Metal hydrides provide a safe and very often reversible way to store energy that can be accessed after hydrogen release and its further oxidation. To be economically feasible, the metal or alloy used for hydrogen storage has to exhibit high hydrogen storage capacity, low temperature of the hydrogen release, and be low cost.

DOE Explains...Batteries. Batteries and similar devices accept, store, and release electricity on demand. Batteries use chemistry, in the form of chemical potential, to store energy, just like many other everyday energy sources. For example, logs and oxygen both store energy in their chemical bonds until burning converts some of that chemical ...

To charge, renewable electricity heats the metal oxide pellets from 1000-1500°C, triggering a chemical reaction that releases oxygen and stores heat in the form of chemical energy. Later, when stored energy is needed, air is directed through the module and the metal oxide consumes oxygen to reverse the reaction and release heat to the air.
