“…Fossil fuels are currently employed as the primary source of energy, given that they are considered necessary for energy production and distribution. However, this has resulted in a severe energy crisis and global deterioration of the environment . Thus, according to estimates, the combustion of fossil fuels results in the rapid annual emission of around 40 million tons of greenhouse gases and hazardous chemicals.…”

The stabilities, electronic properties, and reactivities of hydrogen interactions with Cu-, Ag-, and Au-decorated aluminum nanotubes (AlNNT), H 2 -AlNNT, H 2 -Ag@AlNNT, H 2 -Au@AlNN T, and H 2 -Cu@AlNNT, for efficient hydrogen storage were investigated using density functional theory (DFT) computations at the ωB97XD/def2svp level of theory. The electron shared by H 2 -Ag@AlNNT, H 2 -Au@AlNNT, and H 2 -Cu@AlNNT, as well as the chemical bond created with the adsorbed hydrogen molecule, indicate chemisorption from the electron localization function (ELF) analysis, which is compatible with the adsorption energies obtained. H 2 -Cu@AlNNT exhibited molecular physisorption with an average hydrogen adsorption energy (E ads ) of −0.027 eV, whereas H 2 -AlNNT, H 2 -Ag@AlNNT, and H 2 -Au@AlNNT exhibited chemisorption behavior. The molecular adsorption energies for H 2 -Ag@AlNNT and H 2 -Au@AlNNT were, respectively, −0.136 and −0.081 eV. Thus, in comparison to the other H 2 -adsorbed systems under investigation, the highest obtained adsorption energies were observed for these two decorated nanotube systems, respectively. H 2 -Ag@AlNNT and H 2 -Au@AlNNT are, therefore, better when compared to the other studied materials in terms of storage and adsorption of hydrogen molecules. Additionally, the negative value of E ads shows that the stated hydrogen molecule's adsorption is thermodynamically efficient. Also, in comparison with the Department of Energy (DOE) standard, the calculated wt % values for the studied systems were found to be 6.0 and 5.8 wt % for the AlNNT and metal-decorated systems, respectively. This is quite lower than the recommended standard; however, adsorption of more hydrogen molecules and surface engineering could improve the obtained wt %. The desorption temperature was also found to be within the required range for storage materials, according to DOE. Ab initio molecular dynamics simulation also confirms surface stability. Correspondingly, the NCI analysis reveals that the nature of the connection is linked to van der Waals forces and that the hydrogen molecule interacts well with the adsorbent surfaces. These phenomenal results enshrined probably the noble metal-decorated AlN nanotube materials as efficient reservoir materials for hydrogen storage.

“…Hydrogen can be physically stored as a compressed gas in a storage tank under high pressure for transportation. However, the main concern with hydrogen storage is the leakage of compressed gas (Li et al 2022b), as experiencing a high-pressure hydrogen leak can result in an explosion, leading to significant injuries and property damage. Accordingly, a previous study (Nasser et al 2022a) established that the storage system raises hydrogen production costs due to the increased capital cost of system components.…”

Hydrogen energy, as clean and efficient energy, is considered significant support for the construction of a sustainable society in the face of global climate change and the looming energy revolution. Hydrogen is one of the most important chemical substances on earth and can be obtained through various techniques using renewable and nonrenewable energy sources. However, the necessity for a gradual transition to renewable energy sources significantly hampers efforts to identify and implement green hydrogen production paths. Therefore, this paper’s objective is to provide a technological review of the systems of hydrogen production from solar and wind energy utilizing several types of water electrolyzers. The current paper starts with a short brief about the different production techniques. A detailed comparison between water electrolyzer types and a complete illustration of hydrogen production techniques using solar and wind are presented with examples, after which an economic assessment of green hydrogen production by comparing the costs of the discussed renewable sources with other production methods. Finally, the challenges that face the mentioned production methods are illuminated in the current review.

“…Among these three hydrogen storage technologies, solid-state hydrogen storage is the most promising hydrogen storage technology due to its good safety and high volumetric hydrogen storage density. 3,[5][6][7] In order to develop the solid-state hydrogen storage technology, we must nd and develop different high-performance hydrogen storage materials. TiFe alloy has attracted much attention because of its excellent properties including high hydrogen storage capacity (around 1.86 wt%), low cost and abundant reserves.…”
