Are sustainable fuels the solution to decarbonising aviation ? ✈️

? UK start-up Firefly Green Fuels is leading the charge against aviation's greenhouse gas emissions, turning organic waste from sewage into sustainable fuel. In a world where aviation contributes over 3% to global greenhouse gas emissions, this initiative is both relevant and crucial.

? How does it work ?

Firefly Green Fuels employs hydrothermal liquefaction in the lab to convert wastewater into crude oil. In simpler terms, biomass (wastewater in this case) is mixed with water under high pressure and very high temperature. This process extracts organic coal and crude oil, which is then refined into usable fuel.

? What's for ?

According to Firefly Green Fuels, this innovation could reduce the carbon footprint of flights by up to 92% compared to the paraffin currently used. This type of innovation would make it possible to use a raw material from an abundant and cheaper resource.
Encouraged by encouraging laboratory results, the company has partnered with the UK government and the airline Wizz Air to carry out full-scale trials.
However, despite similar performance to current paraffin, it will be at least 2029 before this fuel is used by airlines.?
