Given the enduring issues of human-induced climate change, the appeal of strategies aimed at reducing greenhouse gases has never been greater. CO2 is the most concerning greenhouse gas due to the large quantity already emitted into the atmosphere and the ongoing excessive emissions from anthropogenic activities. The transportation sector significantly impacts global warming, as all major transportation modes depend on fossil fuels. The principal fuel used in aviation is kerosene, which is a jet fuel derived from petroleum. Due to the environmental risks associated with petroleum-based fuels, synthetic kerosene is an appealing alternative that could aid the decarbonisation of the aviation sector. This research study aims to conduct a techno-economic analysis of synthetic kerosene, as a potential sustainable fuel for aviation. To address the excessive CO2 concentrations in the atmosphere, the process of extracting CO2 from the air, known as direct air capture, is investigated. A model is developed in Aspen Plus consisting of four main modules, namely direct air capture with NaOH sorbent and calcium looping, syngas production through the reverse water gas shift reaction, Fischer-Tropsch Synthesis and hydrocracking & distillation. There is a substantial gap in the literature concerning the utilisation of direct air capture technologies for synthetic fuel production, and this study aims to narrow this gap.
