  7. Abstract:
  8. The potential future use of hydrogen as a transportation fuel must be evaluated from a supply chain perspective. However, the main challenge in motivating the hydrogen supply chain network is the lack of existing hydrogen infrastructure. Strategic decisions for planning sustainable infrastructure can be analyzed hierarchically in time-related stages (2025-2030-2035). Meanwhile, a time- and location-based design has been specifically applied to a few selected ports in southern Iran, with limited focus on a national or countrywide scale. This study proposes a mixed-integer linear programming (MILP) optimization model to logically design the hydrogen supply chain, considering primary energy resources (natural gas, coal, biomass, electricity, and water), production technologies (steam methane reforming, coal gasification, biomass gasification, and water electrolysis), transportation methods (tanker trucks, tube trailers, and pipelines), and types of storage technologies (cylindrical and spherical tanks). The research aims to meet the fuel demand of inbound and outbound ships at selected ports in the form of hydrogen, determining the type of production, transportation, and storage technologies, as well as the size and number of infrastructures and the optimal locations for their establishment among the ports. The results of this study indicate which ports will produce hydrogen domestically and which ports will import the required hydrogen from other ports based on demand. The optimization was evaluated in two scenarios, considering total daily costs and carbon taxes to account for environmental impacts, with the results presented for three different time periods in each scenario. The results of Scenario 1 indicate that the cost of hydrogen per kilogram is $7.11 in the first period, $5.63 in the second period, and $4.46 in the third period. In Scenario 2, which includes carbon taxes, the cost of hydrogen per kilogram in the three periods is $13.23, $10.65, and $9.21, respectively. Ultimately, the proposed design can assist policymakers in selecting sustainable pathways for dynamic hydrogen development planning
