During the design and operation of main pipelines, all potential hazards related to hydrogen (H₂) transportation must be taken into account to assess the risks of emergencies. Pipeline damage can lead to uncontrolled combustion, causing significant material damage to enterprises, posing threats to human health and life, and affecting national interests. The key factors disrupting the integrity of transporting methane-hydrogen mixtures (MHMs), in which H₂ is a predominant component, include the phenomenon of hydrogen embrittlement of pipeline steel and the equipment used for gas transportation. This article analyzes scientific research on the effects of hydrogen embrittlement on pipeline steel intended for MHM transportation. Additionally, recommendations are provided for preventing emergency situations in pipelines. These recommendations are based on a comprehensive study of the compression processes of MHMs and an assessment of safety threats and rely on the data collected from open sources.
