The steel pipelines introduced within the German gas are appropriate for transporting hydrogen.
They don’t vary in terms of their essential appropriateness for transporting hydrogen compared to natural gas. Both operational maturing and the desired fracture sturdiness compare to the desires of decades of dependable accessibility. Typically the result of the inquire about extend “Irregular testing of steel materials for gas channels and frameworks to survey hydrogen reasonableness” (SyWeSt H2) of the German Affiliation of Gas and Water Pros (DVGW). It was carried out by Open Network Europe and the Materials Testing Established of the College of Stuttgart.
“The research results point the way to the hydrogen future. Of the three challenges along the value chain – production, transport and utilization – transport has now been fundamentally solved. The pipes can continue to be used in pipeline networks, and only individual built-in parts or station elements have to be upgraded or replaced. This makes economic sense, because we can draw on an existing infrastructure with an investment volume of around 300 billion euros made over many decades. The federal government must now use this great potential and pave the way to the hydrogen economy in order to meet its claim for accelerated climate protection,” explains Prof. Gerald Linke, CEO of the DVGW.
Rather than building a unused gas arrange for the transport of hydrogen, the existing German gas arrange, which is more than 550,000 km long, can be changed over for the transport of hydrogen at a add up to fetched of as it were around 30 billion euros. Millions of family units and companies with a gas association are as of now H2-ready or can be made H2-ready with moderately small exertion and can hence be provided with 100 percent climate-neutral hydrogen through the existing infrastructure. To guarantee that there’s moreover total operational and legitimate certainty for this changeover, the DVGW has adjusted its set of rules for the utilize of up to 100 percent hydrogen and is right now including some more standards.
For the investigate venture, tests of the steel used in German pipelines were subjected to comprehensive estimation strategies that, compared to past ponders, take into account other factors such as the impact of hydrogen weight. These modern strategies empower more exact benefit life estimates and correspondingly longer unsurprising working times for pipelines, which at the same time permit superior arranging and maintenance of the gas arrange.
