Plant-based jet fuel
GS Paper - 3 (Energy)
Jet fuel derived from a type of mustard plant can replace the petroleum-based aviation fuel to reduce carbon emissions by up to 68 per cent, according to a study led by an Indian-origin scientist in the US. The research estimated the break-even price and life cycle carbon emissions of the sustainable aviation fuel (SAF) derived from oil obtained from Brassica carinata, a non-edible oilseed crop.
- The researchers noted that the aviation industry emits 2.5 per cent of all carbon dioxide emissions from the US and is responsible for 3.5 per cent of global warming.
- Carinata-based SAF could help reduce the carbon footprint of the aviation sector while creating economic opportunities and improving the flow of ecosystem services across the southern region.
- Since carinata is grown in the 'off' season it does not compete with other food crops, and it does not trigger food versus fuel issues.
- Additionally, growing carinata provides all the cover-crop benefits related to water quality, soil health, biodiversity and pollination.
