Fuels for automobiles are such as gasoline, diesel, liquefied petroleum gas (LPG) and compressed natural gas (CNG). These fossil fuels are limited the deposits and emit carbon dioxide leading to the global warming issue. Hydrogen as the fuel for automobiles is an energy carrier produced by all kinds of primary energy sources including renewable energy. Fuel cell vehicles can use hydrogen with very high efficiency and without carbon dioxide emission. This paper gives an outline of energy pass of automobile fuels from a point of view of carbon free energy system, the methods of on board hydrogen storage systems from a point of view of cost, compactness, light weight and convenience, and safety property of hydrogen.
