Abstract:

As a type of environmentally friendly and renewable energy, hydrogen energy has gradually matured its production technology, and its cost has dropped significantly. It will usher in a period of opportunity for rapid development. The key to the widespread utilization of hydrogen energy is whether it can achieve efficient storage. This article focuses on four new types of hydrogen storage materials, metal complex hydride hydrogen storage materials, carbon nanotube hydrogen storage materials, zeolites, new types of zeolite materials, and organic liquid hydrogen storage materials. Metal complex hydride hydrogen storage materials has low storage pressure but poor cycle stability. Carbon nanotube hydrogen storage materials has a long history of development with high safety and easy dehydrogenation, but the current understanding of their hydrogen storage mechanism is not mature enough. Zeolite and new zeolite materials is cheap, but they have high requirements for reaction conditions. Organic liquid hydrogen storage materials is considered to be a viable option for large-scale storage and transportation, but their high cost and harsh reaction conditions limit their development. In the future, it is necessary to improve and develop hydrogen storage materials with higher storage capacity and economic value.

Key words: hydrogen energy, metal complexed hydride, carbon nanotube, zeolite and new zeolite materials, organic liquid hydrogen storage materials

摘要：

氢能作为一种环保可再生的新型能源，生产技术逐渐走向成熟，成本大幅度下降，将迎来快速发展的机遇期。氢能被广泛利用的关键在于是否能够实现高效储存。本文重点讨论了四类新型储氢材料，即金属络合氢化物储氢材料、碳纳米管储氢材料、沸石以及新型沸石类材料、有机液态储氢材料。文章指出：金属络合氢化物储氢材料储存压力低但循环稳定性差；碳纳米管储氢材料已经有很长的发展历史，安全性高且易脱氢，然而目前对其储氢机理认识不够成熟；沸石以及新型沸石类材料价格低廉，但是对反应条件的要求高；有机液态储氢材料被认为是大规模储存和运输的可行选择，然而昂贵的成本和苛刻的反应条件限制了其发展。文章指出后续需要改进并开发具有较高存储容量和具有经济价值的储氢材料。
