Abstract
The focus of this study was to examine the current situation of natural gas vehicles and to propose about natural gas vehicles (NGVs) popularization. Although the utilization of natural gas vehicles has been increasing rapidly, the number was only 0.01% of total vehicles in use in Japan. The main user of NGVs was not an individual but a gas company and a local government. Young drivers are interested in NGVs, but they do not have much knowledge of NGVs. It is needed to promote the popularization of NGVs through a deeper understanding of NGVs by improving knowledge and
disseminating information.
