Noone here is planning to inject hydrogen into existing pipelines. If anything, synthesising methane during the transition so that consumers only have to switch their burners once, from nat gas to hydrogen, and not first to nat gas + more hydrogen and then to pure hydrogen. Gotta switch whole municipalities at once doesn’t make sense to duplicate the last-mile gas pipes. If, and that’s not even clear yet, hydrogen pipes will even be a thing for private consumers.
And here we have a typical specimen exhibiting capitalist realism: Observe how the subject is analysing everything they come across on a “who works for who” basis, projecting human modes of production onto the universe. Applying it, even in vain, this reductive universality ensures that they will never think beyond it and, not thinking beyond it, not question either working for a capitalist or being a capitalist who is worked for, thereby in either case working for capitalism, a form of human cooperation in which happiness, well-being, yes even human connection (that necessitating eye-level communication) is traded for hastened advancement of the economy to achieve post-scarcity.
