About the position

Are you motivated to take a step towards a doctorate and open up exciting career opportunities? As a PhD Candidate with us, you will work to achieve your doctorate, and at the same time gain valuable experience that qualifies you for a further career in higher education and research, in and outside academia.

A PhD position is available at the Department of Mechanical and Industrial Engineering with the Materials & Manufacturing research group.

Your immediate leader will be the Head of Department. You will be supervised by Adjunct Professor Ole Øystein Knudsen, along with project coworkers from NTNU and SINTEF.

About the project

Hydrogen embrittlement poses a major challenge to the safety and reliability of hydrogen infrastructure. Metallic materials exposed to hydrogen gas may experience reduction in strength, ductility, and resistance to fatigue and fracture. This is especially critical for pipelines and storage vessels, where hydrogen can penetrate metals, leading to premature failure.

The “ReSIstH2” project aims to develop advanced metal barriers that improve the integrity of hydrogen infrastructure. To address hydrogen embrittlement, metal barriers—such as aluminium alloys and austenitic stainless steels—are employed to prevent hydrogen ingress and protect the structural integrity of carbon and low alloy steels. To ensure their effectiveness, the project will investigate how these barriers interact with hydrogen—studying uptake, diffusion, and mechanical performance—while also optimizing cladding and lining techniques for improved resistance to hydrogen degradation. Ultimately, this research aims to contribute to safer and more sustainable hydrogen storage and transport solutions.

As part of this effort, this PhD research focuses on the absorption and diffusion of hydrogen in these metal barriers exposed to hydrogen gas environments. Through a combination of experimental testing, theoretical analysis, and numerical simulations, the study aims to characterize the effect of mechanical loading on surface oxide integrity and hydrogen permeation dynamics. A high-pressure gaseous hydrogen diffusion cell with instrumentation for load application will be employed.

The position is financed by the Research Council of Norway’s on robust metal barriers for “Safe use of Hydrogen Infrastructure” (ReSIstH2). The project is a collaboration between SINTEF, NTNU and industrial partners.

Duties of the position

Investigation of gaseous hydrogen absorption and diffusion in various metal alloys under mechanical loading
Characterization of microstructure and surface oxides of the selected alloys
Complete the doctoral education until obtaining a doctorate
Carry out research of good quality within the framework described above
Academic publications and popular science dissemination
Participate in conferences and/or research stays at foreign educational institutions
Co-supervision of master students on the topic of the PhD project

Be prepared for changes to your work duties after employment.
