According to a media report, the German gas industry has achieved a breakthrough in the nationwide introduction of hydrogen. "The issue of efficient and large-scale transport of hydrogen has been solved in principle," says a letter from the Association of the Gas and Water Industry (DVGW) to the Federal Government, from which the newspaper "Welt am Sonntag" quotes.
Accordingly, the resistance, wear behavior and crack propagation of more than 30 of the most frequently installed steels in the gas network in Germany were examined over several years. A summary states that the DVGW study shows that the operating behaviour during the transport of hydrogen under the normal operating conditions in gas supply networks does not differ from that of natural gas.
The remaining service life of the installed pipelines for operation with pure hydrogen is about 100 years. The study results are transferable to the entire German gas network.
