The hydrogen economy is the key solution to secure a long-term energy future. Hydrogen production, storage, transportation, and its usage completes the unit of an economic system. These areas have been the topics of discussion for the past few decades. However, its storage methods have conflicted for on-board hydrogen applications. In this review, the promising systems based on solid-state hydrogen storage are discussed. It works generally on the principles of chemisorption and physisorption. The usage of hydrogen packing material in the system enhances volumetric and gravimetric densities of the system and helps in improving ambient conditions and system kinetics. Numerous aspects like pore size, surface area ligand functionalization and pore volume of the materials are intensively discussed. This review also examines the newly developed research based on MOF (Metal-Organic Frameworks). These hybrid clusters are employed for nano-confinement of hydrogen at elevated temperatures. A combination of the various methodologies may give another course to a wide scope in the area of energy storage materials later in the future.
氢能经济是确保长期能源未来的关键解决方案。氢气的生产、储存、运输及其用途构成了一个经济系统单元。在过去几十年里，这些领域一直是讨论的话题。然而，其储存方法在车载氢应用方面存在冲突。在这篇综述中，讨论了基于固态储氢的有前景的系统。它通常基于化学吸附和物理吸附原理工作。系统中氢填充材料的使用提高了系统的体积密度和重量密度，并有助于改善环境条件和系统动力学。对材料的孔径、表面积配体功能化和孔体积等诸多方面进行了深入讨论。本综述还考察了基于金属有机框架（MOF）的新开展的研究。这些混合簇用于在高温下对氢进行纳米限域。各种方法的结合可能会在未来为储能材料领域带来更广阔的发展方向。
