ICEFlight Program Advances Hydrogen-Powered Aviation Tech
Airbus and GKN Aerospace collaborate on cryogenic hydrogen systems and superconducting motors to enable zero-emission flights, backed by Dutch funding and EU climate targets.
As the aviation industry seeks sustainable alternatives to fossil fuels, hydrogen has emerged as a frontrunner in the race toward zero-emission flight. The ICEFlight (Innovative Cryogenic Electric Flight) program, spearheaded by Airbus and supported by GKN Aerospace, represents a major leap forward in addressing the technical and infrastructural challenges of hydrogen-powered aviation. By leveraging cryogenic technologies and superconducting systems, ICEFlight aims to unlock the potential of liquid hydrogen (LH2) for commercial aircraft.
This initiative comes at a critical time. With the European Union’s Green Deal targeting a 55% reduction in transport emissions by 2030 and net-zero by 2050, hydrogen aviation is not just a technological ambition, it’s a policy imperative. ICEFlight is designed to mature the core systems needed for hydrogen-electric propulsion, including cryogenic storage, superconductive power distribution, and integrated propulsion testing. The program’s success could redefine the aerospace landscape and set a new standard for climate-conscious innovation.
Hydrogen’s low volumetric energy density at ambient conditions requires it to be stored as a cryogenic liquid at -253°C. This presents significant engineering challenges, particularly in maintaining safety, minimizing boil-off, and ensuring structural integrity during repeated flight cycles. Airbus’s Zero Emission Development Centres (ZEDCs) have been at the forefront of developing composite and metallic LH2 tanks capable of enduring over 20,000 flight cycles.
The ICEFlight program builds upon these developments by integrating LH2 not only as a fuel but also as a coolant. This dual-use approach enhances system efficiency and supports the thermal regulation of superconducting motors and power cables. GKN Aerospace, a key partner in ICEFlight, focuses on the design and validation of these cryogenic systems, drawing on its experience from previous hydrogen initiatives like H2Gear.
Thermal management is critical to the success of superconducting systems, which require extremely low temperatures to maintain minimal electrical resistance. By using LH2 as a cooling medium, ICEFlight aims to reduce the weight and complexity of onboard electrical systems while increasing their power density.
“By leveraging our expertise in hydrogen and electrification, ICEFlight marks a step toward scalable solutions for larger aircraft.” , Russ Dunn, CTO, GKN Aerospace
Traditional fuel cells have struggled to meet the power and weight requirements of commercial aviation. However, recent advancements have shifted this narrative. In 2023, Airbus’s joint venture with ElringKlinger, Aerostack, demonstrated a 1.2 MW fuel cell system, proving that large-scale hydrogen-electric propulsion is technically feasible.
ICEFlight takes this a step further by exploring superconductivity, materials that exhibit near-zero electrical resistance at cryogenic temperatures. These materials significantly reduce energy losses in power transmission and enable the development of lightweight, high-efficiency electric motors. This could revolutionize aircraft design, allowing for distributed propulsion systems and more aerodynamic configurations.
The integration of superconductive power networks is expected to reduce electrical losses by up to 90% compared to conventional systems. This not only improves overall energy efficiency but also supports the goal of achieving longer flight ranges and higher payload capacities for hydrogen-powered aircraft. ICEFlight is part of the Dutch government’s “Luchtvaart in Transitie” (LiT) initiative, which has allocated €383 million from the National Growth Fund to support sustainable aviation technologies. The program is coordinated by Airbus UpNext, the innovation arm of Airbus, in collaboration with GKN Aerospace, Royal NLR, and academic partners such as Delft University of Technology and the University of Twente.
This consortium structure enables a multidisciplinary approach to problem-solving, combining industrial expertise with cutting-edge academic research. Royal NLR provides testing facilities to simulate real-world flight conditions, ensuring that the technologies developed are viable for commercial use.
GKN Aerospace’s pivot toward cryogenics, following its exit from the HyFIVE and H2Gear projects, reflects a strategic realignment toward areas with greater commercial potential. The company now focuses on thermal management systems that are critical to the performance of LH2-powered aircraft.
The ICEFlight program has set ambitious targets. By 2027, the consortium aims to validate a 2 MW hydrogen-electric powertrain, incorporating multiple fuel cell stacks, cryogenic cooling systems, and superconductive motors. This prototype will serve as a testbed for future commercial aircraft under the Airbus ZEROe program, now targeting entry into service by 2040.
Key focus areas include the development of composite LH2 tanks with up to 50% weight savings, superconducting motors with high power density, and integrated propulsion systems that combine fuel cell output with electric thrust generation. These components are being designed for scalability to accommodate various aircraft sizes and mission profiles.
In parallel, the program supports the creation of simulation tools and certification pathways, addressing one of the major bottlenecks in hydrogen aviation: regulatory readiness. These efforts will help bridge the gap between laboratory demonstrations and commercial deployment.
“ICEFlight is catalyzing breakthroughs that will define the future of flight.” , Rob Postma, CEO, Airbus Netherlands
The Netherlands is positioning itself as a global leader in cryogenic aviation technologies. ICEFlight’s test infrastructure at Royal NLR not only supports the program’s immediate goals but also serves as a national asset for future aerospace R&D. This ecosystem is expected to generate spin-off applications in sectors such as energy storage, high-speed rail, and maritime transport.
According to Marloes van Put, Head of Airbus Tech Hub Netherlands, this collaboration “strengthens the Dutch ecosystem’s global competitiveness.” The integration of academic and industrial partners ensures a steady pipeline of talent and innovation, reinforcing the country’s role in the global hydrogen economy. Beyond national borders, ICEFlight contributes to the European Union’s broader climate goals. It aligns with the EU’s Clean Aviation Joint Undertaking and complements other initiatives like Clean Hydrogen for Europe, creating synergies across sectors and member states.
Hydrogen is increasingly viewed as essential to achieving net-zero emissions in aviation. McKinsey estimates that hydrogen could supply up to 30% of aviation’s energy demand by 2050, particularly for short- and medium-haul routes under 2,500 kilometers. The Air Transport Action Group (ATAG) echoes this outlook, emphasizing the need for technological breakthroughs to unlock hydrogen’s full potential.
ICEFlight’s innovations, especially in cryogenic storage and superconducting systems, could extend hydrogen’s applicability to larger aircraft and longer routes. This would significantly broaden the market for hydrogen aviation and accelerate its adoption across airline fleets.
However, widespread deployment depends on the development of global hydrogen infrastructure. According to industry estimates, approximately €500 billion will be needed by 2050 to build LH2 production, storage, and refueling capabilities at airports worldwide.
The ICEFlight program illustrates the kind of collaborative, cross-sector innovation required to decarbonize aviation. By focusing on cryogenic technologies and superconducting systems, the initiative addresses some of the most critical barriers to hydrogen-powered flight. The program’s success could pave the way for Airbus’s ZEROe aircraft, featuring multi-megawatt fuel cells, lightweight LH2 tanks, and superconductive propulsion systems.
Looking ahead, ICEFlight’s outcomes will influence not only aircraft design but also energy policy, airport infrastructure, and international regulations. Continued investment and policy support will be essential to scale these technologies and bring hydrogen aviation from prototype to runway. As the world grapples with the climate crisis, ICEFlight offers a tangible solution with transformative potential.

SkyNRG Closes Financing for Europe’s First Standalone SAF Plant
SkyNRG reaches financial close for DSL-01, Europe’s first standalone SAF plant in the Netherlands, targeting full operations by mid-2028.
This article is based on an official press release from SkyNRG and accompanying project documentation.
SkyNRG has officially reached financial close for DSL-01, its first dedicated commercial-scale Sustainable Aviation Fuel (SAF) production facility. Located in Delfzijl, Netherlands, the project marks a significant milestone in the European aviation sector’s transition to renewable energy. According to the company’s announcement, construction on the facility has already commenced, with full operations targeted for mid-2028.
The DSL-01 project is distinguished as Europe’s first standalone greenfield SAF plant, meaning it is being built from the ground up rather than as an expansion of an existing fossil fuel refinery. Once operational, the facility is projected to produce 100,000 tonnes of SAF annually, alongside 35,000 tonnes of by-products including bio-propane and naphtha.
Maarten van Dijk, CEO and Co-Founder of SkyNRG, emphasized the strategic importance of this development in a statement regarding the launch:
“Reaching this important milestone… marks an important step in our transition to becoming an owner and operator of SAF production capacity. This milestone demonstrates growing market confidence in scalable SAF production and provides a model for future sustainable fuel projects globally.” The facility will utilize Topsoe’s HydroFlex™ technology, operating on the Hydroprocessed Esters and Fatty Acids (HEFA) pathway. SkyNRG has stated that the plant will process waste oils and fats,predominantly sourced from regional industries,and will explicitly exclude virgin vegetable oils such as palm or soy to avoid competition with food supplies. The project aims to deliver a lifecycle CO2 emissions reduction of more than 85% compared to fossil jet fuel.
Technip Energies has been awarded the Engineering, Procurement, and Construction (EPC) contract for the site. While specific contract values are often confidential, industry reports estimate the value between €500 million and €1 billion. The construction phase is expected to generate hundreds of jobs in the Groningen Seaports region, contributing to the area’s developing green industrial cluster.
A critical aspect of the DSL-01 project is its financial structure. It is the first commercial-scale SAF plant to secure non-recourse project financing, a move that signals increasing maturity in the SAF market. Under this structure, lenders are repaid based on the project’s future cash flow rather than the general assets of the parent company.
The investment consortium includes: Arjan Reinders, Head of Infrastructure Europe at APG, noted the alignment of this investment with broader sustainability goals:
“SkyNRG represents the first investment in the SAF sector on behalf of our client [ABP], which is closely aligned with our ambition to create impact by investing at the forefront in energy transition assets.” To ensure the commercial viability of the plant, SkyNRG has secured long-term offtake agreements. KLM Royal Dutch Airlines has committed to purchasing 75,000 tonnes of SAF annually for a period of 10 years. This volume represents three-quarters of the plant’s total SAF output and is essential for KLM to meet upcoming EU mandates under the ReFuelEU Aviation Regulation.
Additionally, SHV Energy has agreed to purchase the bioLPG (bio-propane) by-products produced by the facility. Shell, a strategic partner of SkyNRG since 2019, retains an option to purchase SAF from the plant and continues to provide technical and commercial expertise.
The successful financial close of DSL-01 represents a pivotal moment for the SAF industry, specifically regarding “bankability.” Historically, SAF projects have struggled to attract traditional project finance due to perceived technology and market risks. The willingness of a major banking syndicate to provide non-recourse debt suggests that financial institutions now view HEFA-based SAF production as a stable asset class.
Furthermore, the timing of this project aligns directly with the European Union’s “Fit for 55” regulatory package. With the ReFuelEU Aviation Regulation mandating a 2% SAF blend by 2025 and rising to 6% by 2030, the DSL-01 facility will come online just as demand pressures intensify. Unlike competitors expanding existing refineries, SkyNRG’s success with a standalone greenfield site provides a “proof of concept” that could accelerate the development of similar independent facilities globally, such as their planned projects in the United States and Sweden.

Asia-Pacific Aviation Growth and Sustainable Aviation Fuel Initiatives 2026
Asia-Pacific aviation growth faces decarbonization challenges with new SAF mandates and Airbus’s just transition strategy at Singapore Airshow 2026.
This article is based on an official press release from Airbus and additional industry reporting regarding the Singapore Airshow 2026.
As the aviation industry gathers for the Singapore Airshow 2026, the Asia-Pacific (APAC) region stands as the focal point of global aerospace growth. According to recent industry forecasts, APAC is projected to account for over 50% of global aviation growth between 2025 and 2026. However, this rapid expansion presents a critical challenge: reconciling a forecast 7.3% increase in passenger traffic with urgent decarbonization goals.
In a press release issued on February 2, 2026, Airbus outlined a strategy focused on a “just transition.” The European manufacturer argues that the adoption of Sustainable Aviation Fuel (SAF) in Asia-Pacific offers more than just environmental compliance; it presents a pathway for regional socioeconomic development and energy sovereignty.
While the primary driver for SAF adoption globally has been carbon reduction, Airbus emphasizes that for the APAC region, the benefits are deeply tied to local economic resilience. The region possesses abundant feedstock potential, including agricultural residues, used cooking oil, and palm oil waste.
According to the Airbus announcement, utilizing agricultural waste for fuel production addresses multiple local issues simultaneously. In many parts of Asia, the burning of agricultural fields contributes significantly to seasonal air pollution. By converting this biomass into SAF, the region can reduce local smog while creating new revenue streams for rural communities.
Airbus describes this approach as a “just transition,” ensuring that the shift to green energy supports developing economies rather than hindering them. The manufacturer notes that developing local production capabilities also boosts “regional energy sovereignty,” reducing the reliance on imported fossil fuels.
“Given the broad socioeconomic diversity… Asia-Pacific is a prime place to demonstrate the possibilities for a just transition. Leveraging co-benefits could open opportunities to build community resilience.”
, Airbus Press Release, February 2, 2026
Beyond manufacturer initiatives, government policy in the region is hardening. Data released in conjunction with the Singapore Airshow highlights a wave of new mandates and targets aimed at accelerating SAF uptake. Most notably, Singapore has confirmed the introduction of a SAF levy for all flights departing from Changi Airport starting October 1, 2026. This levy is designed to fund a national 1% SAF target by the end of the year, with plans to scale to 3-5% by 2030.
Other regional developments include:
The push for decarbonization is also visible on the tarmac. During the Singapore Airshow, an Airbus A350-1000 is performing flying displays powered by a 35% SAF blend. The fuel, supplied by Shell Aviation, was produced via the HEFA-SPK pathway using used cooking oil and tallow.
In a significant move for propulsion technology, Airbus, CFM International, and the Civil Aviation Authority of Singapore (CAAS) signed a Memorandum of Understanding (MOU) on February 2. This agreement establishes Singapore as the world’s first airport testbed for the “RISE” (Revolutionary Innovation for Sustainable Engines) program. The initiative aims to test “Open Fan” engine architecture, which targets a 20% improvement in fuel efficiency.
Additionally, Airbus and Cathay Group have reiterated their commitment to a US$70 million joint investment, originally announced in late 2025, to accelerate SAF production projects with commercial viability in the region.
While the regulatory and technological momentum is palpable, a stark reality remains. Industry data indicates that global SAF output reached only 1.9 million tonnes in 2025, representing a mere 0.6% of total jet fuel demand. With APAC passenger traffic expected to grow by 7.3% in 2026, the gap between demand for travel and the supply of green fuel is widening.
The “green premium”, where SAF costs 2x to 4x more than conventional jet fuel, remains the primary hurdle. While the “just transition” narrative provided by Airbus offers a compelling long-term vision for feedstock utilization, the immediate success of these initiatives will depend heavily on whether the new levies and investments can bridge the price gap quickly enough to meet the 2027-2030 mandates.

FedEx Expands Sustainable Aviation Fuel Program to DFW and JFK Airports
FedEx expands sustainable aviation fuel use to Dallas-Fort Worth and JFK airports, supporting its carbon-neutral goals with 5 million gallons secured for 2025.
This article is based on an official press release from FedEx.
FedEx has officially expanded its SAF program to include Dallas-Fort Worth International Airport (DFW) and John F. Kennedy International Airport (JFK). The logistics giant announced the move on January 29, 2026, marking a significant step in its “Priority Earth” sustainability roadmap. With these additions, FedEx now utilizes SAF at five airports across the United States.
According to the company’s announcement, the expansion is supported by World Fuel Services (WFS), which manages the supply chain and delivery of the fuel. The initiative positions FedEx as the first airline, cargo or passenger, to purchase SAF for regular commercial operations at DFW, a major global logistics hub.
The agreement covers the purchase of approximately 2 million gallons of “neat” (unblended) SAF for these two locations. When combined with agreements for other hubs, FedEx has secured a total of 5 million gallons of neat SAF for delivery throughout 2025.
While the purchasing agreements are calculated in gallons of “neat” SAF, the fuel actually delivered to aircraft is a blend. Safety regulations currently prohibit the use of 100% SAF in commercial aircraft engines. Consequently, the fuel supplied to FedEx at DFW and JFK is a mixture containing a minimum of 30% neat SAF blended with conventional Jet A fuel.
World Fuel Services facilitates this supply, typically sourcing the renewable component from Valero’s Diamond Green Diesel (DGD) joint venture. The SAF is produced via the HEFA (Hydroprocessed Esters and Fatty Acids) pathway, utilizing waste-based feedstocks such as used cooking oil, animal tallow, and distiller’s corn oil. This production method allows for a lifecycle greenhouse gas (GHG) emissions reduction of up to 80% compared to standard petroleum-based jet fuel.
In a statement regarding the logistical achievement, Bradley Hurwitz, Senior Vice President of Supply & Trading at World Fuel Services, noted:
“FedEx’s purchase at DFW and JFK demonstrates how our aviation fuel distribution platform enables carriers to access lower-carbon fuel options with a robust supply chain designed for flexibility and scale.”
This expansion is part of FedEx’s broader strategy to achieve carbon-neutral global operations by 2040. The company has set an interim target to source 30% of its total jet fuel from alternative fuels by 2030. The addition of DFW and JFK complements existing SAF programs at Los Angeles International Airport (LAX), Chicago O’Hare (ORD), and Miami International Airport (MIA). Karen Blanks Ellis, Chief Sustainability Officer at FedEx, emphasized the progress made over the last year:
“Expanding SAF use by FedEx to include our operations at DFW and JFK caps off a successful year of SAF deployments coast-to-coast. While we know there remains work ahead to procure more SAF… we are proud of our steps forward.”
The introduction of SAF at Dallas-Fort Worth is particularly notable. While pilot programs have existed at DFW since 2021, they were largely limited to business aviation. FedEx’s commitment marks the first regular commercial adoption at the airport, signaling a shift from experimental to operational use in the cargo sector.
However, the industry faces significant headwinds. SAF currently trades at a premium of two to five times the price of conventional jet fuel. Furthermore, global production remains less than 1% of total jet fuel demand. While the “book and claim” system and government incentives like the U.S. Inflation Reduction Act help bridge the cost gap, the physical availability of SAF remains the primary bottleneck for large-scale adoption.
By securing 5 million gallons of neat SAF for 2025, FedEx is signaling consistent demand to producers, which is essential for stimulating the investment required to increase production capacity.
Airport officials have welcomed the move as a validation of existing infrastructure capabilities. Because the blended fuel is a “drop-in” solution, it requires no modifications to airport storage tanks or hydration systems.
Robert Horton, Vice President of Environmental Affairs at DFW Airport, stated:
“FedEx’s SAF purchase reflects how airlines, airports, and fuel providers work together within existing airport infrastructure to support the development of more sustainable aviation operations.”
“Neat” SAF refers to the pure, unblended sustainable fuel. It is not used in aircraft in this form due to safety regulations. Instead, it is blended with conventional jet fuel before delivery. Purchasing agreements often cite “neat” volumes to track the exact amount of renewable content purchased.
As of early 2026, FedEx utilizes SAF at five U.S. airports: Dallas-Fort Worth (DFW), John F. Kennedy (JFK), Los Angeles (LAX), Chicago O’Hare (ORD), and Miami (MIA). The specific SAF used in this agreement, produced via the HEFA pathway, can reduce lifecycle greenhouse gas emissions by up to 80% compared to conventional jet fuel.
