Abstract:
This study evaluates the production of Sustainable Aviation Fuel (SAF) from Municipal Solid Waste (MSW) through gasification with Fischer-Tropsch (FT) and Methanol-to-Jet (MTJ) production pathways. The process employs the integrations of carbon capture and storage (CCS) and green hydrogen (H2) as system integrations. Integration of CCS offers additional carbon mitigation, benefiting from credits tied to the biogenic carbon in MSW. The H2 integrated processes benefit from improved productivity and efficiency, as well as utilisation of the oxygen produced from water electrolysis in the gasification and reforming stages. The processes are modelled within Aspen Plus and based on the detailed mass and energy balances obtained, a techno-economic assessment of the different production pathways is carried out. Refuse-derived fuel (RDF) derived from MSW is used as the feedstock for syngas generation, resulting in a hydrogen-rich, contaminant-free gas for synthesis. Results and assessment show the MTJ-H2 pathway achieving the highest SAF yield and lowest levelized cost of production (LCOP) compared to other pathways. Sensitivity analysis was also carried out on some key variables to assess their impacts on LCOP. Overall, the findings will underscore the importance of exploring various pathways and integrations, as well as industry collaboration for scaling up in order to advance waste-based SAF technologies, ensuring their role in the future energy mix for SAF and decarbonisation.
