Hydrogen (gas) is H
2 not HHO...
HHO is the
fringe science name for
oxyhydrogen, a mixture of 2 molecules of hydrogen (H
2) per molecule of oxygen (O
2) that occurs from the electrolysis of water.
For several reasons it is not doable to store oxyhydrogen in large quantities.
Applications that do burn hydrogen and oxygen store them in separate tanks. Preferably you only store the hydrogen and derive the oxygen from the air.
A full tank of hydrogen for a car would weigh just a few kilos.
(the contents that is; the tank itself would weigh much more!)
The oxygen needed to burn the hydrogen weighs 8 times as much.
