## Abstract

A system and method by which energy from ocean waves is converted into hydrogen, and that hydrogen is used to manifest electrical and mechanical energies by an energy consuming device. A portion of the generated electrical power is communicated to water electrolyzers which produce oxygen and hydrogen from water as gases. At least a portion of the generated hydrogen gas is transferred to a transportation ship via a hose-carrying, remotely operated (or otherwise unmanned) vehicle, and subsequently transferred to an energy-consuming module or infrastructure, where a portion of the hydrogen is consumed in order to manifest a generation of electrical energy, a mechanical motion, and/or a chemical reaction.

## Claims

### Claim 1

A hydrogen harvesting system, comprising:
a wave energy converter (WEC) vessel having a hydrogen tank, a submerged hull, and a hydrogen output port at said submerged hull;
a hydrogen retrieval vessel comprising a water pump and a deionized water tank; and
a navigable hydrogen transfer hose maneuvered by a hose conveyance vehicle and configured to couple to the hydrogen output port, said hose conveyance vehicle including a propulsion device;
wherein the hydrogen retrieval vessel transfers deionized water to the wave energy converter vessel and the wave energy converter vessel transfers hydrogen to the hydrogen retrieval vessel, wherein the transfer of each of the deionized water and the hydrogen occurs via the navigable hydrogen transfer hose.

### Claim 2 (depends on 1)

The hydrogen harvesting system of claim 1, wherein the navigable hydrogen transfer hose further comprises an electromagnet configured to attach to the hull at the hydrogen output port.

### Claim 3 (depends on 1)

### Claim 4 (depends on 1)

The hydrogen harvesting system of claim 1, further comprising a rotating spool adapted to retract a portion of the navigable hydrogen transfer hose.

### Claim 5 (depends on 1)

The hydrogen harvesting system of claim 1, wherein the navigable hydrogen transfer hose is operated remotely.

### Claim 6 (depends on 1)

The hydrogen harvesting system of claim 1, wherein the navigable hydrogen transfer hose is an unmanned underwater vehicle.

### Claim 7 (depends on 1)

The hydrogen harvesting system of claim 1, further comprising a hydrogen tank manifold adapted to transfer hydrogen from the navigable hydrogen transfer hose to a plurality of hydrogen tanks.
