Stacking solutions for hydrogen applications

Hydrogen plays an essential role in our transition to climate neutrality, as it is the clean fuel of choice. Swiss Steel Group not only plans to use hydrogen as a process gas, but also offers steels that support this challenging transition process.

Hydrogen challenge

The global demand for energy is constantly increasing, but cannot be met by direct renewable energy sources such as wind and solar power alone. The use of fossil fuels to generate energy has a significant impact on the global climate.  Swiss Steel Group is actively committed to climate protection. In addition to the planned use of hydrogen as a process gas, Swiss Steel Group's steels will support this challenging transition process.

The production, processing, storage and use of hydrogen places great demands on the materials. These must be extremely resistant in order to withstand high pressures as well as extremely low and high temperatures. Stainless steels, especially austenitic grades, are ideally suited to these challenges.

Our research center in Ugine (France) is distinguished by its expertise in the development and characterization of stainless steels. The focus here is on investigating the hydrogen embrittlement of stainless steels. The H2S laboratory at the research center has also gained experience with hydrogen sulphide embrittlement phenomena, particularly in the oil and gas industry.

Stacking solutions for hydrogen production

Stainless steels play a crucial role in efforts to tackle climate change due to their excellent resistance, particularly to corrosion, and their high performance. However, the choice of material is crucial: depending on requirements, either stainless steels or structural steels can be used.

  • Standard solution for stainless steels: Acidur®4435H2 / UGI®4435H2
  • For higher yield strength requirements, we recommend Acidur®3964H2 / UGI®209H2, Magnadur®601H2 and UGI®4944H2 
  • The new Acidur®4636H2 offers similar properties to Acidur®4435H2 / UGI®4435H2, but is more economical due to the alloying elements used.

These austenitic steels are particularly suitable for tank valves, sensors in fuel cells and electrolyzer valves in hydrogen production.
