摘要

Pipelines are the most economical and efficient means for large-scale, long-distance transport of hydrogen gas, helping accelerate the realization of a hydrogen economy. Today, the development of hydrogen pipeline projects, including repurposing existing pipelines for hydrogen service, has become a global focus, especially in major energy producing and consuming countries. However, steel pipelines are prone to hydrogen embrittlement (HE) in high-pressure gaseous hydrogen environments, which can lead to pipeline failure. Drawing on published work, we assemble a curated knowledge base that distills how gaseous hydrogen embrittlement in pipelines is understood, characterized, and evaluated.
