Hydrogen tank is essentially a battery and not an efficient one either in terms of space or energy. If we have excess electricity then I think it is a great way to store energy on a mass scale even when the efficiency is relatively poor. It is nearly 100% clean if atom splitting is done via electricity.
What doesn't make sense is producing, compressing into tanks, transporting, pumping into tanks again, pumping into the tank in your car. For giant ships and the like makes way more sense to me.
