In a recent comprehensive study conducted in 2023, Umenweke et al. developed a detailed TEA concentrating on integrated catalytic deoxygenation and hydrothermal gasification methods. The primary aim was to produce H2 gas from esters and fatty acids, with a specific emphasis on tall oil fatty acid (TOFA). Notably, the study revealed that the minimum fuel selling price (MFSP) for Scenario 2 was USD 0.39/L, a figure lower than the USD 0.62/L observed in Scenario 1. A pivotal recommendation stemming from the study was the imperative need for concentrating efforts on process optimization and model improvement . This optimization would be particularly advantageous, especially if guided by the inclusion of both experimental data and kinetics data. The overarching theme of the analysis cantered on the TEA and LCA impacts associated with Sustainable Aviation Fuel (SAF) production, utilizing integrated catalytic deoxygenation and hydrothermal gasification methods. The findings indicate that optimizing these processes could significantly reduce the minimum fuel selling price (MFSP), underscoring the importance of incorporating experimental and kinetics data for further improvements.
