Bioref. (2013) Abstract: Technoeconomic analysis of renewable aviation fuels has not been widely considered, despite the increasing global attention that the field has received. We present three process models for production of aviation-fuel from microalgae, Pongamia pinnata seeds and sugarcane molasses. The models and assumptions have been deposited on a wiki (http://qsafi.aibn.uq.edu.au) and are open and accessible to the community. Based on currently available long-term reputable technological data, this analysis indicates that the biorefineries processing the microalgae, Pongamia seeds, and sugarcane feedstocks would be competitive with crude oil at $1343, $374, and $301/bbl, respectively. Sensitivity analyses of the major economic drivers suggest technological and market developments that would bring the corresponding figures down to $385, $255, and $168/bbl. The dynamic nature of the freely accessible models will allow the community to track progress toward economic competitiveness of aviation fuels from these renewable feedstocks. © 2013 Society of Chemical Industry and John Wiley & Sons, Ltd Supporting information may be found in the online version of this article.
