Hydrogen is a pure, high-energy fuel that is readily available worldwide. However, its economic system, which depends on hydrogen, is confronted with difficulties in manufacturing, storage, and application, rendering it a difficult option. Extensive research has been conducted on chemical hydrogen storage materials, which are chemically bound to other elements. The initial research concentrated on metal alloys, which have a low gravimetric hydrogen density of typically less than 2 wt% but absorb hydrogen swiftly. MgH2 extensive application is hindered by its poor cycle performance, sluggish hydrogen sorption kinetics, and high thermal stability, despite its numerous benefits. Hydrogen is an alternate source of energy that can be utilized either directly or indirectly. Storage hydrogen, thereby providing a more flexible deployment and increased energy density developments facilitate the transformation of surplus renewable energy through. Additionally, investigation is required to facilitate interaction. This investigation employs the ball milling method to generate a nanocomposite composed of Mg + 5 wt % (Ti3C2F + Cr). 2.52 wt% of hydrogen can be stored in the nano-composite Mg + 5 wt% (MX + Cr) at a temperature of 320 °C. Thermal behavior and desorption reactions induced by additives are demonstrated by the 11.4 wt% total weight loss. To characterize samples, XRD was implemented. The dehydrating reaction has an activation energy of 168.77 kJ/mol.
