The purpose of this paper is to provide an exhaustive review of the elements hindering SAF deployment and the implications behind the massive use of SAF to replace fossil jet fuel, in order to determine policy options. [...] The paper has four objectives: (1) to review the various factors affecting the availability of SAF inputs (resources, energy, technology), to identify, when possible, the main challenge for each pathway, (2) to evaluate the cost implications of these factors, (3) to analyze the recent dynamics in SAF development and discuss the credibility of SAF 2 development prospects, and (4) to examine impleme. [...] Notwithstanding the validity of these projections, the reviewed literature consistently stresses the extent of the collect and processing infrastructure that must be developed to support the large-scale deployment of bio-jet fuel. [...] Lignocellulose and microalgae correspond respectively to the maximum values of ATJ and HEFA, the latter multiplying by 10 the cost of the fuel compared to other oils [30] as a result of the lack of large-scale commercial applications of microalgae production [40]. [...] The other option is to impose blending mandates or, in other words, imperative SAF incorporation rates in the airports inside a given territory: they send a strong demand signal, incentivize the energy providers to invest in lowering the costs of SAF, and give a higher impetus to reach the targets, being one of the most effective policies to achieve technological change [31,122].
