not only lowers the energy consumption but also lowers the cost of production. Finally, this integrated solution enables projects to have shorter project execution timelines, as JM and Honeywell UOP have worked together to align battery limit conditions and standard deliverables. The integrated approach is ideal for projects that have access to low-cost renewable power (<$40/MWh), biogenic CO₂ or biomass sources, and a final market for jet fuel. In the US, the HIF eSAF facility adopts a co-located methanol and MtJ model, producing e-methanol through JM’s eMERALD technology. This e-methanol is then transformed into eSAF utilising Honeywell UOP’s eFining technology. This project highlights the benefits of integrating the licensed technologies of these companies to provide a unified interface for customers. This integrated approach combines key elements that enhance bankability and streamline the project deployment process, thereby adding value and reducing costs, particularly in the conversion of CO₂ and hydrogen to jet fuel. Conclusions When evaluating routes to MtJ production and the hub-and-spoke model versus an integrated solution, several factors come into play. The hub-and-spoke model might be more advantageous in regions where there is an abundance of renewable electricity and scattered sources of CO₂. This model allows for the production of methanol at multiple points, which can then be transported to a central location for conversion into SAF. This approach leverages the benefits of economies of scale, reducing the overall cost of production and increasing efficiency. Conversely, the integrated approach may be more appropriate for projects that have a consistent and concentrated supply of renewable power and biogenic CO₂, as well as a nearby market for jet fuel. This method reduces operational complexity by consolidating processes into a single location, streamlining production, and minimising logistics costs. Integrated projects can also offer a unified interface for customers, enhancing commercial

Ultimately, the choice between the hub-and-spoke model and the integrated solution depends on the specific circumstances of each project, including the availability of resources, infrastructure, and market demand. By carefully assessing these factors, stakeholders can determine the most “ The integrated approach is ideal for projects that have access to low- cost renewable power (<$40/MWh), biogenic CO₂ or biomass sources, and a final market for jet fuel ” cost-effective and efficient approach to methanol-to-SAF production, ensuring sustainable and scalable outcomes. The collaboration between JM and Honeywell UOP demonstrates the potential of MtJ technology in producing SAF. With proven and commercialised technologies, this initiative offers a reliable and efficient pathway for SAF production. eMERALD, HyCOgen, and FT CANS are trademarks of Johnson Matthey. eFining is a trademark of Honeywell UOP.
