The Path to Decarbonizing Aviation
Aviation plays a crucial role in global transportation, contributing two to three percent of worldwide carbon dioxide emissions. As the industry moves toward ambitious climate targets, one of the most viable solutions emerging today is sustainable aviation fuel (SAF). Unlike traditional jet fuel, SAF is derived from renewable sources and can significantly reduce greenhouse gas emissions. While electrification and hydrogen-powered flight are promising, they remain impractical for long-haul journeys, making SAF the leading alternative for decarbonizing the aviation sector.
Innovating the Future: The Take-Off Project
To accelerate the transition to cleaner fuels, TNO is leading the Take-Off project, a European initiative focused on advancing synthetic kerosene production. This four-year collaboration unites scientific institutions, energy companies, and aviation stakeholders to develop a more efficient and cost-effective method of SAF production. The innovation at the heart of this effort is the conversion of CO2, water, and green energy into synthetic kerosene, offering a sustainable alternative to fossil-based jet fuel.
Revolutionary SIENNA Technology
A game-changing element of this project is TNO’s patented SIENNA reactor technology. Unlike conventional processes that generate syngas (a mixture of carbon monoxide and hydrogen) before converting them into hydrocarbons, SIENNA simplifies the process into just two efficient steps. This breakthrough allows CO2 to be directly converted into light olefins (ethylene and propylene) and then into kerosene with high precision and minimal waste. The result is a cleaner, energy-efficient approach to fuel production, eliminating complex refining processes and reducing emissions.
Building a Global Alliance for Sustainable Aviation
The success of SAF depends on strong partnerships across the aviation ecosystem. The Take-Off project exemplifies this by bringing together leading organizations from science and industry. Universities from France (CNRS), Denmark (SDU), and Germany (RWTH Aachen) contribute scientific expertise, while major energy and aviation companies—including Mitsubishi Hitachi Power Systems, RWE, AsahiKasei Europe, and SkyNRG—are driving commercialization. KLM, Total, ExxonMobil, and CO2 Value Europe also provide strategic guidance, ensuring that SAF development aligns with industry needs.
Reducing Costs and Scaling SAF Production
One of the primary challenges in SAF adoption has been cost competitiveness with traditional jet fuel. However, initial research from the Take-Off project suggests that this new production method requires significantly less energy, potentially reducing SAF costs by 30 to 40 percent. By making sustainable fuel more affordable and scalable, the project paves the way for increased adoption across the aviation sector.
Regulatory Momentum and Industry Commitments
With governments worldwide enacting policies to decarbonize aviation, initiatives like the EU’s ReFuelEU Aviation Regulation are creating a market for SAF by mandating minimum blending requirements. Additionally, voluntary commitments under the Science Based Targets Initiative (SBTi) and Carbon Offsetting and Reduction Scheme for International Aviation (CORSIA) are pushing airlines toward cleaner energy solutions. As the aviation industry prepares for net-zero emissions by 2050, the Take-Off project represents a critical step toward achieving this vision.
Conclusion: Transforming Aviation for a Greener Future
Sustainable aviation fuel is no longer a distant goal—it is an essential solution for reducing aviation’s environmental impact. By leveraging CO2, water, and renewable energy, the Take-Off project is helping shape a cost-effective, scalable, and climate-friendly alternative to conventional jet fuel.
