Hydrogen as a clean energy can be stored, delivered, and distributed on a large scale in the form of high-pressure gaseous hydrogen, liquid hydrogen, organic liquids, etc., has emerged as the most promising energy option to address energy and environmental problems. As the hydrogen technology matures, the biggest problem facing the development of the hydrogen energy industry is the constraints caused by the inadequate hydrogen energy infrastructure. Improving the inadequacy of the existing hydrogen infrastructure and design a new and complete hydrogen supply chain (HSC) has become an urgent problem. In this paper, we propose a new model for designing a HSC in China using a mixed integer linear programming approach. This model introduces organic liquids as an alternative option for hydrogen transportation and storage, and incorporates the dehydrogenation process into the HSC. Based on the energy endowment of different regions in China, we optimize the model with three single-objective functions (total daily costs, daily CO2 emissions, and total daily costs with carbon tax) and two multi-objective functions (Ε-constraint method and weighted summation method), taking into account the cost and carbon emissions. The possible states of the hydrogen supply chain network in China are predicted, as well as the impact of carbon tax changes on the HSC design is explored. The results indicate that the hydrogen cost is between 3.854 and 8.121 $/kg. When considering the carbon tax and CO2 emissions, hydrogen is transported and stored in the form of organic liquid, suggesting that incorporating organic liquid can effectively reduce the total carbon emissions generated by HSC. The HSC is significantly impacted by the carbon tax, therefore, a reasonable carbon tax policy is crucial to the design of HSC. © 2024
