Hydrogen pipelines are made of metal or plastic and are used to distribute hydrogen either through existing natural gas infrastructure or by building new pipelines solely for the transportation of hydrogen.

Building new hydrogen pipelines requires a significant initial investment, but it is probably the easiest way to distribute the gas. On the other hand, the use of existing natural gas infrastructure requires lower initial costs, but care must be taken to ensure that the right proportion of hydrogen is in the gas mix. Further investment in technology to separate the hydrogen from the natural gas once it reaches its destination is also required. [18] Transportation of hydrogen through pipelines is advantageous at the point of production to supply a hydrogen filling station designed for internal transport vehicles or to supply a public hydrogen filling station located in the vicinity of the hydrogen production.
