The hydrogen possesses high calorific value and it is necessary to utilize this energy due to current energy based resources depletion. It elaborates the paramount importance of hydrogen as a future renewable fuel. There are used different techniques for hydrogen storage and its transportation. In transportation techniques, there are high pressure compression and liquefaction from pipelines. On the other hand, there is developed an optimized model which fulfills the challenges by regarding hydrogen transportation with its low cost. The prominent practiced hydrogen storage techniques are; Adsorption, Casting on alloys, Absorption and Metal hydride reactor. These techniques can store hydrogen from 1.28 wt. % to 19.6 wt.%. Hence, the need to transport hydrogen through storage has become possible by attaining the challenges. It is an unprecedented and welcomed result declaration with highly precise evaluation

Summary The combination of a metal hydride (MH) with a water pump has gained significant interest recently. However, the efficiency of such a system is low, as it requires a substantial quantity of heat from an external source to initiate the desorption process. Storing the heat generated by the absorption reaction (exothermic reaction) in a phase change material (PCM) and reusing it during the dehydration reaction (endothermic reaction) is a viable method to enhance the pump's efficiency. Thus, in the present study, the mathematical modeling and numerical simulation of a new configuration of a MH pump (MHP) equipped with a latent heat exchanger were investigated. The obtained results showed that using a PCM with MHP, as energy storage material, considerably enhances the performance of the pump. For example, with a heat transfer coefficient of 50 W/m2.K, an MH's thermal conductivity of 5.32 W/m. K, a PCM's thermal conductivity of 3 W/m. K, and pumping head of 25 m, it was noted that using Ba(OH)2‐8H2O with the pump as PCM decreases the pumping time by approximately 59% and allows for 17 times increase in overall efficiency over the case without PCM.

“…New renewable energy is urgently needed to address the issues of the energy crisis and environmental pollution. − Among the possibilities, hydrogen energy stands out because of the key advantages of high energy density and net calorific value of combustion, abundant resources, and zero pollution, to name a few. − Yet, its large-scale utilization is limited by the lack of efficient and safe storage processes. − A metal hydride is one of the high-profile materials for hydrogen storage due to its high volumetric hydrogen storage capacity and excellent safety performance, − and it mainly works in the forms of metal alloys or compounds. , Currently, metal hydrogen storage materials can be divided into three categories: (1) binary hydrides MH x (M = main-group or transition metal, such as LiH, MgH 2 , and AlH 3 ), − (2) intermetallic hydrides AB x H y (A and B represent the hydrogenated and unhydrogenated metals, respectively, such as Mg 2 NiH 4 and Mg 2 FeH 6 ), − and (3) complex metal hydrides, MEH x (e.g. LiNH 2 , [BH 4 ] − , and [AlH 6 ] − ). − Among the above metallic hydrogen storage materials, Mg-based hydrogen storage materials have attracted intense interest due to their high hydrogen storage capacity (7.6 wt %) and low cost. ,, Nevertheless, the sluggish hydrogenation and dehydrogenation kinetics, relatively stable thermodynamics, and high initial decomposition temperature remain major problems. − …”

Mg-based hydride materials (MgH2) are in the spotlight of hydrogen storage due to their high gravimetric density. Yet, its large-scale utilization is limited by the poor thermodynamic stability and slow kinetics. Herein, we report a novel and straightforward way to prepare MgH2 with amorphous carbon by cosintering 2-methylnaphthalene (CMN) organics with pure Mg and a hydriding combustion synthesis method, where the amorphous carbon formed from the CMN not only improves the dehydrogenation/hydrogenation capacity but also enhances the kinetics of the Mg/MgH2 system. The dehydrogenation capacity of the CMN-MgH2 composite reaches 4.88 wt % of H2 at 623 K, nearly 2 times of pure MgH2, and its onset dehydrogenation temperature decreases to 560 K, 90 K lower than that of pure MgH2; in addition, at a lower temperature of 473 K, the composite remarkably absorbs 4.54 wt % of H2 within 42 s while the absorption is only 0.71 wt % H2 for the pure MgH2. Moreover, the activation energy greatly decreases from 165.35 to 101.52 kJ/mol. Further research reveals that the evolution of hydrogenation changes from a three-dimensional diffusion process to a one-dimensional diffusion process, attributed to the formation of the amorphous carbon. This work is expected to provide inspiration to design and prepare effective additives for the improvement of hydrogen storage performance of Mg-based hydrides.
