133191 - A Resilience Evaluation Framework for Hydrogen Pipeline System 

Abstract: 

The prevalent reliance on fossil fuels has resulted in the release of greenhouse gases, exacerbating global climate change and environmental decline. In pursuit of a net-zero emissions future, hydrogen energy emerges as a pivotal and sustainable solution. Recognized as a critical energy carrier, hydrogen's promise is evident in its potential to foster clean energy practices. The utilization of high-pressure steel pipelines is widely acknowledged as the safest and most cost-effective means of large-scale hydrogen transportation. Yet, the interaction between hydrogen atoms and pipeline steel in high-pressure environments introduces challenges such as hydrogen embrittlement, hydrogen-induced cracking, and hydrogen blistering, posing a risk of accidents. The repercussions extend beyond energy loss and carbon emissions, potentially leading to severe injuries or even fatalities. Previous research has predominantly explored this interaction through the lens of material science, focusing on the properties of pipeline steel. This study shifts the perspective by considering the pipeline as a structure, emphasizing the evaluation of its performance in terms of integrity. Resilience, encompassing vulnerability, robustness, and the capacity to recover from disturbances, provides a comprehensive framework for assessment. Bridging engineering resilience research with the unique characteristics of hydrogen-induced degradation, the present study introduces a definition and metrics for hydrogen pipeline resilience. The proposed evaluation framework goes beyond traditional integrity and reliability assessments, offering insights to customize effective recovery strategies. Integrating resilience research into the study of steel pipeline performance opens avenues for addressing limitations and optimizing solutions. Aimed at policymakers, regulatory agencies, and stakeholders, this study establishes a method to evaluate the resilience of hydrogen pipelines. Additionally, it charts a course for future research, guiding efforts to assess, optimize, and enhance the resilience of hydrogen transportation infrastructure. This study may contribute to developing and refining strategies that foster the sustainable and secure integration of hydrogen energy into our global energy landscape.
