Research Progress of Metal Hydrogen Storage Materials
Hydrogen energy is a renewable and clean energy source widely used in industries,transportation,electricity,and construction.With the increase of social demand,the consumption of hydrogen energy has been increasing year by year,however,the density of hydrogen is relatively low,making large-scale transportation and storage difficult,therefore,the performance of hydrogen storage materials determines whether hydrogen energy can be applied on a large scale.At present,hydrogen storage methods mainly include low-temperature liquid hydrogen storage,high-temperature gaseous hydrogen storage,and solid-state hydrogen storage,and metal hydrogen storage materials can be divided into magnesium series,vanadium series,rare earth series,titanium series,zirconium series,and calcium series.Based on the mature and promising hydrogen storage methods,the research status of metal hydrogen storage materials is reviewed,and the development direction of metal hydrogen storage materials is looked forward,in order to further improve the hydrogen storage performance of metal hydrides and alloys.
