I think the idea is that if the infrastructure for hydrogen fuel exists and using fossil fuels is penalized, there’s an incentive to start producing more of it via electricity by, as an example, using excess power produced by renewable energy sources when demand is low, balancing the grid and leveling out electricity price fluctuations at the same time.
This relies on a lot of technical, economical, and political ifs though. The end goal is desirable but it’s not clear if there’s a feasible path there, considering the physical properties of hydrogen alone.
Difference being that unlike sexual orientation, desire to have children is something that can be affected quite a lot by just situational circumstances. I’m glad to hear that it worked out well for you, but there are plenty of people who have either wanted or not wanted children when young who have ended up changing their minds, to my knowledge there’s never been an instance of anyone changing their sexual orientation.
