A Study on the Priority of Advancing Hydrogen Fueling Infrastructure Using AHP

Abstract

In this study, the solution to the problems raised in the hydrogen industry infrastructure construction was considered using the AHP analysis. This research model divided the major decision-making issues of hydrogen infrastructure construction into seven and evaluated the importance and priority of detailed items for each decision-making issue. The result of the analysis indicated that locations near existing gas stations were suitable for installing hydrogen refueling stations. To expand the supply of hydrogen refueling stations, safety concerns and acceptability of the refueling stations were evaluated as the biggest problems to be solved. It was evaluated that the location near the new mass demand was the most suitable location of the hydrogen production facility. Expanding public service advertisements related to hydrogen safety was found to be an appropriate technique for raising public awareness for the expansion of hydrogen infrastructure construction. Insufficient hydrogen infrastructure was evaluated as the most important factor for expanding the hydrogen industry ecosystem in Korea. Therefore, to expand the construction of hydrogen infrastructure, in addition to the subsidies for hydrogen vehicles, support policies from the government that guarantee a certain rate of return on the operation of hydrogen infrastructure facilities are necessary.
