Why is there a need for new hydrogen embrittlement test systems?
Hydrogen plays a prominent role in all future scenarios of the energy industry. As a connecting element between the different areas of energy supply, hydrogen contributes to the sustainable conversion, storage and use of energy. Hydrogen technology supports the expansion of renewable energy systems and the avoidance of CO2 emissions. Regarding production and operation, hydrogen stored in atomic form can trigger structural damage mechanisms that cause component failure. Therefore, in order to ensure safe operation and a long service life of systems in contact with hydrogen, diffusion, reaction and damage processes must be taken into account during the development, production and use of many materials, especially high-performance materials in contact with hydrogen.
An advanced description and evaluation of the effects of hydrogen regarding materials takes into account mechanisms on both the macroscopic and microstructural scales as well as on the atomic scale and translates these mechanisms into reliable life cycle predictions and risk assessments. It is precisely these requirements that the Fraunhofer Institute for Mechanics of Materials IWM - via its research and development focus on materials in contact with hydrogen – satisfies and fulfills.
Our research and development work aims to describe interactions of atomic or molecular hydrogen in contact with materials using experimental methods and theoretical models: adsorption, desorption, dissociation and association of gases or fluids containing molecular hydrogen on material surfaces, absorption, permeation, diffusion and reaction of atomic hydrogen in material structures. This enables us to provide a target-oriented mechanistic description of damage processes, an evaluation of material and component behavior and the derivation of design guidelines and life cycle predictions.
We are using the workshop "Influencing the effects of hydrogen on materials" as an opportunity to present current solutions for the use of materials in contact with hydrogen as well as to discuss future-oriented concepts with prominent representatives from industry and science.
At the Fraunhofer IWM, we have considerably expanded our ability to provide practical and theoretical opportunities for material-hydrogen mechanics: new laboratory facilities, new experimental techniques and new simulation tools, which will be presented as part of this workshop.
