- WAVE-ENERGIZED DIODE PUMP

Resumen de: US2024151204A1

An apparatus that floats at the surface of a body of water over which waves pass, causing a nominally vertical axis of the apparatus to tilt away from an axis normal to the resting surface of the body of water. Tilting allows a fluid to flow through a channel that in an un-tilted apparatus would require the gravitational potential energy of the fluid to increase (i.e., to flow uphill), but, because of the tilt allows the fluid to flow through the channel in a downhill direction. Successive wave-driven tilts of the apparatus incrementally raise water to a head from which a portion of its gravitational potential energy can be converted to electrical power by causing the water to return to a lower level by flowing through a water turbine, or through some other apparatus that performs a useful function when supplied with a flow of high-pressure water.

HYDROGEN PRODUCTION AND CONVEYANCE SYSTEM AND METHOD

Resumen de: US2025179985A1

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.
