Hydrogen energy is a very attractive option in dealing with the existing energy crisis. For the development of a hydrogen energy economy, hydrogen storage technology must be improved to over the storage limitations. Compared with traditional hydrogen storage technology, the prospect of hydrogen storage materials is broader. Among all types of hydrogen storage materials, solid hydrogen storage materials are most promising and have the most safety security. Solid hydrogen storage materials include high surface area physical adsorption materials and interstitial and non-interstitial hydrides. Among them, interstitial hydrides, also called intermetallic hydrides, are hydrides formed by transition metals or their alloys. The main alloy types are A2B, AB, AB2, AB3, A2B7, AB5, and BCC. A is a hydride that easily forms metal (such as Ti, V, Zr, and Y), while B is a non-hydride forming metal (such as Cr, Mn, and Fe). The development of intermetallic compounds as hydrogen storage materials is very attractive because their volumetric capacity is much higher (80–160 kgH2m−3) than the gaseous storage method and the liquid storage method in a cryogenic tank (40 and 71 kgH2m−3). Additionally, for hydrogen absorption and desorption reactions, the environmental requirements are lower than that of physical adsorption materials (ultra-low temperature) and the simplicity of the procedure is higher than that of non-interstitial hydrogen storage materials (multiple steps and a complex catalyst). In addition, there are abundant raw materials and diverse ingredients. For the synthesis and optimization of intermetallic compounds, in addition to traditional melting methods, mechanical alloying is a very important synthesis method, which has a unique synthesis mechanism and advantages. This review focuses on the application of mechanical alloying methods in the field of solid hydrogen storage materials.

“…Hydrogen, as a secondary energy carrier, plays a crucial role in mitigating future energy shortages and environmental pollution challenges. It offers the advantages of high energy density, abundant reserves, environmental friendliness, and renewable potential. , The storage methods for hydrogen primarily consist of liquid storage (liquefied hydrogen), gaseous storage (compressed hydrogen), and solid-state storage (hydrogen storage materials) . Liquid hydrogen storage necessitates the liquefaction of hydrogen gas at extremely low temperatures (21.2 K), which consumes a significant amount of energy.…”

Striking a balance between hydrogen storage properties and cost is a challenge for Ti−Mn alloys. In this work, a strategy involving the utilization of inexpensive Ti to occupy Mn sites is employed to enhance the hydrogen storage properties of Ti−Mn alloys. The relationship between the composition, phases, electronic structure, and hydrogen storage properties of Ti 1+x Mn 2−x (x = 0.20, 0.25, 0.30, 0.35, 0.40, and 0.45) alloys is investigated systematically. The experiments demonstrate that the substitution ratio x of Ti occupying Mn sites is between 0.25 and 0.3. Once exceeded, the alloys gradually precipitate the αTiMn and βTi phases. All of the alloys do not require high-temperature activation. The Ti 1.25 Mn 1.75 alloy exhibits the highest reversible hydrogen storage capacity of 1.94 wt % under 25 °C and 6 MPa. The first-principles calculation reveals that the partial substitution of Ti for Mn changes the electronic structure of the alloy and lowers the solid solution energy of H atoms within the interstitial sites of the alloy. This accounts for the observed decrease in the alloy plateau pressure following the partial substitution of Ti for Mn. This research provides valuable insights into the design of high-performance Ti−Mn hydrogen storage alloys using inexpensive elements.

“…Notably, storing gaseous hydrogen at high pressure (350~700 bar) in storage tanks and transporting it via tube trailers is a prominent approach, as is liquefying gaseous hydrogen (−253 ℃) and storing it in dedicated storage tanks. These methods require specialized infrastructure due to the high energy density of hydrogen, and liquefaction, in particular, incurs significant energy consumption [46][47][48][49][50][51][52][53][54][55][56][57][58][59]. As alternatives, research is underway on physically adsorbing hydrogen onto porous materials such as Metal Organic Frameworks (MOFs) and Carbon nanotubes for storage and transportation, as well as chemically binding hydrogen to metals to enable solid-state storage and desorption, as seen in metal hydrides.…”

In light of climate change imperatives, there arises a critical need for technological advancements and research endeavors towards clean energy alternatives to replace conventional fossil fuels. Additionally, the development of high-capacity energy storage solutions for global transportability becomes paramount. Hydrogen emerges as a promising environmentally sustainable energy carrier, devoid of carbon dioxide emissions and possessing a high energy density per unit mass. Its versatile applicability spans various sectors including industry, power generation, and transportation. However, the commercialization of hydrogen necessitates further technological innovations. Notably, high-pressure compression for hydrogen storage presents safety challenges and inherent limitations in storage capacity about 30%–50% lost production of hydrogen. Consequently, substantial research endeavors are underway in the domain of material-based chemical hydrogen storage that reactions to occur at temperatures below 200 ℃. This approach enables the utilization of existing infrastructure, such as fossil fuels and natural gas, while offering comparatively elevated hydrogen storage capacities. This study aims to introduce recent investigations concerning the synthesis and decomposition mechanisms of chemical hydrogen storage materials, including methanol, ammonia, and Liquid Organic Hydrogen Carrier (LOHC).
