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.
The hydride-forming alloys and intermetallic compounds are found to be the most important families of hydrogen storage materials. Multicomponent alloys consisting of five or more principal elements, also known as high-entropy alloys appear to have potential for the development as hydrogen storage materials.
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.
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.
High-energy-density hydrogen-storage technology is essential to bridge the gap between hydrogen production and its energy-storage applications. At the same time, hydrogen is a flammable and explosive gas: when the concentration of hydrogen in air is 4.1–75 vol% , it will explode in case of fire.
By harnessing the synergies between materials science, nanotechnology, and computational modeling, rare-earth-metal-based hydrogen storage materials are poised to accelerate the transition towards a sustainable hydrogen economy, ushering in a new era of clean energy solutions. 1. Introduction
