Actually I've been thinking it's time for me to go. I wouldn't have these conversations with folks like y'all in real life so why bother on the internet? I do wish I could send you some of our deranged politicos.

LOL,thanks but I can't afford to live in the PNW! Interesting and sad that you think you are able guess my politics by my posts about climate change. Maybe ask yourself why one of our political parties became anti-science.

Not sure what NG pipelines are made of but there’s the issue of Hydrogen Embrittlement.
Per Wikipedia;
Hydrogen embrittlement (HE), also known as hydrogen-assisted cracking or hydrogen-induced cracking (HIC), is a reduction in the ductility of a metal due to absorbed hydrogen. Hydrogen atoms are small and can permeate solid metals. Once absorbed, hydrogen lowers the stress required for cracks in the metal to initiate and propagate, resulting in embrittlement. Hydrogen embrittlement occurs most notably in steels, as well as in iron, nickel, titanium, cobalt, and their alloys. Copper, aluminium, and stainless steels are less susceptible to hydrogen embrittlement.[1][2][3][4]

“ Another factor is the integrity of the steel pipes and fittings. Depending on the quality of the steel and potential exposure to atomic hydrogen, in principle, embrittlement can accelerate propagation of cracks, reducing the pipeline’s service life by 20 to 50 percent. This is only likely, though, if the pipeline already has fractures and is subjected to dynamic stresses due to fluctuating internal pressure while at the same time being exposed to atomic hydrogen. The confluence of all three factors seems unlikely, however: Under normal operating conditions, there should be little load alternation, and only molecular hydrogen (H2).”
