Suitability of existing natural gas pipelines for hydrogen transport - Risk of steel pipes to hydrogen embrittlement

Lecture Abstract

X

Development of new energy technology at full scale is critical to achieving the 2050 net-zero target. With the lack of a wide range of infrastructure to keep the new energy economy on a rapid-development trajectory, existing pipelines provide a promising alternative for effective and economic transport of new energies (fuels) such as hydrogen.

Safety is paramount for hydrogen transport by pipelines. Hydrogen embrittlement (HE) potentially occurs to compromise the structural integrity of steel pipes. This talk starts with an introduction of the benefits that pipelines provide for development of a full-scale hydrogen economy. The technical background of the HE phenomenon will be imparted, detailing unique features of the problem occurring in high-pressure gaseous environments, along with the effects of pipe steel metallurgy and stressing conditions. Technical gaps in repurposing existing pipelines for hydrogen service will be identified, and further actions are proposed to mitigate and control the HE occurrence.
