Three selected long-term feedstocks and production pathways for renewable "drop-in" jet fuel are compared in a holistic and transparent assessment. The results show the individual strengths and weaknesses of hydroprocessed oil from microalgae and two Fischer-Tropsch synthetic paraffinic kerosenes, one based on woody biomass (Biomass-to-Liquid, BtL) and the other based on "inverse combustion" in a novel two-step solar-driven thermochemical process (Sunlight-to-Liquid, StL). According to the assessment, that gives a high priority to the criteria production costs, greenhouse gas emissions and fresh water consumption, the thermochemical "inverse combustion" technology represents the most promising option, closely followed by fuel production from woody biomass. Hydrotreated microalgal oil was ranked lowest, mainly because of the enormous production costs of the fuel production pathway.
