Aviation Fuel
Context: In April 2025, China's aviation fuel exports surged to a 13-month high of 1.89 million metric tonnes, driven by increased crude oil imports and rising international travel demand.
Important Pointers:
Definition: Aviation fuel is a specialized type of petroleum-based fuel used to power aircraft. It must meet strict performance and safety standards.
Types of Aviation Fuel:
Jet A / Jet A-1: Kerosene-based fuels used in commercial aviation.
Jet B: More volatile, used in extremely cold regions.
Avgas (Aviation Gasoline): Used in small piston-engine aircraft.
Sustainable Aviation Fuel (SAF): Fuel derived from renewable sources like agricultural waste, algae, municipal waste, etc., that reduces carbon emissions compared to conventional ATF.
Benefits of SAF:
Up to 80% reduction in lifecycle greenhouse gas emissions.
Drop-in fuel: compatible with existing engines and infrastructure.
Reduces soot and sulphur emissions.
Challenges:
Higher production cost.
Limited feedstock availability.
Need for policy support and infrastructure development.
