Hydrogen storage holds significant promise for enabling a clean and sustainable energy future. However, the widespread adoption of hydrogen storage technologies is hindered by material selection and durability challenges, particularly due to hydrogen embrittlement. This paper comprehensively reviews the effects of hydrogen embrittlement on materials utilized for hydrogen storage applications. By examining relevant literature, we explore the mechanisms underlying hydrogen embrittlement and its impact on the mechanical properties of materials commonly used for hydrogen storage, including metals, alloys, and polymers. Furthermore, strategies for mitigating hydrogen embrittlement effects, such as material modification, coating techniques, and operational considerations, are discussed. By elucidating the complexities of hydrogen embrittlement and offering insights into potential mitigation strategies, this review aims to advance materials science for hydrogen storage applications, facilitating the development of safer and more reliable hydrogen storage systems.
