Description

The costs of different pipelines can be compared by converting different units to the same unit which refers to the volume of gas that is transported per hour.

Based on this common unit, the costs of hydrogen pipelines seem too low taken into account:

  • far less experience with hydrogen pipelines in comparison with NG gas pipelines
  • hydrogen needs bigger and more compression stations
  • hydrogen is a very small molecule and can leak easily
  • hydrogen causes hydrogen embrittlement which requires different materials and will reduce the lifetime

Furthermore, the techno-economic parameters of repurposed pipelines don't seem correct since the cost should be based on the NG pipeline cost combined with the conversion cost.

First steps

  1. Read the whole issue, then the project's contributing guide.
  2. Comment on the issue to say you are picking it up — it saves two people doing the same work.
  3. Fork the repository and make your change on a branch.
  4. Open a pull request that references the issue number.

Research direction

Start by reviewing the repository's pipeline techno-economic parameter data and the unit-conversion assumptions used to compare costs. Compare hydrogen and repurposed pipeline entries with the concerns in the issue; done requires agreed parameter values and supporting rationale, but the issue names no files or tests and has no recent response.
