Abstract
The current state of climate change emphasises the need for new practices and technologies, to phase out conventional fossil fuels, which currently contribute significantly to climate change. As most sectors are able to directly electrify, some sectors, including the aviation sector, are currently unable to do so. As the demand for aviation continues to grow, where the sector currently accounts for 2-3 \% of global emissions, it is important to uncover how this sector can reach climate neutrality. in light of this, international and regional plans have been proposed to replace fossil fuel with alternative fuels such as e-SAF. To assess the transition towards e-SAF the fuel demand at CPH Airport in 2050 has been estimated. This has enabled an estimation in domestic feedstock demand to produce e-SAF to cover the fuel demand at CPH Airport. Based on the sources of feedstock supply and expenses of the required technologies for e-SAF production, it is estimated that e-SAF will be more expensive than fossil fuel. However, by driving down the electricity price, the cost gap between e-SAF and fossil fuel is lowered significantly. Additional economic instruments such as \ce{CO2} taxation and system integration of e-SAF production can ensure competitiveness of the e-SAF product. Despite the apparent opportunities of e-SAF, uncertainties and challenges remain regarding renewable power production, which risks jeopardising domestic e-SAF production to cover the fuel demand at CPH Airport.
