Global biorenewable development strategies for sustainable aviation fuel production

Over the coming years, world is projected to witness an upsurge in “drop-in” aviation biofuel production as part of renewable energy and bioeconomy developments. This paper presents a comprehensive review current status biojet fuel development uptake global commercial industry, including state-of-the-art certified technologies (i.e. Fischer-Tropsch (FT); hydroprocessed esters fatty acids (HEFA); alcohol-to-jet (ATJ); hydroprocessing fermented sugars (HFS)); potential feedstock that can be deployed; comparison techno-economic environmental performances routes; airlines’ commitment promoting higher uptake; initiatives policies. shows HEFA route using oil-based crops best performing terms lowest cost greenhouse gas emissions, however it competition with existing road transport market. Lignocellulosic biomass waste should promoted view replacing food/feed which have high indirect land use change emissions. Therefore, further improvement focused on FT, ATJ HFS routes enhance effectiveness promote commercialisation these technologies. The selection for SAF justified based footprint, while avoiding shortcomings policies such blending mandate multiplier RED II addressed reduce negative impacts between sectors meet decarbonisation targets.
