Gunther Sproesser, Materials Expert at TÜV Rheinland, explained: "Our new 'H2.23' standard combines the latest technology with global expertise to test materials for hydrogen compatibility." The challenge: hydrogen can penetrate materials, making them brittle and damaging them to the point of component failure. Upon successful certification, manufacturers can receive the 'H2-Ready' test mark to demonstrate to customers that their materials can safely handle compressed hydrogen. The H2-Ready test mark is only awarded to materials that meet strict criteria. The mark also requires regular monitoring of production.
"In Germany, there is a lack of recognised regulations for the long-term and safe use of components with pressurised hydrogen. We are filling this gap with the 'H2-Ready' certification. In doing so, we are ensuring greater safety and confidence in the rapidly growing hydrogen industry," said Sproesser. TÜV Rheinland has already certified several materials from Busch + Kunz, the leading European manufacturer of weld fittings, in accordance with the 'H2-Ready' standard.
