A great way to store hydrogen i sto chemically combine it with oxygen. The hydrogen thus stored is nontoxic* and nonflammable, and can easily be liberated by the simple addition of elemental sodium, an element in non-toxic* table salt.

*Dihydrogen monoxide has been linked to deaths by inhalation, and salt has been linked to heart disease.

Dihydrogen monoxide

Oooh, yikes! That sounds like nasty stuff! ;)

Dropping some lye and some aluminum foil into the Dihydrogen monoxide will also liberate the Hydrogen. The biggest problem is for wicked witches who will be unable to safely work at the factories as exposure to Dihydrogen monoxide has been known to melt witches.

The problem is that the energy cost of making Na is greater than that recovered from burning the H2 evolved. Again a big storage battery. The interesting aspect to me is that density is a huge problem with H2; even as a liquid it is 11 times less dense than gasoline. In fact, it liberates less energy per unit mass than gasoline (but more per pound). So if H2 could be stored at densities approaching that of water or water ice, it may open up some applications.
