Abstract: Hydrogen is increasingly being recognized as a clean energy carrier that is vital for decarbonizing industries and integrating renewable energy sources. Efficient hydrogen storage is critical for its widespread adoption and economic viability. Among promising solutions, zeolites have gained attention because of their unique microporous structures, high surface areas, and modifiable chemical properties. These characteristics enable zeolites to effectively adsorb hydrogen molecules, making them suitable for sustainable energy storage and transportation. The exceptional physicochemical properties of zeolites, such as ion exchange and adsorption capacities, allow tailored modifications to enhance their hydrogen storage performance. Techniques such as surface functionalization with amines and ion exchange with specific cations significantly improve adsorption capacity and efficiency. For instance, amine modifications introduce electrostatic interactions, whereas ion exchange optimizes the pore structure and increases the surface charge. Recent studies have highlighted the potential of silver ion-exchanged zeolites for selective hydrogen isotope separation, demonstrating the versatility of these materials. With advancements in zeolite research, the development of scalable, cost-effective, and high-capacity hydrogen storage systems has become increasingly feasible. These innovations position zeolites as key contributors to clean energy transition, supporting the role of hydrogen as a cornerstone of sustainable energy infrastructure.
