I realized too late, that this may have been a far better forum to post this in, than the one I did. Rather than cross-post, I'll just attach a link to my other post on this forum concerning this topic:

Thank you for your indulgence.
You are right this idea has been posted here before.
Its not a bad idea.
Hmm, Are you certain?
Perhaps that was calculated based on the assumption that both gases H & O are combined in one stream, in which case that would probably be correct as the total molar weight would remain the same as water.
However I was assuming we are keeping the H and O separate as in a DC electrolysis (since the idea is to recover pure H to begin with).
Thus based on my (quick) calculation :
1 mole Hydrogen = 1 gm (22.4L at STP) density ~4.4e-5 g/ml
Avg ocean temp 1 mile down 2 deg C
Pressure 1 mile down ~2280 psi (155 atm)
V=(nRT)/P
1 mole @ 2280psi and 2C = 145 ml (cc)
density H @ 1 mile deep = 1gr/145cc = .007g/ml (assuming I got all the decimal places correct - someone double-check my math) vs. ~ 1.03gr/ml for salt water. (seawater actually gets slightly denser at 1 mile depths too)
Thus it should rise readily (and decrease in density - increase in volume as it goes)
I haven't done the math, but even the Oxygen component should be light enough sufficient to rise.
Whether 1 mile is sufficient for break even = ?
Even if it generates enough to merely reduce the cost of H production there may be an advantage.
Good job Mike,
Sorry for my daum response.

What is the maximum pressure electrolysis of water can occur?
Does it take more electricity at high pressure?
