TÜV Rheinland has introduced a new hydrogen certification. The certification attests to the suitability of materials used in critical applications such as pipelines and pressure vessels in large industrial plants for use with pressurized hydrogen. The "H₂-ready" test mark aims to increase safety in the hydrogen industry. The first companies have already received certification.
TÜV Rheinland has introduced a new certification standard. The "H2.23" certification focuses on the safe operation of pipelines and plant components with pressurized hydrogen. The "H₂-ready" test mark confirms the technical suitability of components for handling pressurized hydrogen.
Gunther Sproesser, materials expert at TÜV Rheinland, explained: "Our new 'H2.23' standard combines the current state of technology with global expert knowledge to test materials for their hydrogen compatibility."
After successful certification, manufacturers receive the "H₂-ready" test mark. This allows them to document to customers that their materials are safe for use with pressurized hydrogen. Only materials that meet strict criteria receive the "H₂-ready" test mark. The test mark also requires regular monitoring of production.
First Certificate Already Awarded
In Germany, there has been a lack of recognized regulations for the permanent and safe use of components with pressurized hydrogen, Sproesser said. TÜV Rheinland now wants to fill this gap. Through the new "H₂-ready" certification, the testing service provider aims to ensure more safety and trust in the rapidly growing hydrogen industry.
One of the first customers was "Busch + Kunz". TÜV Rheinland has already certified several materials from the fitting manufacturer according to the "H₂-ready" standard.
The challenge in using the gas: Compared to methane, hydrogen molecules are significantly smaller. As a result, they can diffuse more easily through materials. This means hydrogen can penetrate materials. There, the molecules can cause hydrogen embrittlement and corrosion, leading to micro-cracks and fractures, which can result in component failure. Consequently, leaks and the escape of hydrogen can occur.
