Abstract
The total number of vehicles fuelled with compressed natural gas, CNG, is relatively very small in comparison to gasoline fuelled vehicles. Accordingly, because of the lack of statistics of accidents involving CNG fuelled vehicles, their safety aspects are evaluated in comparison to automobiles fuelled with gasoline or some other alternative fuels such as propane, hydrogen, LNG or LH2. It is suggested that methane, CNG, has some excellent physical, chemical and combustion characteristics that make it a safe automotive fuel. These characteristics are reviewed and the superior relative safety of methane in automotive applications in comparison to applications involving the other fuels is demonstrated where well designed conversion systems and operations are employed.
