Hydrogen is the energy carrier with the highest energy density and is critical to the development of renewable energy. Efficient hydrogen storage is essential to realize the transition to renewable energy sources. Electrochemical hydrogen storage technology has a promising application due to its mild hydrogen storage conditions. However, research on the most efficient electrochemical hydrogen storage materials that satisfy the goals of the U.S. Department of Energy remain open questions. All of the above require strategies for designing new hydrogen storage materials. This review provides a brief overview of hydrogen preparation, hydrogen storage, and details the development of electrochemical hydrogen storage materials. We summarize the electrochemical hydrogen storage capabilities of alloys and metal compounds, carbonaceous materials, metal oxides, mixed metal oxides, metal−organic frameworks, MXenes, and polymer-based materials. It was observed that mixed metal oxides exhibit superior discharge capacity and cycling stability. The review indicates that it is vital to create novel materials with large surface area, active-conductive profiles, and low cost. We describe the challenges, gaps, and future perspectives of electrochemical hydrogen storage materials, and hope that the review could draw more attention to the development of electrochemical hydrogen storage materials with high hydrogen storage capacity, high safety, high cycle stability, and low cost and promoting their practical applications.

“…Possible bulk hydrides formation using high pressure hydrogenation system In this current account ZrZn2 and ZrAl2 Laves phases exhibit very attractive and interesting physicochemical properties, as an insight of appropriate matrix substitution (considering suitable metal substitute ZrB2-xMx, B = Zn or Al, and M = Cobalt, Copper or/and Manganese) is particularly contributing in emerging advanced reversible HSA hydrogen storage nano-materials (Figure 3). We are involved in our laboratory framework in developing new Zirconium based AB3 alloys like CeZr2Ni5Cr4 and LaZr2Ni5Cr4 having interesting hydrogenation properties particularly the electrochemical storage in Nickel-Metal Hydride Batteries Ni-MH (Sahli et al, 2017(Sahli et al, , 2016. We are also seeking recently to substitute and replace toxic Chromium using other more sustainable elements (Jaafar et al, 2020(Jaafar et al, , 2018Slama et al, 2019).…”

The present concise communication emphasizes on two zirconium based AB2 alloys (ZrZn2 and ZrAl2) with an overview concerning the basic physicochemical properties alongside their structure, elastic, or magnetic nature, with further outlook in hydrogenation application purpose. We started introducing the general aspects of using Zirconium based intermetallics with their advantages and the prevalent apprehension about binary phase diagram of Al-Zr and Zn-Zr systems. We outlined extensive examples overlapping these different properties and we highlighted the importance of hydrogen storage materials in the current worldwide concern about using clean energy.

A novel alloy LaTi 2 Ni 5 Al 4 is investigated in this work. This quaternary composite belongs to the new generation of AB 3 intermetallics elaborated using the mechano-milling method. Several analytical techniques are operated in order to verify and confirm the crystallographic patterns following the growth progression of this nanoalloy. Starting from elemental metals, the authors show that they have basically LaTi 2 Ni 5 Al 4 major pattern corresponding to the symmetry crystal system (Trigonal R-3 m SG: 166). Structure refinement simulation demonstrates that performing this preparation with a laboratory grinding and milling benchtop, they obtain a maximum proportion of AB 3 intermetallic alloy after 20 h of metallurgy work processing. The proposition of useful stabilised solid-hydrogen encapsulation is highlighted and tested using a specific lithium-hydride cell.
