Abstract
With the emergence of new technologies that enable the production of renewable hydrocarbon fuels, the production of sustainable alternative jet fuel has become feasible. To encourage adoption of these technologies and fuels, future policy initiatives are expected to drive new demand for sustainable alternative jet fuels. In response to these initiatives, and in response to other national and regional interests, this study provides an analysis of an oilseed-to-sustainable-alternative-jet-fuel supply chain for the United States Pacific Northwest. This research is separated into two components. The first research component quantifies oilseed feedstock in addition to chemically-similar fats, oils, and greases that can also be used to produce fuel. Oilseeds are quantified for future production potential using a high-resolution approach based on compatibility with current crop rotations and expected oilseed yields. Fats, oils, and greases are quantified using population data from large cities and capacities from major slaughterhouses. The second research component uses a transshipment model, constructed and solved as a mixed-integer linear program, to analyze the oilseed-to-sustainable-alternative-jet-fuel supply chain from the production of lipid feedstock to a biorefinery that uses the hydroprocessed esters and fatty acids process. The model has several steps including: feedstock production, short-term storage, long-term storage, oil extraction, and final markets. In addition to fuel markets, the model also includes oilseed meal markets. The most cost-efficient oilseed crusher location combinations are selected by the model solver from an array of possible locations. Multiple model scenarios are used to study varied feedstock scenarios and biorefinery combinations. The results from this study suggest that, under a maximum production scenario, sufficient lipid feedstocks could be sourced from within the Pacific Northwest to supply an existing biodiesel plant and a new biorefinery with jet fuel capacity. The most efficient supply chain operations would require two or three new oilseed crushing facilities located near oilseed production areas.
