Study Notes

Sustainable Aviation Fuel (SAF)

  • SAF is a type of biofuel, renewable fuel, or non-conventional fuel used to power aircraft.
  • It is a drop-in replacement for standard aviation fuel, allowing it to be blended with up to 50% conventional jet fuel.
  • No changes are needed to existing aircraft or infrastructure to use SAF.
  • SAF can reduce lifecycle CO2 emissions by up to 80% compared to conventional aviation fuel.

Sustainable Aviation Fuel (SAF)

  • SAF is a biofuel/renewable fuel/non-conventional fuel used to power aircraft, serving as a drop-in replacement for standard aviation fuel.

Characteristics

  • Can be blended with up to 50% conventional jet fuel to reduce emissions.
  • Does not require changes to existing aircraft or infrastructure.

Environmental Impact

  • Reduces lifecycle CO2 emissions by up to 80% compared to conventional fuel.

Feedstocks (SAF Sources)

  • Can be produced from various sustainable resources, including:
    • Sugar-bearing plants
    • Forestry and agricultural waste
    • Algae
    • Cooking oil
    • Oil seeds
    • Corn grain
    • Municipal waste

Role in Net Zero Emissions

  • According to the International Air Transport Association (IATA), SAF could contribute around 65% of the reduction in emissions needed by aviation to reach net-zero in 2050.
