Jet fuel is a mixture of a variety of hydrocarbons. Because the exact composition of jet fuel varies widely based on petroleum source, it is impossible to define jet fuel as a ratio of specific hydrocarbons. Jet fuel is therefore defined as a performance specification rather than a chemical compound. [1]
Jet fuel is a gas turbine fuel used in propeller and jet fixed-wing aircraft and helicopters. It has a low viscosity at low temperature, has limited ranges of density and calorific value , burns cleanly, and remains chemically stable when heated to high temperature.
As of 2023, fuel represents 20–30% of the airlines' operating costs, while SAF is 2–4 times more expensive than fossil jet fuel. [75] Projected cost decreases of green hydrogen and carbon capture could make synthetic fuels more affordable, and lower feedstock costs and higher conversion efficiencies would help FT and HEFA biofuels.

SAF burns like normal jet fuel and produces the same amount of emissions while a plane is flying, but it has a lower carbon footprint during its entire production cycle, because it’s usually ...
The U.S. has set aspirational goals to produce 3 billion gallons of SAF per year by 2030, with 100% of commercial jet fuel being SAF by 2050. The U.K. hopes 10% of jet fuel will come from ...
Virgin’s Flight 100 was the world's first transatlantic flight using 100% sustainable aviation fuel on a commercial jet and garnered the airline and its partners a prize of 1 million pounds from ...
Kerosene-type fuels include Jet A, Jet A-1, JP-5 and JP-8. Naphtha-type jet fuels, sometimes referred to as "wide-cut" jet fuel, include Jet B and JP-4. "Drop-in" biofuels are biofuels that are interchangeable with conventional fuels. Deriving "drop-in" jet fuel from bio-based sources is ASTM approved via two routes. ASTM has found it safe to ...
Through Air Company's partnerships with the Department of Defense, its product has already powered experimental jet flights and does not have to be mixed with traditional aviation fuel to be used ...
