During a test they already ran one engine on sustainable peut
If you look carefully, you will spend just as much for a return flight to Bulgaria as for a train ticket from Lunteren to Groningen. And that is without exaggeration. How can that be so cheap? One of the reasons is that no excise duties are levied on kerosene, at least not in the Netherlands. Now there are plans to introduce that at some point, but maybe it’s just better to make the stuff more sustainable.
That is why Rolls-Royce is working with Boeing on engines that run on Sustainable Aviation Fuel (SAF). This week, the companies ran a nearly four-hour flight to test the stuff. One of the four engines ran on the sustainable fuel during the flight. The other three engines ran on standard kerosene. By 2023, all Rolls-Royce aircraft engines must be able to run at 100 percent SAF. A similar fuel for cars will hopefully follow soon.
Sustainable Aviation Fuel (SAF) is already partly used in aviation, but it is always mixed in. Flights that fly 100 percent on SAF are not yet available. The pod is made from, for example, waste oil, such as used cooking oil from the kitchen. Bottom line, it would provide 80 percent less emissions compared to traditional kerosene. There will be no fully electric scheduled flights for the time being.
