What does this research mean for the field?

Integrating supply chain logistics with process-level optimization for sustainable aviation fuel production reveals that an intermediate production capacity (120,000–300,000 tSAF/year) is optimal, contrasting with decoupled models that incorrectly favor maximum capacity. Novelty: ClaimNovelty.METHODOLOGICAL. Consensus alignment: ConsensusAlignment.NEUTRAL.

Overview

Computational modeling reveals optimal intermediate production capacities for alcohol-to-jet fuel systems, indicating trade-offs between supply chain costs and conversion efficiency.

Key Points

Develop an integrated multiscale optimization framework combining biomass supply chain logistics with an intensified Alcohol-to-Jet (ATJ) conversion process to evaluate sustainable aviation fuel production.
Coupled a multi-period mixed-integer linear programming (MILP) supply chain model with an Aspen Plus simulation of an intensified ethanol-to-ATJ upgrading process involving dehydration, oligomerization, hydrogenation, and reactive distillation.
Optimized the conversion process via Differential Evolution with Tabu List (DETL) and fed yields, costs, and environmental impacts back into the supply chain model using sugarcane bagasse feedstock in Mexico targeting Mexico City Airport.
Decoupled supply chain optimization favored larger scales, lowering total annualized cost from ~1010 to 340 USD/tSAF and Eco-Indicator 99 (EI99) from 1.110 to 1.059 kPt/tSAF as capacity expanded from 80,000 to 490,000 tSAF/year.
Isolated ATJ process optimization reduced process-only EI99 nonlinearly from ~1.70 to 0.55 kPt/tSAF.
The integrated multiscale framework identified an optimal intermediate operating region of 120,000–300,000 tSAF/year, with total annualized costs of ~3400–6800 USD/tSAF and total EI99 values of ~0.78–1.31 kPt/tSAF (1.063 kPt/tSAF at the 200,000 tSAF/year base case).
