Generating sustainable energy is now a top priority to ensure the long-term sustainability of mankind. In order to address the upcoming global energy needs, it is crucial to focus on generating efficient, renewable energy sources such as hydrogen (H2). Around the world, researchers have been searching for promising materials to store hydrogen. At present, hydrogen is utilized in either compressed gas form in high-pressure tanks or as a liquid in tanks. Nevertheless, these storage methods present safety concerns, which is why the solid-state storage approach is an appealing alternative. Within this framework, the promise of lightweight, advanced solid-state materials such as MXenes enables reversible hydrogen storage. The remarkable qualities of MXenes, such as their higher surface area, customizable interlayer spacing, and thermal stability, make them more effective 2D layered materials for storing hydrogen. Recently, a few 2D multilayer Ti3C2Tx MXenes have shown an H2 storage capacity of 10.47 wt% unveiling an impressive hydrogen absorption in the MXene sample. The hydrogen storage capabilities of MXenes are significantly influenced by their chemistry. This chapter thoroughly examines the potential of MXenes for hydrogen storage applications, addressing both challenges and future prospects.
