Abstract
The following four key factors are essential and must be assured for achieving the widespread use of natural gas vehicles (NGVs, focusing on compressed natural gas vehicles (CNGVs) in this project): safety and reliability of NGVs, gas quality and a stable supply, economic benefits for users, and user convenience. This project aims to show the importance of these factors and consists of three pillars: (1) construction and operation of refueling stations (using Japanese technologies), (2) operation of CNG vehicles (10 passenger cars and 18 trucks made by original equipment manufacturers), and (3) institutional design support (providing policy recommendations based on the data and information obtained from the demonstration).
