Gaseous inhibitors: A comprehensive overview on mitigating hydrogen embrittlement in pipeline steels

Published in International Journal of Hydrogen Energy, 2024

This work reviews hydrogen embrittlement risks in pipeline steels during hydrogen transport and explores mitigation using trace inhibitor gases like oxygen and carbon monoxide. It examines surface interactions, showing inhibitors slow hydrogen adsorption but cannot stop equilibrium absorption, requiring continuous supply. The study highlights how factors such as test type, pressure, and inhibitor concentration affect mitigation effectiveness.

Linking microstructure to fracture morphology under hydrogen charging in L485MB pipeline steels

Published in The Energy Pipeline Innovation Conference (EPIC 2025), Cambridge, United Kingdom, 2025

Hydrogen affects the mechanical properties of pipeline steels. The underlying microstructure often governs the severity of hydrogen-assisted degradation. This work uses ex-situ quasi-static tensile tests to study the hydrogen performance of two cold-bent L485MB pipeline steels with different banding morphologies.

A comprehensive overview of hydrogen transport in existing pipelines and mitigation of hydrogen embrittlement by gaseous inhibitors

Published in EUROCORR 2025, Abstracts, Stavanger, Norway, 2025

The transition of existing natural gas infrastructures to transportation and storage of sustainable hydrogen gas is crucial for the global decarbonization of the energy sector. However, hydrogen absorption in pipeline steels can degrade their mechanical properties, necessitating prior confirmation of the fitness-for-service of existing pipelines for pressurized hydrogen transport. This work presents a literature overview on the relevant aspects of hydrogen embrittlement (HE) in pipeline steels and its mitigation through addition of inhibitors. Hydrogen-assisted fatigue crack growth, which occurs under cyclic loading even at low hydrogen partial pressures, is considered to be a significant failure mode in pipeline steels transporting hydrogen gas, leading to potential lifetime reduction. Mechanical, environmental and material variables can all influence the severity of HE. Gaseous additives, such as oxygen or carbon monoxide, have shown potential in mitigating HE by slowing hydrogen adsorption kinetics. However, sustained mitigation requires continuous supply of these inhibitors.

Characterization of Secondary Carbides in Low-Alloyed Martensitic Model Alloy Tool Steels

Published in Swerim AB, KTH Royal Institute of Technology, 2020

This master thesis studies tool steels with iron, carbon, molybdenum, and vanadium to understand carbide effects on hardness. Two alloys were tempered at 550C and 600C, with hardness measured and compared. Alloy A was analyzed with STEM EDS and TC Prisma simulations, showing molybdenum carbides increase strength. Hardness was higher at 550C due to reduced overaging at 600C.
