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.
