These pipelines have generally operated at less than 1,000 pounds per square inch (psi), with a good safety record. Pure hydrogen pipeline now exceeded 2500 km in the USA, where Air Products have been operating the longest hydrogen pipeline from Texas to Louisiana at over 983 km.

Abstract. Normal hydrogen is a gas at atmospheric conditions (15 C., 101.325 kPa absolute; 60 F., 14.7 psi). The hydrogen pressure is generally 2~10MPa, the diameter of the pipes is 0.3~1.5m, and the pipeline materials are mainly X42, X52, X56, X60, X65, X70, X80 and other low strength pipeline steels. The expected service life is 15~30 years. CSD cost for the distributed production scenario is between $2.30/kg and $3.20/kg, with a projected cost of $2.70/kg of hydrogen. December 2018; 140(6): 061702. https://doi.org/10.1115/1.4041689. The 1.6-in. inner diameter is much smaller than would be expected for a pipeline operating at typical lower pressures of 2001500 psi, because the higher pressure makes the hydrogen behave more like a liquid. The liquid-like behavior enables a small-diameter pipeline to meet the pressure-drop requirements. https://www.wldsteel.com/wp Hydrogen is typically stored in steel cylinders without problems.
