Abstract
A system and method for transporting and distributing hydrogen, reducing the risk of hydrogen leakage, maintaining a record of provenance, and measuring and recording its purity level as it flows from source to destination to assure it complies with a predetermined range of values. The system includes a hydrogen delivery line made from metallic or non-metallic pipe that may be placed inside a safety pipe such that a channel is formed between an exterior of the hydrogen delivery line and an interior of the safety pipe. A sweeper gas or liquid may be injected into the channel to purge any hydrogen that might escape from the hydrogen delivery line, and one or more sensors may be used to detect and avoid the presence of an unacceptable level of hydrogen, or to stop the flow of hydrogen and remediate the problem well before a safety or environmental risk can occur.
