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.

New EU steel safeguard measures change framework conditions for Steeltec

The European Union (EU) has adopted new steel safeguard measures that will enter into force on July 1, 2026. Duty-free import volumes into the EU will be reduced by 47% from 34.5 million tons to 18.3 mil-lion tons. Imports exceeding these quotas will be subject to a tariff of 50%, up from the previous rate of 25%. The measures apply to steel producers from third countries, including Switzerland, exporting products into the European Union. Steeltec AG, based in Emmenbrücke and part of Swiss Steel Group, is among the companies affected by the new regime.

Firmly anchored in the rock - Swiss Steel Group’s Top12 anchors secure a new section of road high above Lake Lucerne

100 years – that is the lifetime expected for the new section of the K2b cantonal highway between Vitznau and Gersau following its renovation and modernization. This is made possible in no small part by the Top12 special stainless steel from the Swiss Steel Group, from which the anchors for the retaining wall structure and support elements are manufactured. Over a hundred of these were drilled several meters deep into the steep rock face. They secure the walls and beams that support the new, 350-meter-long section of road. The structure is spectacular not only from a geotechnical perspective but also for everyone who drives over it and enjoys a breathtaking view of Lake Lucerne below.
