Hydrogen Storage Figure 2
storage still remains as a key roadblock. Hydrogen has a low energy density. While the energy per mass of hydrogen is substantially greater than most other fuels, as can be seen in Figure 1, its energy by volume is much less than liquid fuels like gasoline. For a 300 mile driving range, an FCEV will need about 5 kg of hydrogen. At 700 bar (~10,000
