Transportable is the fail.
Even LPG has 500 times energy
less compression ratio, thinner, smaller tanks.

Man has tried for 100 years to use H
after all it is so common in the universe.

The bonds between H and O are so strong
there is always more energy expended in
separating than gained in combining
in fuel cell or combustion
The term for this is valency
Physics dictate otherwise.

I may be contradicted - pride only.
but it cannot be done
pushing water uphill with toothpick.
Remember valency.
