To do that you first need to get a whole bunch of stuff up into space. Way more then we have managed to get into space so far. Our little space stations are not going to cut it if you want to produce industrial amounts of materials. Building all the machines you need to make a space mining operation (for example) in space is a great idea, if you have space infrastructure already in place to build highly sophisticated automated robots. But currently we can't build so much as a screwdriver in space, so we first need to get it up there.
Stop, I can only get so hard.

You could build a space escalator to get to low orbit on the moon!
Just wait until a rumor surfaces that the Chinese are attempting to build one and watch your tax dollars start whooshing out as the Repugs trumpet the need to further cut back social services so that we can get there first!

As a Brit the best we can do is probably a big trampoline on the top of a mountain at the moment!

Can't we just get Hydrogen from seawater (which there is LOTS of) through electrolysis? Why the need to dig?
The basic problem is thermodynamics. Ideally It takes X watts to electrolyze water into hydrogen and oxygen and you get X watts of power back when you run the hydrogen and oxygen through a fuel cell or you burn them.

Thanks to thermodynamics you actually spend X+Y watts to electrolyze the water due to inherent inefficiencies and you only collect X-Z watts due to losses when recombining them.

It’s fine if you want to use that process as a battery for other power generating processes like renewables but it’s not a source of energy per se.

Mining a source of relatively pure hydrogen is an energy source as the hydrogen has already been separated.

When the earth opens up under your feet, be like a seed. Fall down; wait for a white hydrogen balloon to tie to your finger and fly fly fly away.

In Scotland they can make a mountain out of a mole hill.

With people like you around they don't even have to think. Thank God when it comes to that sort of thinking they are actually preternaturally already gifted. You have to witness their behavior and make predictions. For them it happens spontaneously.

Give me a hose...I already produce an ass load of semi-pure hydrog...wait...that's probably methane...never mind.

You can, and you can pair it with off-shore wind turbines to power the electrolysis to create green hydrogen. Companies are exploring using turbines for electrolysis when energy demand drops below the amount the turbines are generating.

It seems unlikely to me that anyone is going to find large amounts of trapped hydrogen gas - at least not enough to make a sizable contribution toward replacing fossil fuels. Unless they do then it is best to consider hydrogen (like electricity) as a potentially useful form of energy - but NOT a source of energy.

I am ignorant. Considering hydrogens evasive nature I didnt even consider it a possibility that we could have natural hydrogen deposits on the planet.

edit:
Like this right?
And you're telling me we have hydrogen trapped under us by rocks and dirt? Really? Well alrighty then. I would just assumed and leftover hydrogen or whatever woulda escaped looong ago. Unless its ongoing hydrogen factories down there?

There's lots and lots of gasses that are trapped underneath the earth, that's where we get most of them from. They're remnants of ancient earth, decomposition of material over the eons, dissolution of rock and other stuff from chemical and heat breakdown, etc.

If you drill a hole straight down from just about anywhere you'll hit pockets of all kinds of stuff.
