The connectivity between hydrogen and metal atom at interstitial site is mainly responsible for the hydrogen storage. In metal hydride batteries, hydrogen storage alloys chiefly work as negative electrode. Various types of metal alloys can be used for this purpose.
International Energy Agency, Task 32 “Hydrogen-based Energy Storage”. Hydrogen storage in porous materials, metal and complex hydrides. Applications of metal hydrides for MH compression, thermal and electrochemical storage. Hydrogen energy systems using metal hydrides.
Conventional methods to store hydrogen involve compression of gas and liquefaction [ 109 ]. However, due to the safety problems involved with these methods, alternatives are looked for hydrogen storage. There was development of solid-state material for hydrogen storage [ 110 ]. Materials are absorbed or adsorbed on these materials.
The most extensively studied and often utilized solid-state hydrogen storage material is metal hydride. Chemically bonded hydrides are divided into three categories: (i) non-reversible complex hydrides, (ii) non-metal hydrides, and (iii) metal hydrides.
Different hydrogen storage approaches include using high pressure, compressed gas, cryogenic liquid hydrogen storage, solid state and electrochemical [ 102 ]. Solid-state hydrogen storage easily done in materials like metal hydrides, complex hydrides, carbon containing materials like activated carbon, graphene and carbon nanotubes [ 103 ].
Chen et al. conducted an economic analysis of a renewable energy system using hydrogen produced by water electrolysis as an energy carrier to overcome the fluctuation of renewable sources. It was determined that a hydrogen-based energy storage system (ESS) is more advantageous economically than a conventional battery storage system.
