives at the state level in Minnesota and emerging programs in Illinois, Michigan, and Nebraska. Oregon’s Clean Fuels Program and California’s partnership with Airlines for America are also driving market development.
Internationally, harmonized standards and incentives are essential due to aviation’s global nature. The IATA advocates for technology- and feedstock-neutral policies, with mandates used alongside innovation support and cost-reduction programs. Compliance with schemes like CORSIA adds further financial pressure, reinforcing the need for affordable, high-integrity SAF.
Environmental Benefits and Industry Implications
SAF offers significant environmental advantages beyond CO₂ reduction. It can cut lifecycle greenhouse gas emissions by up to 80% and dramatically reduce particulate and sulfur emissions, improving air quality around airports. The use of waste-derived feedstocks also supports circular economy principles, turning waste oils and fats into valuable fuel.
However, scaling SAF raises questions about feedstock sustainability, land use, and lifecycle impacts. Waste feedstocks provide the greatest carbon benefits but are limited in supply, prompting research into purpose-grown energy crops and synthetic fuels. Robust lifecycle assessments and monitoring are essential to ensure claimed emissions reductions are real and additional.
The shift to domestic SAF production enhances energy security and supports rural economies, especially as recent policy changes require American-controlled production and North American feedstocks. Water management and land use must be carefully considered to avoid unintended consequences as production expands.
Conclusion
The Delta-Shell-Portland partnership for the first commercial-scale SAF uplift at PDX is a landmark in aviation’s transition to Sustainability. It demonstrates the technical, logistical, and collaborative requirements for integrating SAF into existing airport fuel systems and sets a replicable model for other airports and regions. While SAF currently accounts for a small fraction of global jet fuel use, the Portland achievement shows the potential for rapid growth through coordinated investment and policy support.
Looking ahead, scaling SAF will demand continued investment in production capacity, technological innovation to address feedstock and cost challenges, and robust policy frameworks at all levels. The experience gained from early deployments will inform industry best practices and infrastructure planning, supporting the broader goal of aviation decarbonization by 2050. As more airlines, airports, and fuel suppliers join the effort, the foundation is being laid for a sustainable future for air travel.

U.S. Advances Sustainable Aviation Fuel Initiative with 2030 Targets
U.S. agencies collaborate to scale sustainable aviation fuel production to 3 billion gallons by 2030, aiming to cut emissions and boost energy security.
This article is based on an official press release from the U.S. Department of Energy.
U.S. Government Accelerates Sustainable Aviation Fuel Initiative to Meet 2030 Goals
The push to decarbonize the aerospace sector is entering a critical execution phase. Through a formalized Memorandum of Understanding (MOU), the U.S. Department of Energy (DOE), the Department of Transportation (DOT), and the Department of Agriculture (USDA) have united to drive the Sustainable Aviation Fuel (SAF) Initiative. Originally launched in September 2021 as the SAF Grand Challenge, this government-wide effort aims to scale up domestic production, enhance national energy security, and revitalize rural agricultural economies.
Sustainable aviation fuel is a synthesized, “drop-in” hydrocarbon fuel derived from renewable or waste materials rather than traditional petroleum. Because it requires no modifications to existing aircraft engines or fueling infrastructure, federal agencies and industry leaders view it as the most viable near-term solution for reducing aviation emissions. According to the DOE, the initiative targets a minimum 50% reduction in lifecycle greenhouse gas emissions compared to conventional jet fuel.
As we move through 2026, the transition from foundational planning to active infrastructure expansion is well underway. With ambitious production targets looming at the end of the decade, the coordinated federal strategy is deploying hundreds of millions in grant funding to bridge the gap between current supply and future demand.
Core Objectives and Federal Investments
Time-Bound Production Targets
The SAF Initiative is anchored by two primary production milestones. According to official DOE and DOT frameworks, the near-term objective is to scale domestic SAF production to 3 billion gallons per year by 2030. Looking further ahead, the long-term goal is to produce enough SAF to meet 100% of domestic aviation fuel demand by 2050, a figure the agencies estimate will reach approximately 35 billion gallons annually.
Biomass Potential and Feedstock Diversity
To meet these massive volume requirements, the initiative relies on a diverse array of approved feedstocks, including corn grain, oil seeds, forestry residues, municipal solid waste, and agricultural byproducts. Data from the DOE’s 2023 Billion-Ton Report indicates that the United States possesses the capacity to triple its biomass production to over 1 billion tons per year. The DOE projects that this volume could yield an estimated 60 billion gallons of liquid biofuels, providing more than enough raw material to satisfy the 2050 aviation demand projections.
Infrastructure and Grant Funding
Federal financial backing has been crucial to moving these targets from paper to production. In January 2025, the Federal Aviation Administration (FAA) announced $249 million in grants through the Fueling Aviation’s Sustainable Transition (FAST) program. This capital injection, funded by a $297 million appropriation to the DOT under the Inflation Reduction Act, is specifically earmarked for domestic SAF production, transportation, and storage infrastructure.
These investments are already yielding tangible geographic expansions. Historically, U.S. SAF supply networks were heavily concentrated on the West Coast. However, federal progress reports note that by early 2025, new supply terminals successfully reached the U.S. East Coast, significantly broadening access for commercial and private aviation hubs nationwide.
“Over the past three years, as this Department has worked alongside our partners in the administration and in the private sector, we’ve made measurable progress in reducing emissions and making our skies cleaner while also growing the economy and creating good-paying jobs.”
Commercial Adoption and Global Context
Airlines Ramp Up Utilization
Commercial airlines are the ultimate end-users of this federal push, and recent data shows a marked increase in adoption, despite ongoing supply constraints. In April 2026, Delta Air Lines reported consuming 23.4 million gallons of SAF throughout 2025. According to the airline’s sustainability disclosures, this represents an 80% increase from the 13 million gallons utilized in 2024.
“Delta’s goal of using 10% SAF by 2030 remains real. Every day, we’re working across our business, industry and the SAF value chain for meaningful impact – and we’re making solid progress.”
International Regulatory Momentum
The U.S. SAF Initiative does not exist in a vacuum; it operates alongside tightening global regulations. In 2025, the European Union’s ReFuelEU Aviation mandate took effect, legally requiring fuel suppliers to blend a minimum percentage of SAF at EU airports. Concurrently, the International Civil Aviation Organization (ICAO) has established a global framework targeting a 5% reduction in the carbon intensity of international aviation fuels by 2030. These international pressures ensure that U.S. airlines operating globally must secure reliable SAF supply chains to remain compliant.
AirPro News analysis
We observe that the narrative surrounding the SAF Initiative has fundamentally shifted over the past two years. While the 2021 Grand Challenge was primarily framed around climate goals and decarbonization, the 2026 landscape, highlighted by reports like the World Economic Forum’s Global Aviation Sustainability Outlook 2026, positions SAF equally as a matter of national energy security. By utilizing domestic agricultural and municipal waste, the U.S. is actively attempting to insulate its aviation sector from volatile foreign oil markets.
However, significant hurdles remain. While Delta’s 80% year-over-year usage increase is commendable, 23.4 million gallons is a drop in the bucket compared to the 3-billion-gallon target set for 2030. The January 2025 SAF Grand Challenge Progress Report and the November 2024 Roadmap Implementation Framework both acknowledge persistent gaps in technology scaling and supply chain logistics. For the DOE, DOT, and USDA, the next four years will be a race against time to ensure that feedstock processing and refinery capacities can match the aggressive timelines they have mandated.

AeroDelft Conducts First Hydrogen Aircraft Taxi Tests in Netherlands
AeroDelft’s student team completed the first hydrogen-powered aircraft taxi tests at Rotterdam The Hague Airport, advancing sustainable aviation.
This article is based on an official press release from AeroDelft.
In late May 2026, the student-led engineering team AeroDelft achieved a significant milestone in sustainability aviation. According to an official press release from the organization, the team successfully conducted the first-ever taxi tests of a hydrogen-powered aircraft at an operational airport in the Netherlands. The tests took place at Rotterdam The Hague Airport (RTHA) and represent a critical transition from laboratory research to real-world application.
The comprehensive testing phase included hydrogen refueling operations, powertrain evaluations, and active taxi tests using gaseous hydrogen. By executing these procedures in a live commercial airport environment, AeroDelft and its partners gathered essential data on both the aircraft’s technological performance and the operational protocols required to safely handle hydrogen on an active tarmac.
This achievement is the culmination of extensive engineering and preparation. As noted in the team’s announcement, bringing a hydrogen aircraft to an operational airport required rigorous safety analyses, detailed operational planning, and close collaboration among multiple aviation and energy stakeholders.
Advancing Project Phoenix
From Laboratory to Tarmac
AeroDelft, a non-profit foundation run entirely by Delft University of Technology (TU Delft) students, has been developing “Project Phoenix” since 2018. According to supplementary research data, the initiative focuses on converting a Sling 4 airframe into a manned hydrogen-electric aircraft. Industry research highlights that in May 2025, AeroDelft became the first student team globally to test a full liquid hydrogen propulsion system in a lab setting, working alongside the Netherlands Organization for Applied Scientific Research (TNO).
Safety and Operational Planning
Operating an experimental aircraft at a commercial facility demands strict safety measures. According to project data, AeroDelft developed comprehensive risk analyses and an operational taxi test plan. This was achieved in close collaboration with research test pilots Alexander in ‘t Veld and Hans Mulder from TU Delft’s Flight Test Laboratory, ensuring that the live tests at RTHA’s Fieldlab Next Aviation facility met stringent aviation safety standards.
Technical Specifications and Infrastructure
Gaseous vs. Liquid Hydrogen
The recent taxi tests utilized gaseous hydrogen. While AeroDelft’s ultimate objective is to achieve flight using liquid hydrogen, gaseous hydrogen was selected for this phase due to its current technological maturity. Based on technical specifications provided in the research report, the single-seat converted aircraft uses a hydrogen fuel cell that combines hydrogen and oxygen to generate electricity, emitting only water. With a full tank of gaseous hydrogen, the aircraft is projected to have an endurance of approximately 40 minutes.
Transitioning to liquid hydrogen remains the next major technical hurdle. Because liquid hydrogen offers a significantly higher energy density by mass and volume, the team projects that utilizing liquid fuel will extend the aircraft’s flight endurance to approximately two hours. To achieve this, future development will require the integration of a cryogenic storage tank capable of maintaining temperatures at -253 °C, along with a complex distribution system.
The DutcH₂ Aviation Hub
The successful test campaign was facilitated by the DutcH₂ Aviation Hub, a collaborative ecosystem coordinated by the Rotterdam The Hague Innovation Airport (RHIA) Foundation and funded by the City of Rotterdam. The AeroDelft press release explicitly thanked partners including TU Delft Aerospace Engineering, RTHA, RHIA, and Air Products Benelux for their roles in turning months of preparation into a successful live test.
Perspectives on Sustainable Aviation
The transition to zero-emission aviation requires proving that new technologies are viable outside of controlled environments. Isha Moharir, Team Manager at AeroDelft, emphasized the importance of real-world testing in public remarks cited by industry reports:
“We want to demonstrate that flying on hydrogen works and that it’s safe in the air and at the airport… We are making absolutely no concessions on safety.”
Moharir further noted that testing at an operational commercial airport yields invaluable insights into the practical steps needed for sustainable aviation. Similarly, Daan van Dijk, an innovator at Rotterdam The Hague Airport, stated that these tests demonstrate tangible progress. According to research summaries, van Dijk highlighted that testing at an active airport is the exact method by which the aviation industry will learn to safely scale hydrogen-powered flight.
AirPro News analysis
We observe that while much of the aerospace sector’s attention has been focused on the in-flight capabilities of hydrogen aircraft, the logistical realities on the ground present an equally formidable challenge. The AeroDelft taxi tests at Rotterdam The Hague Airport serve as a crucial proof-of-concept for bridging the infrastructure gap. Traditional airports are optimized for kerosene; introducing hydrogen requires entirely new storage facilities, mobile refuelers, and emergency response protocols.
Furthermore, the broader hydrogen aviation race is accelerating. While battery-electric aviation propulsion shows promise for short-haul routes, the prohibitive weight of current battery technology limits its application for commercial passenger aviation. Liquid hydrogen presents a highly competitive alternative for longer ranges, provided that the cryogenic and logistical challenges, which initiatives like Project Phoenix are actively addressing, can be resolved at scale.

A standout feature of this collaboration is CGF’s decentralized production model. Rather than relying on traditional, centralized mega-refineries, modular SAF production units will be deployed directly across Loganair’s primary operational network, which includes the Scottish Highlands, Islands, and other regional UK routes.
A Decentralized Approach to Sustainable Aviation Fuel
The partnership relies on highly innovative fuel production technology. ClimaHtech Green Flight, a wholly owned subsidiary of Belfast-based clean energy engineering company CATAGEN, will supply Loganair with fuel produced via two advanced pathways: BioSAF (Power-Biomass-to-Liquid) and eSAF (Power-to-Liquid).
According to the provided technical details, CGF utilizes patented modular reactor technology, specifically the BIOHGEN and E-FUEL GEN systems developed by CATAGEN. This electrically driven platform can operate alongside intermittent renewable power assets and utilize waste biomass feedstocks. Each modular unit is capable of producing 1 million liters of SAF per year, delivering an estimated 90% reduction in well-to-wing carbon emissions compared to conventional fossil jet fuel.
Overcoming Regional Logistics Challenges
As a regional carrier, Loganair operates numerous routes that serve as essential lifelines for remote communities rather than luxury travel destinations. Decarbonizing these short-haul flights presents unique logistical challenges. By deploying production infrastructure close to the point of consumption across Northern Ireland and Scotland, the decentralized model eliminates the need to ship fuel from a distant central hub, thereby reducing both transportation costs and associated carbon emissions.
Regulatory Pressures and Industry Context
The agreement is heavily driven by the current regulatory landscape in the United Kingdom. The UK SAF mandate officially entered into force on January 1, 2025. The mandate requires jet fuel suppliers to blend alternative aviation fuel into conventional aviation fuel at increasing concentrations. The requirement started at 2% in 2025, will rise to 10% by 2030, and is set to reach 22% by 2040. Securing a 15-year supply helps Loganair ensure compliance and avoid potential future market shortages.
ClimaHtech Green Flight, launched in September 2025 at CATAGEN’s Titanic Quarter Campus in Belfast, was created to disrupt the SAF market using off-grid renewable and low-carbon electricity sources. The company has already secured strategic partnerships and offtake agreements with other major industry players, including Ryanair and Shell Aviation Ireland Limited.
Executive Perspectives
Company leadership emphasized the importance of localizing fuel production to support regional connectivity.
“As the UK’s largest regional airline, Loganair plays a vital role in connecting communities across the UK, particularly in areas where aviation is a lifeline rather than a luxury. Decarbonising regional aviation is therefore both a responsibility and a practical challenge. This long-term agreement with ClimaHtech Green Flight is an important step in securing access to Sustainable Aviation Fuel that is produced closer to where we operate, supports UK supply chains, and reflects our commitment to lower our carbon footprint.”
“This offtake agreement with Loganair demonstrates strong airline confidence in our SAF pathways and our ambition to build a distributed, regional SAF production model.”
AirPro News analysis
We view this agreement as a critical indicator of how regional airlines are adapting to stringent environmental mandates. A major hurdle for SAF adoption globally has been the cost and carbon footprint of transporting the fuel from centralized refineries to regional airports. CGF’s decentralized model could serve as a blueprint for regional airlines worldwide, solving the logistics bottleneck that often plagues smaller carriers.
Furthermore, by utilizing local waste biomass and renewable energy, the UK aviation sector can reduce its reliance on imported fuels. This aligns with broader national energy security goals. With the UK SAF mandate now active, airlines are in a race to secure affordable SAF. Early movers like Loganair are locking in long-term Contracts to avoid the anticipated price spikes as the mandate percentages increase toward 2030.
