The proposed european transmission and distribution of hydrogen will likely need lots of pipelines.  Repurposing extant ones to deal with embrittlement issues will be required.

Conversely, in pipeline systems, hydrogen with its smaller density shows a flow velocity that is up to three times higher than that of methane. This means that the same pipeline can convey three times as much hydrogen during a given period at the same pressure, while the energy transportation capacity is only slightly smaller.

This is interesting-- so to get the same energy results with all hydrogen compared with gas, we'd still need more pipelines
