Hydrogen pipeline transport is a transportation of hydrogen through a pipe as part of the hydrogen infrastructure.

History[edit]

Economics[edit]

Hydrogen pipeline transport is used to transport hydrogen from the point of production or delivery to the point of demand. Although the technology for hydrogen pipeline transport is proven,[5][6] and the transport costs are similar to those of CNG,[7] most hydrogen is produced in the place of demand, with an industrial production facility every 50 to 100 miles (80 to 161 km)[8]

Piping[edit]

Hydrogen has problems with both hydrogen embrittlement and corrosion. Hydrogen has an active electron, and therefore behaves somewhat like a halogen.[9] For this reason, hydrogen pipes have to resist corrosion. The problem is compounded because hydrogen can easily migrate into the crystal structure of most metals.[10] For metal piping at pressures up to 7,000 psi (48 MPa), high-purity stainless steel piping with a maximum hardness of 80 HRB is preferred.[11]

Composite pipes are assessed like:

Fiber-Reinforced Polymer pipelines (or FRP pipeline) and reinforced thermoplastic pipes are researched.[12][13][14][15]

Infrastructure[edit]

  • 2004 - USA - 900 miles (1,400 km) of low pressure hydrogen pipelines[16][17]
  • 2004 - Europe - 1,500 km (930 mi) of low pressure hydrogen pipelines.[18]
