An Empirical Analysis on The Use of Sustainable Fuels in The Aviation Industry

Abstract

This study aims to analyze and evaluate different types of alternative fuels for aviation from a life cycle and cost perspective. It aims to analyze different alternative fuels and their use in aircraft for this purpose in the aviation sector in relation to their potential to be a suitable transition solution towards sustainable transformation. Using the GREET (Greenhouse gases, Regulated Emissions, and Energy use in Technologies) aviation module developed by the US National Research Laboratory (Argonne), the life cycles of petroleum and six different sustainable aviation fuel production methods were calculated, and the environmental impact of kerosene and sustainable aviation fuels in terms of cost and carbon dioxide emissions on long, medium and short-haul flights were analyzed. As a result of the study, it was determined that the cost of the sustainable aviation fuels examined was higher than fossil fuel. The key to greater acceptance and deployment of sustainable aviation fuel is cost reduction. In the long term, this will require investment in advanced technologies to process feedstocks more efficiently on a larger scale and in the development of sustainable and scalable feedstock options. However, in the short term, temporary support from governments and other stakeholders through policy incentives is needed. In this sense, this study is of interest to managers of domestic and global airline companies, industry professionals and interested stakeholders.
