• SWISS is set to become the world’s first airline to use Solar Aviation fuel (“sun-to-liquid” fuel).
• Synhelion is set to build the world’s first facility to industrially produce solar fuel in Julich, Germany. The plant will become operational from 2022 onwards.
• SWISS will become the first customer of solar kerosene in 2023.

• Solar Aviation fuel: SWISS and the Lufthansa Group have concluded a strategic collaboration with Synhelion, Swiss Federal Institute of Technology (ETH Zurich) spinoff, to bring solar aviation fuel to market.
• Synhelion has developed a key technology for manufacturing sustainable aviation fuel (SAF) from renewable energy sources
• The process uses concentrated solar heat to manufacture syngas which can then be synthesized into carbon-neutral kerosene using standard industrial processes.
• This sun to liquid fuel will only produce as much as carbon dioxide as used in to its manufacture.
• This fuel will contribute to effectively decarbonizing air transport.
