Hydrogen (H) is one of the best candidates to replace current petroleum energy resources due to its rich abundance and clean combustion. However, the storage of H presents a major challenge. There are two methods for storing H fuel, chemical and physical, both of which have some advantages and disadvantages. In physical storage, highly porous organic polymers are of particular interest, since they are low cost, easy to scale up, metal-free, and environmentally friendly. In this review, highly porous polymers for H fuel storage are examined from five perspectives: (a) brief comparison of H storage in highly porous polymers and other storage media; (b) theoretical considerations of the physical storage of H molecules in porous polymers; (c) H storage in different classes of highly porous organic polymers; (d) characterization of microporosity in these polymers; and (e) future developments for highly porous organic polymers for H fuel storage. These topics will provide an introductory overview of highly porous organic polymers in H fuel storage.
氢（H）因其丰富的储量和清洁的燃烧特性，是替代当前石油能源的最佳候选者之一。然而，氢的储存面临着重大挑战。储存氢燃料有化学和物理两种方法，这两种方法都有各自的优缺点。在物理储存中，高度多孔的有机聚合物特别受关注，因为它们成本低、易于扩大规模、不含金属且环保。在这篇综述中，从五个方面对用于氢燃料储存的高度多孔聚合物进行了研究：（a）高度多孔聚合物与其他储存介质中氢储存的简要比较；（b）氢分子在多孔聚合物中物理储存的理论考量；（c）不同类型高度多孔有机聚合物中的氢储存；（d）这些聚合物中微孔的表征；以及（e）用于氢燃料储存的高度多孔有机聚合物的未来发展。这些主题将提供关于高度多孔有机聚合物在氢燃料储存方面的入门概述。
