I hadn’t thought of it before but it’s obvious, hydrogen is a gas at room temperature, it had to be stored under pressure in order to get any significant mass into the volume of a tank. So it’s under pressure in the refueling station and in the car’s tank. How does it get from one to the other without boiling away?
