Abstract

Hydrogen storage and transport systems rely on pressurized components operating under high pressure, cyclic loading, and hydrogen-rich environments that accelerate degradation mechanisms such as corrosion, micro-cracking, and hydrogen-assisted damage. Early detection of subsurface and internal wall defects is therefore essential to ensure structural integrity and operational safety. This study presents a nondestructive evaluation framework based on ultrasonic guided waves for structural integrity assessment of hydrogen energy components. Experimental investigations are conducted on a laboratory-scale stainless steel pressure vessel containing controlled internal-wall crack-like defects. Guided wave signals are analyzed in the time domain to examine wave-damage interaction effects, including scattering and amplitude variations. To enhance defect sensitivity, continuous wavelet transform is applied to generate time-frequency scalograms, from which damage-sensitive features are extracted for health condition characterization. The results demonstrate that guided waves can detect and characterize geometrically complex and subsurface flaws using sparse sensor configurations, enabling efficient large area monitoring. The proposed methodology supports the development of intelligent structural health monitoring systems for hydrogen infrastructure, contributing to improved safety, reliability, and lifecycle management of critical energy assets.
