Hydrogen Embrittlement in Pipeline Steels and Welds
, 2022 In the energy transition towards a low carbon economy, the EU strives to provide a hydrogen grid of almost 23000 km by 2040. 75% is expected to be obtained by retrofitting existing pipelines for the transport and storage of hydrogen gas. However steels are prone to hydrogen embrittlement, i.e., hydrogen reduces their ductility and fracture toughness ...
