Nowadays, problems associated to greenhouse gases emission and fuel ending, makes that renewable energy sources and hydrogen technology have high interest for governments and researchers, and become an option for an environmental sustainable world.

Renewable energy sources, like solar energy and wind energy, have been used for the last three decades. Researchers and companies have improved the efficiency of this kind of systems, but they have a problem due to energy source temporality that does a fluctuation in systems power output. This fluctuation makes that sometimes energy demand is higher than energy produced by the system and vice versa. Hydrogen Technology may solve this problem.

In full-paper, a wind-hydrogen installation will be described. Also, its behaviour versus different electric demand will be studied.
