“…Compared with high cost cryogenic liquid storage and dangerous high compression gas tanks, hydrogen stored in solid-state materials shows easy manipulability temperature, low working pressure (Khafidz et al, 2016 ; Rusman and Dahari, 2016 ; Razavi et al, 2019 ). In the past decades, oceans of materials for hydrogen storage have been investigated, including physical adsorbents (carbon and MOF), complex hydrides (LiBH 4 , LiNH 4 , NaAlH 4 ), alloys hydrides (Mg 2 NiH 4 , TiFeH 2 , NaMgH 3 ), and metal hydrides (MgH 2 ) (Shao et al, 2015 ; Zhai et al, 2016 ; Xiao et al, 2017 ; Chen et al, 2019 ; Goto et al, 2019 ; He et al, 2019 , 2020 ; Liu H. et al, 2019 , 2020 ; Song et al, 2019 ; Jansa et al, 2020 ; Yao et al, 2020 ).…”

Magnesium hydride (MgH 2 ) has attracted intense attention worldwide as solid state hydrogen storage materials due to its advantages of high hydrogen capacity, good reversibility, and low cost. However, high thermodynamic stability and slow kinetics of MgH 2 has limited its practical application. We reviewed the recent development in improving the sorption kinetics of MgH 2 and discovered that transition metals and their alloys have been extensively researched to enhance the de/hydrogenation performance of MgH 2 . In addition, to maintain the cycling property during the de/hydrogenation process, carbon materials (graphene, carbon nanotubes, and other materials) have been proved to possess excellent effect. In this work, we introduce various categories of transition metals and their alloys to MgH 2 , focusing on their catalytic effect on improving the hydrogen de/absorption performance of MgH 2 . Besides, carbon materials together with transition metals and their alloys are also summarized in this study, which show better hydrogen storage performance. Finally, the existing problems and challenges of MgH 2 as practical hydrogen storage materials are analyzed and possible solutions are also proposed.

Hydrogen, which is a new clean energy option for future energy systems possesses pioneering characteristics making it a desirable carbon-free energy carrier. Hydrogen storage plays a crucial role in initiating a hydrogen economy. Due to its low density, the storage of hydrogen in the gaseous and liquids states had several technical and economic challenges. Despite these traditional approaches, magnesium hydride (MgH2), which has high gravimetric and volumetric hydrogen density, offers an excellent potential option for utilizing hydrogen in automobiles and other electrical systems. In contrast to its attractive properties, MgH2 should be mechanically and chemically treated to reduce its high activation energy and enhance its modest hydrogen sorption/desorption kinetics. The present study aims to investigate the influence of doping mechanically-treated Mg metal with 5 wt% amorphous Zr2Cu abrasive nanopowders in improving its kinetics and cyclability behaviors. For the first time, solid-waste Mg, Zr, and Cu metals were utilized for preparing MgH2 and amorphous Zr2Cu alloy (catalytic agent), using hydrogen gas-reactive ball milling, and arc melting techniques, respectively. This new nanocomposite system revealed high-capacity hydrogen storage (6.6 wt%) with superior kinetics and extraordinary long cycle-life-time (1100 h) at 250 °C.

The bulk Mg-M (M = Nickel [Ni], cerium [Ce], and Lanthanum [La]) alloys are successfully ameliorated by high-energy ball milling (HEBM) to modify the hydrolysis H 2 generation performance in simulated seawater solution (3.5 wt% NaCl). The H 2 generation kinetics, rate-limiting steps, thermodynamics and the hydrolysis mechanism are investigated by combining the fitting results of the hydrolysis curves and microstructures information. The results indicate that the as-cast Mg25Ni possesses higher generation capacity and faster initial rate. The capacities of as-cast Mg25Ni, Mg30Ce, and Mg30La alloys at 48 C within 180 minutes are 760 mL g −1 , 725 mL g −1 , and 525 mL g −1. The hydrolysis H 2 generation apparent activation energies of the as-cast Mg25Ni, Mg30Ce, and Mg30La alloys are 30.92, 17.05, and 28.04 kJÁmol −1 , respectively. The HEBM technique can elevate the hydrolysis performance of Mg-M alloys. And the highest H 2 producing capacity as high as 589 mL g −1 is obtained by HEBM Mg30La alloy at 48 C within 30 minutes. The hydrolysis apparent activation energies E a are 9.57, 14.65, and 23.88 kJ/mol for HEBM Mg25Ni, Mg30Ce, and Mg30La alloys. The initial rate and the final yield of H 2 generation for Mgbased alloys are affected by the activity of matrix alloy, microstructure, particle size, surface state, and many other factors.
