Abstract
The popularity of hydrogen refueling stations in China is hindered by unreasonable site selection and high initial costs. Built gas stations with large consumer groups and reasonable locations can be expanded into oil-hydrogen combined stations. which can effectively reduce construction costs and approval complexity, improve hydrogenation infrastructure and reduce hydrogenation costs. Taking Chinese social-economic environment into consideration, this paper created an optimal site selection decision framework for oil-hydrogen combined stations to achieve the goal of reducing construction costs, transportation costs and carbon emissions in the whole process. A two-stage criteria system including veto criteria system and evaluation criteria system was established, and fuzzy analytic hierarchy process (AHP) method and TOmada De decis ão Interativa Multicritério (TODIM) method were utilized to determine the criteria weight and obtain the ranking of alternatives respectively. Finally, a case study was conducted and the most suitable gas station site for the construction of oil-hydrogen combined station was determined. Moreover, the economics of the several hydrogen sources were discussed from the perspective of best site selected, it is concluded that hydrogen from natural gas or coal is still the best hydrogen source for oil-hydrogen combined stations.
