PtL fuels from renewable energy are the most important climate-friendly alternative to fossil-based kerosene in aviation.

For Germany to achieve climate neutrality by 2045, the aviation sector must do it part. PtL fuels from renewable energy are the most important climate-friendly alternative to fossil-based kerosene in aviation. Now that the right conditions have been created, electricity-based liquid aviation fuels are now finding their way out of the laboratory and onto the market.

Your pioneering spirit and commitment show what can be accomplished.

Solarbelt shows different ways our carbon footprint in the aviation sector can be improved. Your pioneering spirit and commitment show what can be accomplished.

e-kerosene producers are becoming technology pioneers in aviation

It is better to avoid CO2 than to offset it. The new facility is showing energy companies and airlines what can be achieved without government subsidies.

How our fairfuel plant works

Our plant in the town of Werlte in the Emsland region of Germany uses CO2 captured from locally generated wind and solar power, from a biogas plant located directly on the premises and from the air and water to produce synthetic crude kerosene. The refinery in Heide then processes it into Jet A1 kerosene, which is then supplied to the Hamburg airport and used as a carbon-neutral fuel for the air transport system.

The atmosfair fairfuel standard

atmosfair fairfuel is a seal of approval for power-to-liquid (PtL) e-kerosene for aviation. E-kerosene is refined from synthetic crude oil to commercially applicable Jet A1. The crude oil is produced by synthesis processes from the feedstocks CO2 and water using electricity. E-kerosene can be used in existing aviation infrastructure without the need for modification of aircrafts. Thus, e-kerosene has the potential to solve the aviation CO2 problem permanently and sufficiently quickly to meet the Paris climate change goals. In order to exploit this potential, an integral use of PtL technology is required from a climate perspective – this is ensured by the atmosfair fairfuel standard.

Green air travel

CO₂-neutral fuel is just one step on the path to green air travel

Flying contributes to anthropogenic climate change in various ways. In addition to CO₂, global warming is intensified in particular by the formation of ozone, cirrostratus clouds and contrails. e-kerosene reduces these effects and can also serve as a long-term solution to reaching the Paris climate targets for the aviation sector by changing flight routes. But until this can be achieved, it is better for the climate to fly less, even with e-kerosene.
