Atmospheric Carbon-to-Aviation Fuel System AirFuel Completes First Commercial Flight: Extracting CO2 From Air to Make Jet Fuel

On December 2, 2029, Swiss synthetic fuel company Synhelion announced that its atmospheric carbon conversion system AirFuel completed its first commercial flight. A Lufthansa Airbus A320neo powered by AirFuel-produced synthetic aviation kerosene flew from Zurich to Berlin, covering approximately 850 kilometers.

AirFuel's operating principle is a three-step process: first extracting CO2 from the atmosphere through direct air capture technology, then using concentrated solar energy to heat CO2 and water vapor to 1,500°C to produce syngas, and finally converting syngas into aviation kerosene through Fischer-Tropsch synthesis.

Synhelion CEO Philipp Furler said AirFuel-produced synthetic kerosene is chemically identical to conventional aviation kerosene, requiring no modifications to existing aircraft engines. This commercial flight's carbon emissions were zero, as the CO2 released during combustion equals the amount captured from the atmosphere.

However, AirFuel's current cost remains far above conventional aviation kerosene. Each liter of AirFuel kerosene costs approximately $3.5 to produce — four times the price of conventional kerosene. Synhelion expects costs to reach parity with conventional kerosene by 2033 as production capacity expands and solar concentration efficiency improves.

The EU's ReFuelEU regulation, implemented in 2025, requires that sustainable aviation fuel blending reach 6% by 2030. AirFuel's successful commercialization provides airlines with a viable compliance pathway.
