Hydrogen could gradually replace fossil fuels, mitigating the human impact on the
environment. However, equipment exposed to hydrogen is subjected to damaging effects …

Existing natural gas pipelines provide an economic alternative for the transport of hydrogen
(H2) in an envisioned hydrogen economy. Hydrogen can dissolve in the steel and cause …

We are reporting in this study the hydrogen permeation in the lattice structure of a steel
pipeline designed for natural gas transportation by investigating the influence of blending …

The hydrogen compatibility of two X65 pipeline steels for transport of hydrogen gas is
investigated through microstructural characterization, hydrogen permeation measurements …

Due to non-pollution and high combustion efficiency, hydrogen energy is promising as a
clean and renewable energy source to gradually replace fossil fuels and reduce carbon …

We combine welding process modelling with deformation–diffusion–fracture (embrittlement)
simulations to predict failures in hydrogen transport pipelines. The focus is on the structural …

In this study, the effects of hydrogen on the fracture toughness and crack propagation of X80
steel base metal and girth weld were assessed. The crack tip opening displacement (CTOD) …

Previous research has indicated that hydrogen decreases the fracture toughness of gas‐
transmission pipeline steels. This study produced two values of fracture toughness for the …

Currently, no systematic approach exists for the safety assessment method of hydrogen
transmission low-strength pipeline, it is necessary to study the effect of hydrogen …
