Abstract
Hydrogen, which is expected to be a popular type of next-generation energy, is drawing attention as a fuel option for the formation of a low-carbon society. Because hydrogen energy is different in nature from existing energy technologies, it is necessary to promote sufficient social recognition and acceptability of the technology for its widespread use. In this study, we focused on the effect of initiatives to improve awareness of hydrogen energy technology, thereby investigating the acceptability of hydrogen energy to those participating in either several hydrogen energy technology introduction events or professional seminars. According to the survey results, participants in the technology introduction events tended to have lower levels of hydrogen and hydrogen energy technology knowledge than did participants in the hydrogen-energy-related seminars, but confidence in the technology and acceptability of the installation of hydrogen stations near their own residences tended to be higher. It was suggested that knowledge about hydrogen and technology could lead to improved acceptability through improved levels of trust in the technology. On the other hand, social benefits, such as those for the environment, socioeconomics, and energy security, have little impact on individual levels of acceptance of new technology.

We focused on the effect of initiatives that aim to promote awareness of hydrogen energy technology, investigating the acceptability of the technology by participants at several hydrogen energy technology introduction events
In order to improve the ease of response, we asked that fuel cell vehicles (FCVs) be compared to internal combustion engine vehicles and that hydrogen stations (HSs) be compared to regular gas stations
Summary
Hydrogen is attracting attention as a next-generation energy source; it is a useful option for creating a decarbonized society [1]. Test drive experiences of electric vehicles have proved to be useful for greatly changing the introductory barriers and technology recognition, and it has been reported that providing public experiences of technology is a useful strategy [10,11,12] Such information provision and experiences have been shown to be effective for ordinary people who are not yet widely familiar with the technology [13]. Ono et al [24] investigated the acceptability of installing hydrogen refilling facilities in the existing gasoline stations and showed that “fear”, one of the risk awareness factors, was the most influential factor as an independent variable contributing to acceptability Based on this finding, they further investigated the impact of the provision of risk information on the acceptability of HSs as a measure to reduce fear [25]. We focused on the effect of initiatives that aim to promote awareness of hydrogen energy technology, investigating the acceptability of the technology by participants at several hydrogen energy technology introduction events
