Abstract:

As a green energy carrier with wide sources, clean and zero carbon, hydrogen energy is an important way for China to achieve the long-term goals of carbon peak and carbon neutral. Due to its easy flammability, explosion and diffusion, one of the greatest challenges of hydrogen energy development is how to store hydrogen safely, efficiently and economically. As a new form of solid materials, storage of hydrogen in clathrate hydrates is carried out by capturing the hydrogen molecules into the three-dimensional cage structure (such as type Ⅰ, type Ⅱ, type H and semi-clathrate) formed by hydrogen-bonded water molecules with the help of different kinds of promoters. Considering the hydrogen storage density and hydrate formation stability, it is found that s‍Ⅱ hydrate promoters have the most promising potential. This paper first summarizes the influence of existing s‍Ⅱ hydrate promoters on the thermodynamic conditions of hydrogen hydrate formation, then compares the hydrogen storage capacity and the microscopic crystal structure changes of hydrogen hydrate in different promoter systems, and finally states the current development trend at home and abroad. It will provide theoretical guidance and technical support for the future industrial application of hydrogen hydrate storage.

Key words: hydrogen, hydrate, s?Ⅱ hydrate promoter, hydrogen storage capacity, phase equilibria

摘要:

氢能作为一种来源广泛、清洁、零碳的绿色能源载体,是我国实现碳达峰、碳中和愿景的重要抓手。由于氢易燃、易爆、易扩散,如何安全、高效、经济储氢是氢能发展的技术挑战之一。水合物固态储氢则是在不同种类促进剂作用下,通过水分子间氢键作用而形成的三维笼型结构(如Ⅰ型、Ⅱ型、H型以及半笼型)“捕获”氢气分子。综合考量储氢密度和水合物生成稳定性,发现sⅡ型水合物促进剂相对最具有应用潜力。本文首先归纳现有sⅡ型水合物促进剂对氢气水合物生成热力学条件的影响规律,然后比较分析了不同促进剂体系氢气水合物的储氢性能以及晶体微观结构的变化,最后总结国内外目前发展趋势,为水合物储氢的工业化应用提供理论依据和指导。
