Pressure tanks as with gaseous storage can be saved. Instead, you basically need huge thermos bottles, because liquid H2 has to be stored at around 250 degrees below zero, otherwise it becomes gaseous (boiling point is -252 degrees Celsius). This is relatively uncomplicated, so you don’t need a refrigerator in the tank system. During operation, the amount of hydrogen that is needed is heated so that it flows out of the tank into the fuel cell. Everything else is identical to the drive just described, i.e. the same fuel cell/battery setup, the same motors.
