What is the easiest way to extract hydrogen from water and the safest way to store it?
by

1 Answer

Answer :

Electrolysis (which means splitting using electricity) of water is the method for producing hydrogen  from water. The safest way to commercially store it would be to use a palladium “sponge”, because  palladium adsorbs several hundred times it’s own volume in hydrogen. One would need to produce a  compound with a very high surface area, which has a thin coating of palladium. This type of material is  commonly used as a catalyst in chemical processes.
