The Hydrogen Fuel Well extracts Hydrogen from seawater or fresh water using electrolysis.

Cylinders (the cells in the diagram) contain and pressurize Hydrogen and Oxygen gases generated through electrolysis.

Reverse osmosis filters condition (desalinate / demineralize) intake water for input into the cylinders for electrolysis.

Ram turbine generators utilize the gas evolved under high pressure at water depth to generate more electrical power for electrolysis.

Electrodes pass electrical power (low voltage, high amperage current) from the ram turbine generators, and auxiliary solar arrays
    through the water to generate gases (electrolysis) under high pressure.

Electronic valves gradually release the pressurized gases from the cells, and pass them through the ram turbine generators.

Electro-chemical, solid state, final stage compression is used to maximize the Hydrogen gas pressure for metal hydride tank storage.

Power control / storage unit recieves & stores electrical power from ram turbine generators and solar arrays (not shown) for use as needed.

Water passes through the reverse osmosis filters and enters each cell as needed (water feed into cells not illustrated)

When a cell is full of water, power fed from the power control / storage unit, is automatically applied to the electrodes.

Hydrogen and Oxygen gases are generated inside the cell. About twice as much H2 is generated as O2.

As water is disassociated into gas, the gas volumes increase in the cells displacing water, and pressure builds up.

When sufficient pressure exists inside the cells, the electronic valves slowly release the gas to drive the ram turbines.

The ram turbines generate direct current (DC) power and feed it to the power control / storage unit.

Gas exiting from the ram turbines is dehumidified then drawn into electro-chemical compressors for purification,
    volume reduction and storage in metal hydride tanks / cylinders, or it could be transported by underwater
     pipeline to an on-shore distribution facility.

If tank storage is used, full tanks of Hydrogen and Oxygen are periodically gathered and delivered to an on-shore collection point.

The whole process runs automatically, unattended, so that Hydrogen and Oxygen can be generated continuously.

Collection points process the tanks for further delivery or for infusion into existing natural gas or hydrogen pipelines.

The buoyancy pressure exerted by the gases evolving in the cells is fully utilized to generate additional power for electrolysis.

Reverse Osmosis utilizes the high difference in pressure between the deeper water intake and the cell water intake to accomplish Reverse Osmosis conditioning.
