The use of Hydrogen as fuel raises many comments, both for and against. Numerous experts endorse it by assuring that, despite being a very volatile and flammable gas, it does not present greater risks than other fuels such as gasoline, and by using surplus renewable energies for its production from water, it would be generating a clean energy and with affordable costs. This is possible because at present, for example, the wind turbines of the wind power plants stop when it is not possible to consume all the generated energy, which should be stored in gigantic facilities with storage batteries. These batteries, in addition to occupying a large space, are affected by changes in humidity and temperature. If, instead of using these batteries, that «surplus» electricity is used to produce hydrogen, this gas can be stored indefinitely, and once it is used as fuel, the only residue obtained is water.
