Ethanol Blending for Sustainable Aviation Fuel (SAF)
Why in news?
The Indian government has announced its intention to use ethanol for producing Sustainable Aviation Fuel (SAF), a significant step towards decarbonizing the aviation sector.
Key points
- Ethanol is being explored as a feedstock for Sustainable Aviation Fuel (SAF).
- Aviation is difficult to decarbonize due to current limitations of batteries and hydrogen at commercial scale.
- The process to convert ethanol into jet fuel is known as Alcohol-to-Jet (ATJ), involving dehydration, hydrocarbon chain lengthening, and hydrogenation.
- This initiative aligns with India's goal of becoming self-reliant in energy needs and meeting international emissions frameworks.
Background & context
Sustainable Aviation Fuel (SAF) is crucial for reducing the carbon footprint of the aviation industry. Ethanol, a biofuel, can be produced from various sources and is being investigated as a viable component for SAF production.
★ Prelims fact capsule
The Alcohol-to-Jet (ATJ) process converts ethanol into a usable form for jet engines.
