KLM Launches Europe’s First Gas-Free Aircraft Hangar at Schiphol
KLM’s €150M gas-free hangar at Amsterdam Schiphol sets new sustainability standards with 30% energy reduction and 100% fossil-free operations by 2026.
As global aviation faces mounting pressure to reduce emissions, KLM Group’s groundbreaking gas-free hangar project at Amsterdam Schiphol-East signals a transformative shift in aircraft maintenance. This €150 million renovation of Hangar 10 – originally built in 1967 – will become Europe’s first shared maintenance facility operating entirely without fossil fuels by 2026. The initiative comes as airlines worldwide scramble to meet the International Air Transport Association’s (IATA) net-zero carbon emissions target for 2050.
The project’s significance extends beyond its 27,000m² footprint. By co-locating KLM Engineering & Maintenance with Transavia’s Greenbase operations, the Group achieves unprecedented operational synergy while cutting energy use by 30% compared to conventional facilities. With Schiphol Airport handling over 300,000 aircraft movements annually, this facility positions the Netherlands at the forefront of sustainable aviation infrastructure.
The redesigned Hangar 10 incorporates radical sustainability features that set new industry benchmarks. Infrared heating systems replace traditional gas boilers, while 1,200 strategically placed skylights provide 85% of daytime illumination needs. The structure’s BREEAM “Outstanding” certification – the highest sustainability rating – requires meeting strict standards for energy efficiency (≤55 kWh/m²/yr) and circular material use (98% recycled steel).
Operational innovations include electric aircraft tugs with 500kW rapid-charging stations and a closed-loop water system that saves 15 million liters annually. KLM engineers developed specialized containment systems for hydraulic fluids, preventing ground contamination during maintenance. The hangar’s layout reduces aircraft taxi distances by 40%, eliminating 12 tons of CO2 emissions daily from auxiliary power unit usage.
“This facility redefines what’s possible in aviation infrastructure. We’re proving that large-scale industrial operations can decouple from fossil fuels without compromising safety or efficiency.” – Sylca Vellinga, KLM VP of Real Estate
KLM’s green transition extends across its Schiphol operations. Since 2021, Hangar 14’s 8,500 solar panels have generated 4.2 GWh annually – enough to power 1,200 homes. The airline’s ground fleet now uses Neste MY Renewable Diesel, cutting particulate emissions by 33% and CO2 by 90% compared to fossil diesel. Over 140 electric vehicles now service aircraft, with plans to electrify all 350 ground vehicles by 2028.
The new “Link” training center exemplifies this holistic approach. Five full-flight simulators use AI-powered software to reduce pilot training emissions by 70%. Virtual reality systems allow mechanics to practice complex repairs digitally before touching aircraft, minimizing resource waste. These innovations complement KLM’s fleet renewal program, which has added 23 fuel-efficient Airbus A321neos since 2022.
“Our renewable diesel initiative alone prevents 8,500 tons of CO2 annually. When combined with hangar innovations, we’re creating a blueprint for emission-free airport operations.” – Paul Feldbrugge, KLM Zero Emission Program Lead
While KLM’s achievements are impressive, scaling these solutions presents challenges. The hangar’s €3,500/m² construction cost exceeds conventional facilities by 25%, though lifecycle savings are projected to break even within 15 years. Regulatory hurdles remain – current EU regulations don’t fully recognize renewable diesel for aviation ground operations, complicating carbon accounting. Nevertheless, the project has sparked global interest. Singapore Changi Airport recently adopted KLM’s solar panel integration model, while Frankfurt Airport is testing similar electric ground equipment. The International Civil Aviation Organization estimates that widespread adoption of such facilities could reduce global aviation emissions by 8-12% by 2040.
KLM’s gas-free hangar demonstrates that sustainable aviation infrastructure is both feasible and economically viable. By achieving 40% energy savings through design innovation and renewable integration, the project provides a replicable model for airports worldwide. The collaboration between KLM and Transavia proves that airline partnerships can amplify environmental benefits while maintaining operational efficiency.
Looking ahead, the aviation industry must address remaining challenges – standardizing green certifications, developing cleaner aircraft fuels, and creating global incentive structures for sustainable infrastructure. As KLM’s technical teams work to electrify remaining ground support equipment, their progress will likely influence EU aviation policy and international environmental standards in the coming decade.

Honeywell and Verso Energy to Expand eSAF Production Globally
Honeywell and Verso Energy partner to deploy eSAF technology at seven sites in France, Finland, and the US, producing low-carbon aviation fuel.
This article is based on an official press release from Honeywell and additional project documentation.
CHARLOTTE, N.C., In a significant move to scale the production of SAF, Honeywell announced on February 24, 2026, that Verso Energy has selected its UOP eFining™ technology for seven planned production facilities. The agreement covers projects in France, Finland, and the United States, aiming to produce low-carbon electro-sustainable aviation fuel (eSAF) to meet growing regulatory demands.
According to the announcement, Verso Energy, an integrated energy company specializing in low-carbon molecules, will utilize Honeywell’s methanol-to-jet (MTJ) processing solution. Once fully operational, these facilities are projected to produce approximately 200 million gallons of eSAF annually. The partnership leverages Honeywell’s standardized design to reduce capital expenditures and accelerate the timeline for bringing these fuels to market.
The core of this Partnerships is Honeywell’s UOP eFining™ technology, which converts eMethanol, produced from carbon dioxide captured from biological sources and green Hydrogen, into sustainable aviation fuel. This process allows for the creation of “drop-in” fuels that require no modifications to aircraft engines or existing airport infrastructure.
Honeywell reports that eSAF produced through this method can reduce greenhouse gas (GHG) emissions by 88% compared to conventional jet fuel. Barry Glickman, Vice President of Honeywell Low Carbon Energy, emphasized the strategic importance of feedstock flexibility in a company statement:
“Honeywell’s innovative SAF technology portfolio is designed to address two of the biggest challenges in renewable fuel production, cost and feedstock availability. With our eFining technology, companies like Verso Energy can use abundant carbon dioxide as feedstock, making eSAF production scalable and less carbon intensive.”
By utilizing biogenic CO2 rather than lipid-based feedstocks (such as waste oils) used in other SAF production methods, the partnership aims to bypass supply constraints that often limit the scalability of renewable fuels.
The seven planned facilities are strategically located to leverage local industrial infrastructure and renewable energy sources. According to project details released alongside the announcement, the portfolio includes four sites in France, two in Finland, and one in the United States.
In France, Verso Energy is advancing four projects, including the flagship “DEZiR” project in Petit-Couronne (Normandie) and “ReSTart” in Tartas. Both projects have received support from the EU Innovation Fund. The DEZiR facility is expected to be among the first large-scale eSAF plants in Europe, with operations targeted to begin in 2030. In Finland, facilities are planned for the Port of Oulu and Tornio. These sites were selected for their access to biogenic CO2 from the forestry industry and the availability of renewable electricity required for green hydrogen production.
The partnership also marks Verso Energy’s expansion into the U.S. market, with a facility planned for Jesup, Georgia. Similar to the Finnish sites, this location offers access to forestry byproducts and renewable power potential.
The acceleration of these projects is heavily influenced by the European Union’s ReFuelEU Aviation initiative. This regulation mandates that aviation fuel suppliers blend increasing amounts of SAF into their supply, with a specific sub-mandate requiring synthetic fuels (like eSAF) to comprise at least 35% of the fuel mix by 2050.
Antoine Huard, CEO of Verso Energy, highlighted the necessity of cost efficiency in meeting these mandates:
“Efficient and cost-effective eSAF production will be crucial for helping airlines comply with regional adoption requirements. Honeywell’s proven SAF technology paired with our standardized design approach will enable us to quickly scale production capabilities and bring additional eSAF to the market sooner, helping to meet growing global demand.”
The collaboration between Honeywell and Verso Energy highlights a critical pivot in the sustainable aviation sector: the shift from HEFA (Hydroprocessed Esters and Fatty Acids) to Power-to-Liquid (PtL) solutions. While HEFA currently dominates the SAF market, it is constrained by the finite supply of waste oils and fats. eSAF, derived from CO2 and hydrogen, offers theoretically unlimited scalability, provided that renewable electricity is abundant and affordable.
However, the economic viability of eSAF remains a hurdle due to high energy costs. Honeywell’s emphasis on a “standardized design” suggests a strategy focused on modularity to drive down CAPEX, a necessary step if eSAF is to compete with conventional jet fuel without relying entirely on heavy subsidies. The geographic spread of these plants, particularly the entry into Georgia, USA, indicates that Verso is hedging its bets across different regulatory environments, anticipating that the U.S. may eventually adopt synthetic fuel incentives similar to Europe’s ReFuelEU.

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.
