In the present era, due to the growing demand for energy resources as well as environmental requirements, challenges in the field of energy supply have been created. Among renewable energy systems, hydrogen-based systems are considered as one of the promising options on the path to clean fuel usage due to the lack of greenhouse gas emissions during combustion. In this study, to investigate the development of the use of hydrogen as a fuel used in the transportation sector, a hydrogen supply chain network design model has been proposed.
The model presented in this research is a mixed linear integer programming which in the first stage determines the configuration of hydrogen supply chain infrastructure including production, storage, distribution and refueling sites in terms of number, technology and place. The establishment has been developed in accordance with the uncertain parameter of hydrogen demand by considering the two objective functions of cost minimization and carbon minimization emitted along the network. In order to boost responsiveness of the network configuration to the uncertainty in the hydrogen demand parameter, feasibility based Robust possibilistic programming method has been used. Weighting method has also been used for multi-objective modeling. In the second stage, the possibility of exporting hydrogen to regional countries through the excess production capacity of network equipment has been investigated. The third function studied for this important issue is the maximization of profits from hydrogen exports. The results of the case study on Iran show that by imposing a small tax on the emitted carbon unit, the percentage of carbon production is greatly reduced.
Optimal technology for hydrogen production is coal gasification with carbon capture and emission facilities. Hydrogen production with the aim of exporting from the surplus of hydrogen production capacity is not economical due to the high cost of hydrogen production unit and will be cost-effective only by reducing the cost hydrogen production unit.
