“…In material-based hydrogen storage systems, the hydrogen can be stored in two forms: (i) physical adsorption on the material and (ii) stored through chemical bonds [79,80]. Among the different hydrogen storage materials, magnesium (Mg) has been considered one of the excellent materials for hydrogen storage material because of its different forms in hydrides [81][82][83][84]. Mg can be formed as intermetallic, elemental and complex hydrides, such as magnesium hydride (MgH 2 ) [85,86], Mg 2 NiH x [87,88], Mg(AlH 4 ) 2 [89,90] and Mg(BH 4 ) 2 [91][92][93][94].…”

In the present scenario, much importance has been provided to hydrogen energy systems (HES) in the energy sector because of their clean and green behavior during utilization. The developments of novel techniques and materials have focused on overcoming the practical difficulties in the HES (production, storage and utilization). Comparatively, considerable attention needs to be provided in the hydrogen storage systems (HSS) because of physical-based storage (compressed gas, cold/cryo compressed and liquid) issues such as low gravimetric/volumetric density, storage conditions/parameters and safety. In material-based HSS, a high amount of hydrogen can be effectively stored in materials via physical or chemical bonds. In different hydride materials, Mg-based hydrides (Mg–H) showed considerable benefits such as low density, hydrogen uptake and reversibility. However, the inferior sorption kinetics and severe oxidation/contamination at exposure to air limit its benefits. There are numerous kinds of efforts, like the inclusion of catalysts that have been made for Mg–H to alter the thermodynamic-related issues. Still, those efforts do not overcome the oxidation/contamination-related issues. The developments of Mg–H encapsulated by gas-selective polymers can effectively and positively influence hydrogen sorption kinetics and prevent the Mg–H from contaminating (air and moisture). In this review, the impact of different polymers (carboxymethyl cellulose, polystyrene, polyimide, polypyrrole, polyvinylpyrrolidone, polyvinylidene fluoride, polymethylpentene, and poly(methyl methacrylate)) with Mg–H systems has been systematically reviewed. In polymer-encapsulated Mg–H, the polymers act as a barrier for the reaction between Mg–H and O2/H2O, selectively allowing the H2 gas and preventing the aggregation of hydride nanoparticles. Thus, the H2 uptake amount and sorption kinetics improved considerably in Mg–H.

“…Generally, H 2 can be stored by different strategies including liquefaction method, [ 6 ] compression in gas cylinders, [ 7 ] adsorption on solid‐state materials, [ 8 ] solid form as chemical hydrides, [ 9 ] and using metastable alloys which can absorb/desorb H 2 with faster kinetics at low temperature. [ 10 ] For the onboard applications, H 2 storage capacities should fulfill the goals set by the United States Department of Energy (US DOE).

Moreover, burning fossil fuels intensifies the emission of greenhouse gases causing catastrophic climatic change. [1] Therefore, an alternative renewable energy with no greenhouse gases emission is highly needed. In this framework, hydrogen (H 2 ) is considered as a promising candidate for carbon-free energy production. [2] Additionally, H 2 is inexhaustibly abundant in nature and endowed with the intriguing features such as the lightest weight in the periodic table and generates high chemical energy of 142 MJ kg −1 per unit mass; about three times greater than the energy produced (47 MJ kg −1 ) by burning hydrocarbons. [3,4] Therefore, continuous efforts are being devoted to replace the conventional liquid hydrocarbon-driven socioeconomic system to hydrogen economy, which embraces the generation of H 2 , its storage, and ultimately energy transfer. [5] However, finding the efficient and economical means of H 2 storage is still a major challenge to be addressed before the practical implication of hydrogen economy. Generally, H 2 can be stored by different strategies including liquefaction method, [6] compression in gas cylinders, [7] adsorption on solid-state materials, [8] solid form as chemical hydrides, [9] and using metastable alloys which can absorb/desorb H 2 with faster kinetics at low temperature.

Hydrogen energy is an excellent carrier for connecting various renewable energy sources and has many advantages. However, hydrogen is flammable and explosive, and its density is low and easy to escape, which brings inconvenience to the storage and transportation of hydrogen. Therefore, hydrogen storage technology has become one of the key steps in the application of hydrogen energy. Solid-state hydrogen storage method has a very high volumetric hydrogen density compared to the traditional compressed hydrogen method. The main issue of solid-state hydrogen storage method is the development of advanced hydrogen storage materials. Metal borohydrides have very high hydrogen density and have received much attention over the past two decades. However, high hydrogen sorption temperature, slow kinetics, and poor reversibility still severely restrict its practical applications. This paper mainly discusses the research progress and problems to be solved of metal borohydride hydrogen storage materials for solid-state hydrogen storage.
