(302b) Supply Chains Analysis for Sustainable Production of Aviation and Marine Biofuels: A Comparative Study of Feedstocks, Technologies, Regions, and GHG Emissions
One of best results for aviation biofuel production are obtained when Brazilian sugarcane bagasse is directly upgraded to jet via FP with a minimum selling price (MSP) of around 2200 US$/ton biojet. The MSP could further be reduced if lignin is considered to be sold for higher value applications. Furthermore, the lowest production costs, overall the analysis, were obtained when eucalyptus, pine and macauba were used as feedstocks together with hydrothermal liquefaction or fast pyrolysis (with hydro-processing in the case of Macauba oil). These scenarios resulted in minimum selling price of around 620 to 870 US$/ton biojet. All of these scenarios resulted in a GHG emissions reduction of around 50-70% with respect to the fossil based jet fuel.
In the case of the marine biofuel production, the total production costs were estimated to be around 3.2-11.2 times higher than the costs of the fossil based marine gas oil. Furthermore, the GHG emissions were estimated in the range of -36kg/GJ to 96kg/GJ (HFO: 89kg/GJ). This large is also due to the application of different models for biogenic CO2 accounting.
The methodology here presented builds up on the combination of early-stage analysis , techno-economic evaluation , parametric analysis for combined techno-economic and environmental assessment [3-4], for integration of the three pillars of sustainability during the early-design stages of sustainable biorefineries [5-7].
