- 摘要：氢能是助力中国实现“碳中和”、“碳达峰”的理想能源。氢的储运是“制储输用”氢能产业链中的瓶颈问题。金属氢化物储氢技术因其体积储氢密度高，且吸放氢过程可在常温低压条件下进行，降低了氢气泄漏和爆炸的风险而在近些年受到了广泛关注。金属氢化物的吸放氢过程会释放和吸收大量的热，温度的升高和下降会使吸放氢反应速率减慢，导致有效储氢量减少。换热性能是限制储氢性能的关键因素之一。详细论述了各种换热结构对储氢性能的影响以及不同换热结构的优点与劣势，有利于设计与优化高效、紧凑的换热结构，实现储氢反应器在运行过程中的快响应和低能耗，为金属氢化物储氢技术的规模化应用奠定基础。Abstract: Hydrogen energy is an ideal energy source for achieving "carbon neutrality" and "peak carbon emissions" in ourcountry. The storage and transportation of hydrogen represent a bottleneck in the "production, storage, transportation, andutilization" of the hydrogen energy industry chain. Metal hydride hydrogen storage technology has gained widespread attention inrecent years due to its high volumetric hydrogen density and the ability to perform hydrogen absorption and release at roomtemperature and low pressure, reducing the risk of hydrogen leakage and explosion. The absorption and desorption processes ofmetal hydrides involve the release and absorption of a significant amount of heat, with temperature fluctuations slowing thereaction rates and leading to a decrease in effective hydrogen storage. Heat transfer performance is one of the key factors limitinghydrogen storage capabilities. A detailed discussion of the impact of various heat exchange structures on hydrogen storageperformance, as well as their respective advantages and disadvantages, facilitates the design and optimization of efficient andcompact heat exchange structures, enabling rapid response and low energy consumption during the operation of hydrogen storagereactors. This lays the foundation for the large-scale application of metal hydride hydrogen storage technology.
