E-Kerosene
A cleaner future is taking off — quite literally.
A new type of fuel, known as e-kerosene, is poised to reshape the aviation industry. Unlike conventional jet fuel, which is derived from crude oil, e-kerosene is produced synthetically using carbon dioxide (CO₂) captured from the atmosphere, hydrogen extracted from water, and renewable electricity — typically from wind or solar sources. This sustainable aviation fuel (SAF) has the potential to reduce up to 90% of lifecycle carbon emissions compared to fossil-based kerosene.
And it’s not just theory anymore. In 2024, the world’s first industrial plant dedicated to producing e-kerosene officially opened in Germany. Backed by the EU and a consortium of climate-tech companies, this milestone marked the beginning of what many hope will be a new era for long-distance travel: carbon-neutral aviation.
How it works
E-kerosene is created through a process called Fischer-Tropsch synthesis, which combines green hydrogen (H₂) with CO₂ to produce liquid hydrocarbons — synthetic fuels that can directly replace fossil-based kerosene. The hydrogen is extracted via electrolysis powered by renewable energy, often wind or solar. Because the process reuses CO₂ from the atmosphere, the resulting emissions are effectively circular, significantly lowering the overall carbon footprint of aviation.
Unlike other experimental fuels, e-kerosene is a drop-in replacement, meaning it can be used in existing aircraft engines and airport fueling infrastructure without modification. This makes the transition to greener aviation more feasible in the short term.
The road to scale
Despite its promise, e-kerosene is still expensive to produce. One of the main barriers is the availability of cheap, renewable electricity — a critical ingredient in green hydrogen production. In addition, scaling up CO₂ capture technologies and developing efficient supply chains for synthetic fuels are challenges that researchers and policymakers are actively working to overcome.
To address this, the European Union has introduced the ReFuelEU Aviation initiative, which mandates that all jet fuel supplied at EU airports include at least 2% sustainable aviation fuel by 2025, and 70% by 2050. Other countries, including the United States, are also introducing incentives and subsidies to accelerate SAF development.
A global solution for a global problem
Aviation accounts for about 2.5% of global CO₂ emissions, but because these emissions occur high in the atmosphere, their warming impact is significantly amplified. With international travel expected to rebound and grow in the coming decades, finding sustainable alternatives to jet fuel is no longer optional — it’s essential.
E-kerosene presents a scalable, high-energy-density solution that could decarbonize long-haul flights, cargo transport, and even military aviation, sectors where battery-powered alternatives remain impractical.
For now, e-kerosene is still in its infancy, but if investments continue and technological breakthroughs follow, the dream of climate-neutral flying may be closer than we think.
Frequently Asked Questions
What is e‑kerosene made from?
E‑kerosene is produced from atmospheric CO₂, hydrogen extracted from seawater, and renewable electricity via Fischer‑Tropsch synthesis.
Can existing aircraft use this fuel?
Yes. E‑kerosene is chemically identical to conventional jet fuel and meets all ICAO safety and performance standards.
How much does it reduce emissions?
Compared to fossil-based aviation fuel, e‑kerosene can reduce lifecycle CO₂ emissions by up to 90%.
Is e‑kerosene already in use?
Yes, initial test flights have already used e‑kerosene blends. Widespread adoption is expected as production scales up.
