One of the most promising technologies for storing energy is the production of hydrogen through water electrolysis powered with renewable energy sources and its storage. There are different ways to stored hydrogen but the most efficient and safe is as solid metal hydride since it has no compression and liquefaction costs. The hydrogen storage system filled with a low equilibrium pressure hydride-forming alloy can be charged quickly by using a hydrogen generator. This hydrogen can be used later to power a H2/Air PEM fuel cell for obtaining electricity efficiently. In this work, the behavior of an integrated system consisting in a PEM hydrogen generator and a low pressure hydrogen storage system is studied.
