Abstract

This work consists of a systematic review showing recent progress and trends in the development of high entropy alloys (HEA) for solid-state hydrogen storage. The information was compiled from academic papers from the following databases: Google Scholar, ScienceDirect, Springer, SCOPUS, American Chemical Society, MDPI; as well as the patent banks United States Patent and Trademark Office, Google Patent and lens.org. This article discusses key aspects such as HEA design (elements used, thermodynamic and geometric characteristics, thermodynamic simulations and synthesis methods); HEA evaluation focusing on crystallinity, thermal behavior and hydrogen storage; HEA-related trends including MgH₂ modification, the advancement of lightweight alloys and the use of machine learning.
