Hydrogen is transported over long distances by road using trucks in which hydrogen is kept in liquid status (LH 2) in specialized tanks at cryogenic temperatures of 20 K. Owing to the considerable energy needed to liquefy hydrogen [319], [320], it is much more costly than gaseous hydrogen transportation and so is not now frequently employed to provide short …

hydrogen blending levels may not substantially affect the capacity of the gas infrastructure1. 3 » WHAT IS HYDROGEN DEBLENDING? Hydrogen deblending is the reverse process of hydrogen blending and allows to extract pure hydrogen for dedi-cated uses (e.g. hydrogen fuel cells, feedstock) as well as reasonably hydrogen-free natural gas. For hydrogen
Hydrogen purification by PSA can reach up to 99.999%, with a recovery range of 70–95% [80], [82]. Methanator is another alternative for hydrogen purification, but it is less efficient (∼98%) than PSA. The main barrier in SMR reaction is the thermodynamics, which favors high operating temperatures (700–900 °C) and low pressure (3–25 bar).
