Hydrogen can be produced, among other methods, through steam reforming or water electrolysis. For climate-friendly “green” hydrogen, the electricity required for water electrolysis is based on regenerative sources such as wind or solar energy. Cryogenic processes play an important role in hydrogen processing, as hydrogen has a low molecular mass and only liquefies at temperatures below -253 degrees Celsius. Liquefaction of hydrogen enables efficient handling, because thanks to its higher density, hydrogen in liquid state can be stored more effectively and transported more easily to its destination. Valves used in hydrogen infrastructure must withstand extreme pressures and temperature ranges and therefore exhibit particular toughness. As an expert in industrial valves, Siekmann Econosto places high demands on the material selection for individual valve components. The company relies on external testing of materials in a specialized laboratory to ensure maximum valve safety.

The materials are tested for sufficient ductility within the framework of the Charpy Impact Test (notch impact strength test) at an impact temperature of -269 degrees Celsius with special testing equipment. The ductility of the material is a prerequisite for the safety of the entire process.
