You should calculate weight and volume hydrogen storage capacities of a standard steel gas cylinder (weight 50 kg, volume 50 L, hydrogen pressure 200 bar), as well as theoretical mechanical work for the filling of this cylinder with hydrogen compressed from atmospheric pressure to the storage pressure. All the calculations have to be done for a real gas assuming room temperature (25 °C).
