Permeation, Pressure Cycling, RGD: Challenges Seals Have to Cope With

From production to application, hydrogen puts materials and components under extreme stress—and sealing technology often makes the difference between a promising concept and a robust, safe system.

Hydrogen is pivotal to the energy transition—but making it work at industrial scale depends on details that are easy to overlook. In this episode of “Alles dicht?!”, host Holger Best talks with Artur Mähne about why seals are evolving from simple C-parts into safety-critical components. They trace the hydrogen value chain from electrolysis to compression, transport and end use, unpacking challenges such as permeation, pressure cycling and explosive gas decompression (RGD). Learn how data-driven validation, simulation and application-focused testing help turn demanding requirements into reliable, efficient systems.
