There is growing pressure on the aviation sector to reduce its carbon footprint in order to meet the objectives of the global climate. To reach net-zero emissions, this study investigates the possibilities of synthetic aviation fuels (SAF), particularly Power-to-Liquid (PtL) fuels. The study uses a descriptive research design that combines quantitative and qualitative analysis to evaluate the technical and economic feasibility. A levelized cost model that includes Fischer-Tropsch (FT), electrolysis, direct air capture (DAC), and renewable energy is used in the economic analysis. According to the results, the primary factor influencing the production cost, which is roughly ₹280 per liter, is energy requirements. The robustness of cost projections against changes in capital and operating expenditures is validated by sensitivity analysis. The study looks at synthetic fuels' life cycle effects, compatibility, and performance in addition to economics. Results show notable decreases.in greenhouse gas emissions, high compatibility with existing infrastructure, and scalability potential compared to alternatives such as biofuels, hydrogen, and batteries. Despite challenges related to high costs, energy intensity, and infrastructure requirements, synthetic aviation fuels present a promising “drop-in” solution for near- to mid-term decarbonization. This paper contributes to the growing discourse on sustainable aviation by highlighting the opportunities and barriers associated with SAF adoption, offering guidance to policymakers, researchers, and industry stakeholders.
