Pigs might fry: a sustainable aviation tale

Qantas has successfully flown its first flight using fuel distilled from recycled cooking oil, but a look at the data suggests the aviation sector has plenty to do to convert to more sustainable fuels.

Less than six years after an Australian senior energy bureaucrat announced in a Parliamentary hearing that new technologies can overcome peak oil (“if the price of eggs is high enough, even the roosters will start to lay”) this “chooks-to-liquids” fuel (CTL1) has been further developed into a generation two fuel called “cooking-to-liquids” (CTL2).
