Research Progress on Heat Exchange Structure of Metal Hydride Hydrogen Storage Reactor
Hydrogen energy is an ideal energy source for achieving"carbon neutrality"and"peak carbon emissions"in our country.The storage and transportation of hydrogen represent a bottleneck in the"production,storage,transportation,and utilization"of the hydrogen energy industry chain.Metal hydride hydrogen storage technology has gained widespread attention in recent years due to its high volumetric hydrogen density and the ability to perform hydrogen absorption and release at room temperature and low pressure,reducing the risk of hydrogen leakage and explosion.The absorption and desorption processes of metal hydrides involve the release and absorption of a significant amount of heat,with temperature fluctuations slowing the reaction rates and leading to a decrease in effective hydrogen storage.Heat transfer performance is one of the key factors limiting hydrogen storage capabilities.A detailed discussion of the impact of various heat exchange structures on hydrogen storage performance,as well as their respective advantages and disadvantages,facilitates the design and optimization of efficient and compact heat exchange structures,enabling rapid response and low energy consumption during the operation of hydrogen storage reactors.This lays the foundation for the large-scale application of metal hydride hydrogen storage technology.
