A study by Juahir et al. [11] investigated the effect of Co 2 NiO nanoparticle catalysts on the hydrogen storage properties of magnesium alloys. The results showed that the addition of Co 2 NiO catalysts significantly improved the hydrogen absorption and desorption kinetics of the magnesium alloys, and also decreased their desorption activation energy from
Of potential hydrogen storage materials, pure magnesium would be best from the standpoint of hydrogen capacity per unit mass. However, pure magnesium has poor hydriding kinetics. Alloying magnesium with nickel and other transition metals aids catalysis of the hydrogen dissociative chemisorption and yields other benefits by lowering the dehydrogenation temperature,
For example, the most commonly used commercial hydrogen-storage alloy in nickel–metal hydride batteries is the AB 5 alloy with a CaCu 5 crystal structure. However, conventional alloys also face many problems in hydrogen storage. Each alloy has its own advantages and disadvantages, and their overall performance is still far from the targets of

Nickel-iron alloys are characterized by relatively high permeability and low core losses. Their overall high saturation flux density means high performance energy storage and transfer over low to middle frequencies. Key Markets & Applications
In order to mitigate climate change and transition to a low-carbon economy, such ambitious targets highlight the urgency of collective action. To meet these gaps and maintain a balance between electricity production and demand, energy storage systems (ESSs) are considered to be the most practical and efficient solutions.

Based on the condition of the energy storage material, Socaciu's review divides SHS generally into two categories: sensible liquid storage and sensible solid storage (Fig. 11). While sensible liquid storage makes use of liquids like water or molten salts, sensible solid storage makes use of materials like rocks or soil.
For iron-base alloys and, thus, much higher Fe contents, the Ni content on the other hand now appears to be too low, as AT and A3 exhibit higher overpotentials of 332±1 and 336±1 mV respectively.
To meet these gaps and maintain a balance between electricity production and demand, energy storage systems (ESSs) are considered to be the most practical and efficient solutions. ESSs are designed to convert and store electrical energy from various sales and recovery needs [, , ].
