This manuscript contributes to understanding the role of hydrogen in different materials, emphasizing polymers and composite materials, to increase hydrogen storage capacity in those materials. Hydrogen storage is critical in advancing and optimizing sustainable energy solutions that are essential for improving their performance. Capillary arrays, which offer increased surface area and optimized storage geometries, present a promising avenue for enhancing hydrogen uptake. This work evaluates various polymers and glass for their mechanical properties and strength with 700 bar inner pressure loads within capillary tubes. A theoretical mathematical approach was employed to quantify the impact of material properties on storage capacity. Our results demonstrate that certain polymers (e.g., Zylon AS, Dyneema SK99) and glass types (S-2 Glass) exhibit superior hydrogen storage potential due to their enhanced strength and low density. These findings suggest that integrating the proposed materials into capillary array systems can significantly improve hydrogen storage efficiency (15-37 wt.% and 37-40 g/L), making them viable candidates for next-generation energy storage systems. This study provides valuable insights into material selection and structural design strategies for high-capacity hydrogen storage technologies.
本手稿有助于理解氢在不同材料（重点是聚合物和复合材料）中的作用，以提高这些材料的储氢能力。储氢对于推进和优化可持续能源解决方案至关重要，而这些解决方案对于提高其性能必不可少。提供更大表面积和优化存储几何形状的毛细管阵列，为增强氢吸收提供了一条有前景的途径。这项工作评估了各种聚合物和玻璃在毛细管内700巴内压负载下的机械性能和强度。采用了一种理论数学方法来量化材料性能对存储容量的影响。我们的结果表明，某些聚合物（如Zylon AS、Dyneema SK99）和玻璃类型（S-2玻璃）由于其增强的强度和低密度而表现出卓越的储氢潜力。这些发现表明，将所提出的材料集成到毛细管阵列系统中可以显著提高储氢效率（15 - 37重量%和37 - 40克/升），使其成为下一代储能系统的可行候选材料。本研究为高容量储氢技术的材料选择和结构设计策略提供了有价值的见解。
