Coconut Oil Just Fueled a Jet Engine Test, and the Results Are Wild

Chemists at Osaka Metropolitan University pulled off something that sounds like a stunt but isn’t: they made aviation fuel from coconut oil and ran it in a jet engine. The feedstock is waste coconut left over from commercial oil extraction, and the process works at room temperature and low heat, a much gentler route than typical biofuel production.

In the engine test, the coconut blend performed comparably to pure kerosene on thermal efficiency. Unburned hydrocarbon emissions fell between 5 and 40% depending on the blend, while CO2 and nitric oxide stayed consistent across blends from 10% to 50% biofuel. Aviation remains one of the hardest sectors to decarbonize, so a low-temperature fuel from food waste is a real development.

The catch: carbon monoxide emissions increased, which researchers say must be addressed before this goes commercial, especially for ground crews working around aircraft. Still, the proof of concept is real, and the coconut oil in your smoothie just got a serious side hustle. Would you board a coconut-fueled flight? Tell us in the comments.
