Hydrogen Series Part 3: Hydrogen compression and transportation by transmission pipeline – What are the impacts of Hydrogen blending on the physical properties of hydrogen and natural gas?
In continuation of Feb and Mar 2023 “Tips of the Month” (TOTM) and given the amount of investment and interest in hydrogen, we have decided to publish a series of TOTM to explore the opportunities, challenges, and potential solutions to hydrogen applications and uses; this is the third paper in the series. In this TOTM we will review the physical properties of hydrogen and natural gas, which are quite different from one another. These differences govern the hydraulics of pipeline transmission. Specifically, we will discuss the impact of blending hydrogen on natural gas properties like higher heating value and the Wobbe Index, and the need for accurate gas mixture property estimation for reliable model representations of the pipeline system. Our future tips will explore the possible end uses and benefits of hydrogen, thermodynamics of natural gas use versus hydrogen in industrial applications, safety considerations, transportation challenges and opportunities, storage, and end use capabilities. In addition, we will look at some cost comparisons, where possible of the different hydrogen production options. We hope you enjoy taking this journey with us. Our aim is to take a thermodynamically balanced non-biased view of possible applications, costs, and implications. [Keep reading]
