Luckily hydrogen floats upwards pretty quickly. So paradoxically, storage tanks are safer the less protection they have around them. Or at least, above them.

    Just as well trains and other vehicles don't have roofs then.

    Fun fact: Unlike natural gas, which needs enough oxygen and enough gas to explode, hydrogen is explosive at almost any concentration of hydrogen and oxygen!

    Boom! Woohoo!
