Table 1 (with references) presents the energy required for storage of hydrogen at three different conditions (350 bar, 700 bar, 1 bar at 20 Kelvin). Of particular note are the very modest theoretical storage energies. Compressing hydrogen (isothermally) from 20 bar
In the hydrogen energy storage system, the hydrogen is produced by the electrolyzer and stored in a hydrogen storage tank (HST) during periods of sufficient power while the fuel cells convert hydrogen to electricity power when the power is insufficient [58].
