What is it?
- Sustainable Aviation Fuel (SAF) is a type of aviation fuel that is produced from renewable sources, unlike traditional fossil-based jet fuels.
Source
- It can be derived from various feedstocks, such as plant oils, agricultural waste, forestry residues, and municipal solid waste.
Advantages
- It has the potential to reduce GHG emissions by up to 80% compared to conventional jet fuel.
- It can be used in existing aircraft engines without modifications and can be blended with conventional jet fuel, making it relatively easy to integrate into existing aviation infrastructure.
Disadvantages
- Four times more expensive than traditional fossil jet fuel.
- Scarcity of waste-based feedstock.
- Lower energy density than traditional jet fuel.
Significance
- It is considered sustainable because it has a significantly lower carbon footprint and reduces greenhouse gas emissions compared to conventional jet fuel.
