Basic laws of physics will tell you that precisely because of the extra energy you can extract from the rising bubbles, electrolysis under high pressure is going to take more energy for the same amount of water.Jackdapantyrip wrote:Electrolysis in the deep ocean. When the hydrogen and oxygen separate you have the bubbles traveling upwards to generate electricity with pressure and recombine fuel cell/burn at the surface.

"The power required for high-pressure water electrolysis, wherein water is pumped up to a high-pressure, may be less than the power required for atmospheric water electrolysis"
The pressure of the water in the ocean is already stored potential energy.

At best, you are talking about energy storage, rather than energy production. That is, you are making a battery that will store energy that is produced by other means (coal burning, nuclear, wind, solar, and so on). The question should then be how efficient it is as a battery. Personally, I doubt that your idea would work very well, and I have concerns about the pumps you linked to. The biggest problem I see is that oceans are hostile places for technology. Salt water is corrosive. Tides are troublesome. This seems like a poor environment for a battery.
Tidal power generation, on the other hand, might be efficient enough to make up for the inherent hostility of the environment. Maybe. I am less convinced about generation from deep ocean currents.

This Foxnews anchor is cringe worthy. The guy can keep his cool.
You're so vain, you probably think this sig is about you
