Study, Modelling and Computing of Pressure Losses in GH2 Pipelines

The Wallonia region of Belgium aims to transition to a modern hydrogen infrastructure. Since hydrogen is much lighter than natural gas, so it is important to understand its nature and behavior while transporting through pipelines. This research aims to observe the pressure loss in pipelines due to surface roughness with H2 and other singular losses to find a solution to minimize the amount of pressure loss that occurs during transportation. This study involves numerical methods and gas equation models to determine thse pres-sure loss. This analysis includes the properties of hydrogen gas, pipeline material used, friction factor, pipeline efficiency, and other relevant properties of hydrogen and the pipe-lines. To address this challenge, this study integrates numerical fluid dynamics methods with structural modelling of pipeline walls. It accounts for long-term friction effects, erosion over several years, radial pressure gradients (mixing pressure drop), acceleration effects, and gravity influences, considering the non-ideal behavior of gaseous hydrogen (GH2).
