Developing a condition monitoring technique for hydrogen storage vessels
In this project, a technique based on ultrasound measurements will be developed, that together with modern machine learning techniques, can be used to monitor changes in the welded joints over time.
"Safe and reliable storage of Hydrogen is one of the keys for Hydrogen to be an accepted energy source. Part of the solution is to enable continuous monitoring of the storage vessels", Johan Carlson says, Professor of Signal Processing at Luleå University of Technology.
Enabling a shift to fossil free steel production through the HYBRIT process requires that all parts of the Hydrogen value chain is well developed. In addition to production and use of Hydrogen in the steel production process, this also involves storage and transportation of Hydrogen. Storage is known to be challenging due to Hydrogen embrittlement (HE), also known as hydrogen-induced cracking. When constructing Hydrogen storage vessels, several parts are welded together. From a structural integrity point of view, the welded joint is likely to be the weakest point.
Safe long-term operation therefore requires novel non-destructive weld condition monitoring systems to be developed. In this project, a technique based on ultrasound measurements will be developed, that together with modern machine learning techniques, can be used to monitor changes in the welded joints over time.
