Abstract

Research related to hydrogen technology is being actively conducted around the world. Korea is also making great efforts to develop technology to leap forward as a hydrogen economy powerhouse. In particular, the world's No. 1 hydrogen vehicle penetration rate is proof of this. However, the construction of hydrogen refueling stations is being delayed. The biggest delay factor is the public opposition. As such, policies without public support cannot be successfully implemented and are not sustainable. Therefore, this study intends to analyze the factors affecting the acceptability of hydrogen refueling stations in favor of and against them. As a research method, the basic factors affecting acceptability were identified by reviewing previous studies, and a questionnaire was designed and investigated based on the established factors. The validity and reliability of the questionnaire were verified, and the hypothesis was verified through correlation analysis. And, using structural equation modeling, a factor model was developed on the acceptability of hydrogen refueling stations. As a result of the study, acceptability defined private acceptability and public acceptability. In the case of private acceptability, it was confirmed that the higher the attitude toward the environment, the higher the level of knowledge about the hydrogen charging station, and the lower the degree of feeling the risk of the hydrogen charging station, the higher the acceptability. In the case of public acceptability, it was confirmed that the higher the benefit, the better the attitude toward the environment, and the lower the risk-taking characteristics of the individual, the higher the acceptability. Therefore, in this study, based on the potential factors verified in previous studies, the main factors affecting the acceptance on hydrogen refueling stations were identified. And the acceptance model was developed using structural equation modeling. This study is expected to provide basic data to seek ways to improve the acceptance of public when implementing national policies such as hydrogen refueling stations, and to be used analysis data for scientific communication.

수소 기술과 관련된 연구는 전 세계적으로 활발하게 진행되고 있다. 우리나라도 수소경제 강국으로 도약하기 위해 기술개발에 많은 노력을 기울이고 있다. 특히, 세계 수소차 보급률 1위가 그 증거이다. 그러나 수소차의 인프라인 수소충전소 구축이 지연되고 있다. 지연요인은 대중들의 반대가 가장 크다. 이와 같이, 대중들의 지지를 받지 못한 정책은 성공적으로 실현될 수 없고, 지속가능하지 않다. 따라서 이 연구에서는 수소충전소를 찬성하고 반대하는 수용성에 미치는 요인을 분석하고자 한다. 연구방법으로는 선행연구를 검토하여 수용성에 미치는 기초요인을 파악하였고, 설정된 요인을 바탕으로 설문을 설계하고 조사하였다. 설문에 대한 타당도와 신뢰도를 검증하였으며, 상관분석을 통해 가설을 검증하였다. 그리고, 구조방정식 모델링을 사용하여 수소충전소 수용성에 미치는 요인 모델을 개발하였다. 연구 결과로 수용성을 사적수용성과 공적수용성으로 구분하였으며, 사적수용성의 경우에는 환경에 대한 태도와 수소충전소에 대한 지식의 정도가 높을수록, 수소충전소에 대한 위험을 느끼는 정도가 적을수록 수용성이 크다는 것을 확인하였다. 그리고 공적수용성의 경우에는 이익이 많고, 환경에 대한 태도가 좋을수록, 위험을 감수하는 개인의 특성이 적을수록 수용성이 크다는 것을 확인하였다. 이 연구를 통해 수소충전소 등 국가정책 시행 시 주민들의 수용성 제고 방안을 모색하는 기초자료로써 제공하고, 과학적인 소통의 분석자료로 활용될 것을 기대한다.
