The effect of hydrogen transported through a gas pipeline on the functioning of gas compression station work

Hydrogen Blending into Natural Gas Pipeline Infrastructure: Review of the State of Technology

“…Several effects of blending hydrogen relating to compression thermodynamics can impact both reciprocating and centrifugal compression technologies. Compression work and theoretical temperature rise both increase with hydrogen concentration when considering compression at constant pressure rise and inlet temperature (Bainier and Kurz 2019;Zabrzeski et al 2017). The increase in compression work is primarily attributed to the decrease in density, while the increase in temperature rise is due to an increase in heat capacity ratio (the ratio of the specific heat at constant pressure to the specific heat at constant volume) as gas composition changes.…”
