Among them, alloys have become leading hydrogen-storage materials owing to their favorable cost, safety, operating conditions, particularly their high energy density by volume. For example, the most commonly used commercial hydrogen-storage alloy in nickel–metal hydride batteries is the AB 5 alloy with a CaCu 5 crystal structure.
In recent years, high-entropy alloys (HEAs) have been extensively applied to structural and functional materials owing to their unique physical and chemical properties. Therefore, HEAs have emerged as a promising materials. This review summarizes recent research progress on HEAs for hydrogen storage.
For example, the most commonly used commercial hydrogen-storage alloy in nickel–metal hydride batteries is the AB 5 alloy with a CaCu 5 crystal structure. However, conventional alloys also face many problems in hydrogen storage.

Other materials, such as metal hydrides, complex hydrides, and lightweight alloys, also show potential for solid-state hydrogen storage. For instance, magnesium-based alloys are known for their high hydrogen storage capacity but require optimization for better kinetics and lower operational temperatures.
The results of this study indicate that HEAs are potential hydrogen-storage materials; however, additional research and improvements are required to enhance their hydrogen storage/release rate and cycle stability. HEAs are anticipated to become increasingly important in hydrogen energy storage and transportation in the future.
