“…MgH 2 , a lightweight binary metal hydride, has been widely investigated as one of the most promising solid hydrogen storage materials due to its low cost, abundant resources, high hydrogen storage capacity and good reversibility. The reversible hydrogen storage capacity of Mg/MgH 2 can reach approximately 7.6 wt.%, which satisfies DOE’s regulations [ 1 , 5 , 6 , 34 ]. However, the hydrogen storage performance of Mg/MgH 2 has certain drawbacks, such as high thermodynamic stability (enthalpy ~76 kJ/mol and entropy ~130 kJ/mol [ 35 ]), slow hydrogen absorption/desorption kinetics and high temperature of hydrogen absorption/desorption, which are the main reasons why Mg/MgH 2 is difficult to be used on a large scale.…”

“…In the past, scholars have studied a variety of solid-state hydrogen storage materials, including physisorption materials, such as carbon-based materials, metal organic framework (MOFs) and zeolites, as well as chemisorption materials, such as hydrogen storage alloys, complex metal hydrides and lightweight binary metal hydrides. The U.S. Department of Energy (DOE) specifies that the on-board hydrogen storage system should have a hydrogen storage capacity of 5.5 wt.% at a hydrogen pressure of 5–12 bar and a temperature of about 85 °C, and the number of cycles of hydrogen storage materials should not be less than 1000 [ 5 , 6 ]. Figure 1 shows not only the different hydrogen storage technologies and their hydrogen storage capacities but also DOE’s goals for hydrogen storage systems for comparison [ 7 ].…”

Due to its high hydrogen storage efficiency and safety, Mg/MgH2 stands out from many solid hydrogen storage materials and is considered as one of the most promising solid hydrogen storage materials. However, thermodynamic/kinetic deficiencies of the performance of Mg/MgH2 limit its practical applications for which a series of improvements have been carried out by scholars. This paper summarizes, analyzes and organizes the current research status of the hydrogen storage performance of Mg/MgH2 and its improvement measures, discusses in detail the hot studies on improving the hydrogen storage performance of Mg/MgH2 (improvement measures, such as alloying treatment, nano-treatment and catalyst doping), and focuses on the discussion and in-depth analysis of the catalytic effects and mechanisms of various metal-based catalysts on the kinetic and cyclic performance of Mg/MgH2. Finally, the challenges and opportunities faced by Mg/MgH2 are discussed, and strategies to improve its hydrogen storage performance are proposed to provide ideas and help for the next research in Mg/MgH2 and the whole field of hydrogen storage.

“…The pressure used is normally between 1.0 and 10 MPa, but this varies based on the adsorbent and planned usage. Higher pressures are not advantageous due to the volume occupied by the adsorbent 59 . The most prominent adsorbents are 58 : Porous carbon‐based materials; Metallo‐organic structures; Porous polymeric materials; Zeolites. …”

In the current world energy scenario with rising prices and climate emergencies, the renewable energy sources are essential for reducing pollution levels triggered by carbon‐based fuels. Hydrogen rises in the world energy scenario as an important non‐carbon‐based energy able to replace fossil fuels. For this reason, the rapid development of hydrogen‐related technology has been seen in recent years. This review paper covers hydrogen energy systems from fossil fuel‐based hydrogen production, biomass and power from renewable energy sources, to hydrogen storage in compressed gases, liquefied and solid materials, and hydrogen‐based power generation technology. It represents a quiet complete set of references that may be effective in increasing the prospects of hydrogen as a fuel in the coming years. The main conclusions drawn are that natural gas and coal supply nearly all of the current hydrogen. The commercially available technologies for hydrogen production are steam methane reforming, partial oxidation, and alkaline electrolysis. The most economical methods for hydrogen production are partial oxidation, steam methane reforming, coal gasification, and biomass gasification. Metallic cylindrical reservoirs are the most promising alternative to underground storage of compressed hydrogen at large scales. Some metal compounds and composites can store a significant amount of hydrogen while maintaining reasonable adsorption and desorption kinetics. The transportation sector is likely to see widespread use of hydrogen in the future, helping to reduce pollution. Vehicles can be powered by fuel cells, which are much more efficient than internal combustion engines. There are still several obstacles in the way of widespread hydrogen utilization. The first one is that the cost of producing hydrogen from low‐carbon sources is elevated. As the cost of renewable energy declines and hydrogen production is scaled up, it is anticipated that the hydrogen production costs would decrease over the next years. Innovative technologies are expected to increase the interest on thermochemical hydrogen production to massively substitute electrochemical technologies since they are theoretically cost‐effective. More research is needed to fix concerns with some of the thermochemical cycles in order to rise its maturity. Increasing the chemical reaction conversion ratios, which can be resolved utilizing nonequilibrium reactions, is one of them. The transportation sector is likely to see extensive use of hydrogen in the future, helping to reduce carbon dioxide emissions. The power required by vehicles may be supplied by fuel cells, which are more efficient than internal combustion engines.

“…Hydrides were chosen for storage applications due to low reactivity and the ability of storing high densities of hydrogen which it can be achieved in two main ways: heating (thermolysis) or reaction with water (hydrolysis). Thermolysis is endothermic and reversible in some cases while hydrolysis is exothermic and irreversible; thermolysis occurs in the solid phase with elevated temperatures while hydrolysis occurs in solution at normal room temperature [12]. Releasing the stored hydrogen requires high temperature between 120-200 o C to break the bonds that the metal hydrides is forming with hydrogen [13].…”

Hydrogen can provide a viable source of energy that can covers the world’s energy requirement in the next coming years. One of the major keys to wholly develop hydrogen energy is to provide a safe, cost efficient and compacted type of hydrogen storage. Geological reserves are considered a suitable space for hydrogen storage. In this research, we are trying to examine if there was any technical potential for hydrogen storage based on Oman’s geology by Identifying geological deposit in Oman that can be used for hydrogen storage and analyzing salt deposits for hydrogen storage suitability. By overviewing the possible underground hydrogen methods and based on Oman’s geology, deep aquifers were not suitable for hydrogen storage; due to the lack of large sedimentary basin, no experience for similar projects and the risks associated with surrounding environment. Depleted reservoir needs more study for deployment; there are no experiences of such projects for UHS. Salt basins are good candidate for underground storage; due to the large salt basin in Oman, salt caverns are known to successfully contain hydrogen and the guaranteed safety of the storage. Analysing the technical potential salt deposits was based on a good depth dome, salt thickness and salt dome size. The main findings illustrate that, two salt domes (Qarn Shamah and Qarn Alam) were offering a good potential of estimated working gas volume of hydrogen around 90 m3 hydrogen (0.2 TWh). Nevertheless, more future work is needed to confirm the geotechnical feasibility of salt domes in terms of internal complex structure, chemical composition and purity of salt.
