I don't know much about this- but I think it's done with old fashioned electrolysis from water.
Getting it out of water is no big deal as long as you have a lot of energy to do it. It could be
done with energy that would otherwise go to waste- like hydro power being made at night- which
if it's not stored will be wasted. In our area we have that pumped storage project up on a
mountain in southern Vermont- energy produced at night from other sources is used to pump the
water up the mountain for use during peak hours. So, any kind of energy source can be used to
produce hydrogen- but it will always take more to produce it then the energy in the hydrogen
which is actually sensible if that original energy would otherwise be wasted.
Like, another example, assuming nukes were OK, then at night you can't just turn the nukes off
at night- so you have it produce hydrogen which can be stored.
The real problem isn't producing it- it's how to safely use it and safely distribute it- but
those should be solvable problems. The hydrogen could be chemically converted to some other
compounds which will burn, but which are less explosive.
