“…Hydrogen is one of the most promising candidates as a future energy carrier owing to its high energy density, renewability, and environmental friendliness. , However, the hydrogen technology still suffers from major challenges of storage and transportation. , High-pressure storage in tanks, where hydrogen is compressed into a liquid form at low temperature, , hinders actual application of hydrogen energy due to the danger of gas compression and substantial cost to liquefy hydrogen. , To effectively use hydrogen as an energy carrier, safe hydrogen storage systems with high efficiency are necessary. For this reason, solid-state materials based on several light metals and alloys are of interest to store hydrogen in forms of chemical compounds, such as LiH, MgH 2 , NaH, LiBH 4 , and NaAlH 4 . ,, …”
