Hydrogen embrittlement (HE) is a major challenge limiting the durability of high-strength materials exposed to hydrogen-rich environments. This paper presents a comprehensive analysis of advanced material strategies aimed at mitigating HE, including the development of multi-principal element alloys (MPEAs), nanostructured materials, and protective coatings. The study investigates the role of grain boundary engineering, carbide precipitation, and diffusion barriers in reducing hydrogen ingress and improving mechanical resilience. Experimental case studies on cadmium-plated fasteners and boiler tubes highlight the effectiveness of these approaches, with graphical analysis demonstrating significant reductions in ductility loss, crack propagation, and material degradation. The findings emphasize the necessity of integrating computational modeling, experimental validation, and industrial applications to enhance material performance in hydrogen-intensive sectors. This research provides a foundation for future advancements in hydrogen-resistant materials, contributing to the development of a safer and more reliable hydrogen infrastructure.
