A techno-economic analysis of viable scenarios for the aviation industry to achieve net-zero CO2 emissions is presented. These are based (i) on carbon capture and storage (CCS), where conventional fossil jet fuel produced, corresponding offset by capturing CO2, either via direct air (DAC-CCS route) or point-source (PSC-CCS route), permanently storing it underground, (ii) utilization (CCU), synthetic produced using as feedstock, which captured from (DAC-CCU a emitter (PSC-CCU route). All routes feasible have their advantages shortcomings. To ensure emissions, feedstock emitter, both CCS- CCU-based routes, must be biogenic nature. quantitative assessment these business-as-usual (BAU) scenario, subjected tax, performed cost price projections until 2050. Cost reductions due wide deployment economy scale current low-maturity technologies accounted for. Parametric Monte Carlo sensitivity analyses assess effects uncertainty associated with most relevant quantities observed trends. Findings show that CCS-based consistently lead lower costs than across considered time analyses. This mainly fact result in an energy consumption more 20 times higher also implies when considering intensity electricity grids. Overall, PSC-CCS route represents cost-effective solution decarbonizing industry, cost-competitive BAU already today.
