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.

Germany Awards €350M Grant for Largest Sustainable Aviation Fuel Plant

Germany funds Brandenburg eSAF project with €350M grant to build the largest sustainable aviation fuel facility at Schwedt, aiming for 2030 production.

Published

on

This article is based on an official press release from ENERTRAG and ZAFFRA.

The German federal government and the state of Brandenburg have officially awarded a €350 million grant to the “Brandenburg eSAF” project, marking a significant milestone in the development of sustainable aviation fuels (eSAF). According to a joint press release from ENERTRAG and ZAFFRA, the funding will support the construction of Germany’s largest industrial-scale eSAF production facility at the PCK refinery in Schwedt.

The project, previously known as “Concrete Chemicals,” represents a total investment exceeding €500 million. The facility is being developed by renewable energy company ENERTRAG and eSAF specialist ZAFFRA, a joint venture between Danish clean energy technology firm Topsoe and South African chemicals and energy group Sasol.

Once operational, the plant is designed to cover approximately 25 percent of Germany’s national eSAF blending obligation under the European Union’s ReFuelEU Aviation Regulation. The grant, which includes €245 million from the federal government and €104 million from Brandenburg, is the largest public funding award for a Power-to-Liquid project in Europe to date, according to the official release.

Scaling Up Sustainable Aviation Fuel

The Brandenburg eSAF facility aims to produce more than 30,000 tonnes of sustainable aviation fuel annually starting in 2030. The production process relies on green hydrogen generated through electrolysis powered by renewable electricity, combined with biogenic carbon dioxide.

Innovative Power-to-Liquid Process

According to the project partners, the biogenic CO2 will be supplied by LEIPA Georg Leinfelder, a local paper manufacturer in Schwedt. The green hydrogen will primarily be sourced via the H2 core network, specifically Gascade’s FLOW pipeline, supplemented by an on-site electrolysis plant. These feedstocks are then converted into eSAF using a Fischer-Tropsch synthesis process provided by ZAFFRA’s G2L eFuels platform.

The resulting fuel is expected to deliver lifecycle greenhouse gas reductions of more than 90 percent compared to conventional kerosene. The press release notes that the fuel is ASTM-certified for immediate use in existing aircraft infrastructure.

Regional Investment and Job Creation

Beyond its environmental goals, the Brandenburg eSAF project is positioned as a key driver for regional economic development and European energy security. By producing liquid fuel domestically using local renewable electricity, the initiative aims to reduce the aviation sector’s reliance on imported fossil fuels.

Securing the Industrial Future of Schwedt

The facility is projected to create approximately 150 permanent skilled jobs at the Schwedt site, along with up to 1,500 jobs during the construction phase. This investment is intended to reinforce the PCK refinery’s role in the local economy as it transitions toward a low-carbon model.

“Brandenburg eSAF brings together what belongs together: renewable energy from the region, Schwedt’s industrial heritage, and clear political commitment from federal and state governments. The result is a fuel that makes aviation climate-neutral and secures skilled jobs in the Uckermark region,” stated Dr. Gunar Hering, CEO of ENERTRAG, in the press release.

Engineering studies for the project are currently underway, led by the Griesemann Group, which was appointed in April 2026. The partners are targeting a Final Investment Decision (FID) by the end of 2027, with production scheduled to commence in 2030.

Clean Planet Launches Pilot Facility Converting Plastic Waste to Aviation Fuel

Clean Planet Technologies opens a UK pilot facility converting non-recyclable plastic waste into Sustainable Aviation Fuel, reducing emissions by over 70%.

Published

on

This article is based on an official press release from Clean Planet Technologies.

A major breakthrough in tackling both waste plastic and aviation emissions has been marked with the opening of the world’s first waste plastics to SAF (SAF) pilot facility. Operated by Clean Planet Technologies, the new Sustainability Innovation Centre is located at Discovery Park in Sandwich, Kent. The facility is dedicated to researching and developing new technologies to process non-recyclable plastic waste, beginning with its conversion into jet fuel.

The pilot facility addresses the growing problem of hard-to-recycle waste plastics and the environmental impact of the aviation industry. According to the company’s press release, the UK alone creates 5 million tonnes of waste plastics each year, 80% of which cannot be recycled and is treated as waste. Meanwhile, the world’s commercial aircraft consume 7 to 8 million barrels of jet fuel a day, with less than 1% currently produced from sustainable sources.

Transforming Waste into Sustainable Aviation Fuel

The new pilot facility integrates several stages into a single, controlled system optimized to transform hard-to-recycle plastics into SAF. The process begins with shredding the waste plastics to a uniform size, followed by pyrolysis, where the material is thermocatalytically converted into a synthetic crude oil in an oxygen-free environment. This melts the plastic rather than burning it.

After purification to remove impurities and contaminants, the pyrolysis oil undergoes distillation to separate it into relevant fractions. These fractions are then processed through Clean Planet Technologies’ patented hydroprocessing system, which uses hydrogen to further remove impurities and transform the properties of the product to meet stringent SAF specifications. The resulting ultra-clean, ultra-low sulfur fuel is sent for testing, blending, and evaluation as part of the American Society for Testing and Materials (ASTM) qualification pathway.

Reducing the Aviation Industry’s Carbon Footprint

The environmental impact of this technology are significant. According to Clean Planet Technologies, the process cuts lifecycle greenhouse gas emissions by more than 70% compared to traditional fossil jet fuel.

“Our process first heats the waste plastic with a chemical reaction to turn it into a liquid, rather than burning it. This is then treated with our patented process to remove impurities and create SAF that meets stringent commercial aviation specifications,” said Dr. Andrew Odjo, Chief Executive Officer at Clean Planet Technologies.

Dr. Odjo also highlighted the scale of the opportunity, noting that 100,000 commercial flights operate globally every day, while 600,000 tonnes of non-recyclable waste plastics enter the environment. The pilot facility aims to demonstrate that this waste can be turned into a premium product with quantifiable commercial demand.

Supporting UK and Global Sustainability Goals

The Sustainability Innovation Centre plays a critical role in bridging the gap between innovation and commercial development. It has been designed to support fuel and feedstock testing, validation, and progression through the ASTM qualification process. The facility has already secured financial support from the Department for Transport-funded UK SAF Clearing House.

We note that the fundamentals of the process,pyrolysis, purification, distillation, and hydroprocessing,are all technologies currently used independently at a commercial scale, which suggests that scaling up the integrated process will not present a significant challenge for the company.

Meeting the UK’s SAF Mandate

The opening of the pilot facility is an important step toward the UK’s ambition to support sustainable aviation and meet its SAF mandate.

“The Sustainability Innovation Centre is set up to demonstrate our patented waste-plastics-to-SAF process at pilot scale, supporting fuel testing, validation and progression. The important thing is that our pilot facility will support the growth of others, helping the UK to meet its SAF mandate,” added Dr. Katerina Garyfalou, Chief Operating Officer at Clean Planet Technologies.

UK government policy to decarbonize aviation fuel states that 2% of UK jet fuel demand must be SAF, increasing to 10% in 2030 and 22% in 2040.

Addressing Dual Strategic Challenges

Clean Planet Group, founded in 2018, views the new facility as a solution to two pressing global issues. By converting non-recyclable plastics,materials that would otherwise go to landfill or be incinerated,into low-carbon aviation fuel, the facility supports circular economy objectives.

“Our pilot facility addresses two strategic challenges simultaneously: plastic waste management and aviation decarbonisation,” said Clean Planet Group CEO Bertie Stephens.

Stephens noted that the pilot opens up new ways to make sustainable aviation fuel at a time when existing feedstocks, such as energy crops, are becoming harder to secure. It also positions the UK as a leader in turning waste plastics into SAF, supporting UK and European targets, and helping clear the path to commercial-scale plants later this decade.

GAMA Proposes EU Investment Plan to Support Sustainable Aviation

GAMA’s 2026 white paper outlines strategies to address capital shortages and regulatory challenges in Europe’s sustainable aviation sector.

Published

on

This article is based on an official press release from the General Aviation Manufacturers Association (GAMA).

Europe certified the world’s first fully electric aircraft, establishing an early lead in the race toward sustainable aviation. However, a severe capital shortage over the past two years has threatened to hollow out the continent’s pioneering eVTOL sector. In response to this critical juncture, the General Aviation Manufacturers Association (GAMA) has issued an urgent industrial blueprint.

On April 22, 2026, GAMA released a new white paper titled “Wings of Change: A Strategy for Competitiveness, Innovation, Industry, and Investment in Europe’s Sustainable Aviation Sector.” According to the official press release, the document aims to anchor clean aviation manufacturing, encompassing electric, hybrid-electric, and hydrogen-powered flight, firmly within Europe.

We at AirPro News have reviewed the proposals, which are designed to integrate with the European Union’s ongoing Clean Industrial Deal. The white paper outlines actionable measures to mobilize capital, streamline Regulations, and prevent Europe from losing its competitive edge to heavily subsidized markets in the United States and China.

The European eVTOL Capital Crisis

Recent Insolvencies and Market Turmoil

To understand the urgency of GAMA’s 2026 white paper, it is essential to examine the financial turbulence that has recently shaken the European aerospace sector. GAMA’s press release explicitly warns that insufficient access to capital and limited industrial scale-up support have forced several companies into bankruptcy or relocation.

Industry research highlights the high-profile insolvencies of leading German eVTOL developers in late 2024 and early 2025. Lilium filed for insolvency in October 2024 after failing to secure government loan guarantees, ultimately entering a second bankruptcy phase in February 2025 when rescue funding failed to materialize. Similarly, Volocopter filed for insolvency in December 2024, transitioning to regular insolvency proceedings by March 2025. These events underscore the precarious financial reality for capital-intensive aviation Startups operating without robust state backing.

GAMA’s Blueprint for Recovery

Key Proposals from “Wings of Change”

Building upon a previous white paper published in April 2024, GAMA’s latest strategy outlines specific measures for EU policymakers to support the long development cycles inherent in aircraft manufacturing. According to the press release, the white paper proposes a “One-Stop-Shop” investment platform under the proposed EU Competitiveness Fund. This centralized platform would organize research and development, scale-up, and manufacturing funding from both EU institutions and Member States to attract private investors.

Additionally, GAMA advocates for a shift toward performance-based funding tied directly to technological milestones and aviation Certification progress. The organization also stresses the need for regulatory efficiency at the European Union Aviation Safety Agency (EASA), calling for a predictable, flat-fee certification structure for electric and hybrid propulsion systems.

To stimulate early market adoption, the white paper recommends integrating environmental criteria into Public Service Obligation (PSO) tenders and directing revenues from the EU Emissions Trading System (ETS) toward sustainable aviation infrastructure.

“Without stronger Investments frameworks and regulatory backing, Europe risks losing ground in a sector that is making headway in reducing environmental impacts and growing economic opportunity.”

— Péter Márton, GAMA Director of European Government Affairs, via company press release

Global Competitiveness and the Clean Industrial Deal

Aligning with EU Strategy

The GAMA proposals arrive as the European Commission continues to roll out its Clean Industrial Deal, introduced in February 2025. Industry reports note that this deal includes an Industrial Decarbonization Bank with a €100 billion budget and an expansion of the InvestEU program. GAMA is actively lobbying to ensure the sustainable aviation sector receives dedicated focus within this broader €100 billion framework.

The white paper has garnered broad consensus across the European sustainable aviation ecosystem. According to the release, it is backed by major legacy manufacturers, infrastructure developers, and startups, including France’s Safran and Daher, Germany’s Vaeridion and ERC-Systems, the UK’s Vertical Aerospace and ZeroAvia, Switzerland’s H55, and Slovenia’s Pipistrel Aircraft.

AirPro News analysis

We observe that the core of GAMA’s white paper is fundamentally a geopolitical call to action. While European manufacturers initially led the way in certifying electric propulsion, the lack of cohesive government support contrasts sharply with the environment in competing nations. Industry analysts note that U.S. and Chinese eVTOL companies receive significant backing from government and defense agencies, such as the U.S. Department of Defense.

If the European Union does not adopt measures similar to the proposed “One-Stop-Shop” investment platform or performance-based funding, the center of gravity for sustainable aviation manufacturing will likely shift permanently to the U.S. and China. The recent insolvencies of European pioneers serve as a stark warning that technological leadership cannot survive without matching financial and regulatory infrastructure.

Frequently Asked Questions

What is the “Wings of Change” white paper?

Released by GAMA on April 22, 2026, it is an industrial blueprint aimed at securing clean aviation manufacturing in Europe through improved investment frameworks and regulatory efficiency.

Why is the European eVTOL sector struggling?

Despite early technological leads, European eVTOL companies have faced severe capital shortages. High-profile startups like Lilium and Volocopter entered insolvency proceedings in late 2024 and early 2025 due to a lack of government loan guarantees and scale-up support.

How does GAMA propose to fix the funding gap?

GAMA proposes creating a centralized “One-Stop-Shop” investment platform under the EU Competitiveness Fund, shifting to performance-based funding, and utilizing revenues from the EU Emissions Trading System (ETS) to build sustainable infrastructure.
