Hydrogen embrittlement prevention and control [Part 4 of 4]

Hydrogen pipelines and trees stand for hydrogen embrittlement prevention and control.

At last, we reached the final delivery of our hydrogen embrittlement series. In part IV, we continue our interview with Material Testing Institute’s expert, Brain Kagay. Before, in part III, he shared precise insight into the effect of hydrogen embrittlement in different materials (metallic and non-metallic). Now, he’s disclosing more vital information relevant to the future blended operations of natural gas-hydrogen to be held in Germany’s existing grid and what’s next for research of hydrogen effects on materials.

Effects of hydrogen embrittlement on different valve materials [Part 3 of 4]

Hydrogen pipelines and trees stand for effects of hydrogen embrittlement on different valve materials.

Here is the third part of our hydrogen embrittlement series with special guest Materials Testing Institute’s expert Brian Kagay. In part II, we addressed the causes of hydrogen embrittlement in valves. So, naturally, in this installment, our conversation flowed toward the effects of embrittlement by H2 in different types of valve materials.

Causes of hydrogen embrittlement in valves [Part 2 of 4]

Hydrogen pipelines and trees stand for causes of hydrogen embrittlement in valves.

Welcome to the second delivery of our hydrogen embrittlement series. In this follow-up piece, our talk with Materials Testing Institute’s expert Brian Kagay turns to a new topic that complements part I’s basics of H2 embrittlement and its effects on valves. Here, the focus is on the causes behind valve embrittlement by H2. We also go over the enabling factors, how they impact the welding process, and the ways to spot affected materials.

Is hydrogen embrittlement a threat to valves? Get the answer here! [Part 1 of 4]

Hydrogen pipelines and trees stand for hydrogen embrittlement of valves.

Germany is hard at work on becoming a decarbonized region. The country found a scalable solution in hydrogen that favors all parts—the environment, citizens, and industries. To get the H2 initiative started, the government, with the help of the scientific community, is developing several macro projects. The first phase focuses on blended operations that lead to the controlled addition of hydrogen into the existing natural gas grid infrastructure.

Under such a novel context, it is natural to inquire about the potential implications of gas blending. How can the addition of hydrogen affect the existing systems? Is hydrogen embrittlement of materials a possibility? What are the causes? How to prevent it? These are rather important questions raised by plant operators. So, as valve manufacturers, AS-Schneider felt committed to taking action and finding answers. We sent our team to a one-on-one meeting with specialist Dr. Brian Kagay. His work in the prestigious Materials Testing Institute at the University of Stuttgart qualifies him as an expert in this subject. If you are a plant operator, you don’t want to miss out on what he had to say.
