Within the Lifetime Concepts for Hydrogen Applications group, methods for evaluating the lifespan of components in contact with high-pressure hydrogen are developed and applied.
The basis for component evaluation relies on established guidelines such as the FKM guidelines, the pressure vessel guideline AD2000 or EN13445, or the American pipeline guideline ASME B31.12, which have been partially expanded to consider the damaging influence of hydrogen. A more detailed assessment of components is carried out using Finite Element Methods (FEM), which utilizes the experimental determination of material properties within hydrogen environments.
