Summary:Offshore subsea pipelines present a significant opportunity to repurpose oil and gas infrastructure by transporting hydrogen generated from wind power as the energy sector shifts away from fossil fuels. Long-term use of these pipelines to transport oil and gas raises questions about their viability in a hydrogen environment. Methane, the primary source of natural gas, must be replaced with hydrogen, but for that to happen, it must be mass-produced, cheap, and distributed safely. There would be no need to build a new hydrogen transmission network if hydrogen could be transported through existing gas pipelines. This study's objective is to comprehend what happens to the pipelines when open to hydrogen of high-pressure and related equipment. In my proposed presentation, I will carry out a pivot study of hydrogen transport in metals to see the pressure, temperature and flowrate effects, and embrittlement. The morphological and structural characteristics of the metal will also be studied to get an idea and a clear understanding of hydrogen transport in stainless steels pipelines.
