When compressed, the density of hydrogen at 35.0 MPa is about 23 kg/m 3 and at 70.0 MPa is about 38 kg/m 3. This leads to an energy density of 767 kWh/m 3 (27 °C, 35 MPa). The volume of the storage tank is the biggest challenge, since the density of compressed hydrogen is lower than that of liquid hydrogen.
