1. Introduction. Hydrogen has the highest energy content per unit mass (120 MJ/kg H 2), but its volumetric energy density is quite low owing to its extremely low density at ordinary temperature and pressure conditions.At standard atmospheric pressure and 25 °C, under ideal gas conditions, the density of hydrogen is only 0.0824 kg/m 3
The hydrogen storage level is higher in case 2, but its storage size is still low (see Table 3) and the battery is responsible for storage. In case 3, hydrogen storage contribution is more considerable while battery size is reduced.
