H2Life – Cryogenic test chamber for hydrogen fatigue

Development of a cryogenic test chamber system for testing and qualifying materials and compo-nents for the hydrogen economy at high and very high fatigue lifetimes of up to 500 million cycles in contact with liquid hydrogen at -253 °C

For materials and components under fatigue loading in LH2 contact, no systems for testing and qualification in terms of mechanical properties and lifetime are available so far.

Within this project, a novel testing methodology and a novel, instrumented test chamber system will be developed to evaluate the influence and interaction of hydrogen embrittlement and low-temperature conditions on the fatigue behavior and damage development of established and new materials, composites and components while liquid hydrogen is used as a CO2-neutral energy carrier. In addition, the material and component qualification for a CO2-neutral economy based on hydrogen or liquid hydrogen is being carried out.

With this innovative new development, industrial users and research institutes can be provided with a powerful measuring and testing system for characterizing the High Cycle Fatigue (HCF) and Very High Cycle Fatigue (VHCF) behavior of LH2 materials and components.

Duration: 2022 until 2024
