Does risk information change the acceptance of hydrogen refueling stations in the general Japanese population?

摘要

Hydrogen refueling stations (HRSs) are inevitable infrastructure for the utility of fuel cell vehicles, but they can raise people's safety concerns. We analyzed whether information on the risk/safety measures changed people's acceptance of HRSs. Respondents were provided those information and asked to rate their acceptance of an HRS placement either beside their home or at the gas station closest to their home. The respondents' perception of the risk of HRSs and their attitudes on environmental issues are analyzed by factor analyses. The results show that provision of the quantitative risk information and risk acceptance criteria increased the acceptability of HRS in proximity to the homes of respondents (P 0.1) but decreased the acceptability of HRS at the nearest gas station. Factor analyses suggest that risk information on HRS alleviates the respondents' feelings of dread or uncertainty, leading to better acceptance. Our study should promote improved risk communication prior to HRS installation. (C) 2019 Hydrogen Energy Publications LLC. Published by Elsevier Ltd. All rights reserved.
