I think people can and should build a system that extracts Hydrogen from Water and expels Oxygen as a byproduct, how about that?

You mean like electrolysis? That's already in use, and has been in use for a very long time.

If you meant something new that doesn't require a bunch of energy input, then yeah, that would great.

It's also a tiny part of the market, because it's literally 25x the cost of turning methane into hydrogen.

Current electrolyzers are also much less energy efficient than batteries. It's not an unsolvable problem, but battery tech is currently much more affordable than green hydrogen infrastructure. And an electrified third rail is a much better idea for trains.
