  1. You seem to be missing just how hard it is today to make a good hydrogen tank. With our currently available technology, spare hydrogen tank is not going to happen. In addition, hydrogen has such a tiny molecules that leaking through the wall of the tank is a real problem. You simply cannot make a portable tank that you fill once and throw in your trunk for future comsuption in case your main tank gets empty. See https://en.wikipedia.org/wiki/Hydrogen_storage for extra details. Notice, for example, that pure liquid hydrogen has less hydrogen per volume than gasoline!
