Papantoni, Linke undertook a comprehensive Life Cycle Assessment focusing on fleet emissions and the overall climate impact. The methodology utilized involved producing hydrogen via water electrolysis followed by Fischer-Tropsch synthesis, aimed at Power-to-Liquid production. The study considered the environmental impacts and potential of PtL, particularly for the aviation sector. One striking result showed that PtL derived from wind energy could reduce environmental impact by up to 42%. Another noteworthy finding was the potential reduction in warming impact due to the phenomenon of contrail-induced cloudiness.
