ABSTRACT Transport of hydrogen in blended form in existing natural gas pipelines contributes to the accelerated realization of a full-scale hydrogen economy. However, steel pipelines are considered susceptible to hydrogen (H)-induced degradation (HID) in high-pressure gaseous hydrogen environments. This work develops a critical review of the up-to-date progress in pipeline HID research between 1994 and 2024, defining the spatiotemporal distributions of research publications, featured researchers and their affiliations, and thematic topics. Pipeline HID research encompasses five themes: (i) hydrogen (H) atom generation, (ii) adsorption and absorption of H atoms, (iii) diffusion and trapping of H atoms in steels, (iv) HID mechanisms, and (v) hydrogen-induced pipeline failures and integrity management. Specific disturbance factors for resilience assessment on hydrogen pipelines are identified, and the evolution of research methods and test approaches is reviewed. There is a rapid increase in pipeline HID research, with the number of relevant publications from single digital to over 60 per year. The publications are mainly from Asia (47.7%), Europe (23.1%), and North America (20.6%), where China (53) contributes the most literature on pipeline HID in Asia. Of the top sixteen institutions contributing to HID research, there are five located in China. Currently, the primary knowledge gap lies in reliable assessment and effective control of HID-related risks to pipelines for timely ...
