Absolutely!! It has to be the way ahead. Hydrogen is produced by electrolysis of water and is a great way of effectively storing electricity. the hydrogen can then be stored by absorbing it onto special metal sponges made of metals such as palladium and then can be used in fuel cells to generate power. The by-product of all this is water which is what we started with. The technology to use hydrogen is now advanced enough that hydrogen powered cars are commercially available and the technology can only get better.
