Hydrogen would be a viable alternate use for the pipelines in the long term. There are some promising projects going on in Alberta for producing hydrogen in less carbon intensive ways.

- mjevans 5y agoHydrogen is even smaller than helium, which is used for leak testing vacuum systems. I hypothesize that a hydrogen leak is less destructive than an oil leak, but that's still a problem.
- neltnerb 5y agoMaking a pipe leak tight to hydrogen versus leak tight to oil is not even playing in the same ballpark. Hydrogen leaks through practically everything, oil is viscous. Plus hydrogen burns much more easily and the flame is transparent.
- ivalm 5y agoAtomic radius of helium is smaller than hydrogen 31 vs 53 pm. Hydrogen gas is also typically in the form H2, which is much larger. At the same time ofc oil pipelines will still be too leaky.
- randymercury 5y agoFavoring a shotgun approach towards GHG emissions downstream is there a better approach towards building an infrastructure distributing hydrogen? That question isn't intended as rhetorical
- simbas 5y agoIt seems it's hard to transport pressurized hydrogen in pipelines as hydrogen embrittles steel. Gas utilities are trying to implement this to lower the carbon footprint of their gas (when hydrogen comes from renewable sources). https://en.wikipedia.org/wiki/Hydrogen_embrittlement https://en.wikipedia.org/wiki/Hydrogen_embrittlement
