Renewable Jet-Fuel (RJF): Mitigation of Aviation-Related GHG Emission

Abstract

An insightful overview of the GHG emission and carbon footprint concerning air transport resulting from the use of conventional Jet Fuel (JF) and possible mitigation by blending with Renewable Jet Fuel (RJF) has been presented. Different production methods of RJF and its performance as green blending stock with JF have been enumerated in terms of mitigation of GHG emission. The prediction of the net GHG emission through life cycle analyses encompassing all stages of RJF production and its end use is also illustrated. Sustainable development of RJF production towards augmentation in blending percentage with JF for GHG emission reduction has been elaborated. RJF is being commercially produced by different public and private sector manufacturers through proprietary technologies utilizing a wide range of non-edible cost-effective feedstocks. The standard RJF as a green blending component for conventional JF needs regulatory ground level and flight trials and approval from aviation authorities. Elaborate information on utilization of RJF in military aircrafts and civilian flights for achieving carbon-neutral growth in several continents has been meticulously presented. The predicted percentage reduction in GHG emission after employment of RJF in different countries has been enumerated. The life cycle analyses of GHG emission encompassing the feedstock cultivation, feedstock conversion to RJF, blending of RJF with petroleum derived JF and the combustion of blended fuel has been elaborately described highlighting the possible carbon footprint mitigation avenues.
