SUBMERGED GAS CONVEYANCE OF CONSTANT PRESSURE AND BUOYANCY

Resumen de: WO2024145305A1

Disclosed is an apparatus, system, and method, by which a gaseous chemical, e.g., hydrogen gas, can be retrieved by, stored within, and transported by, a low-cost autonomous vessel. The vessel is deployed, and operates, within a body of water. A submerged portion of the vessel is subjected to an ambient hydrostatic pressure that is used to compress the stored gases. A spar buoy that floats adjacent to a surface of the body of water regulates and stabilizes a depth of the submerged portion. A single pressure-tolerant chamber within the submerged portion is used to acquire gas from a gas provider and to equilibrate the pressure of the gas so acquired. The pressure-equilibrated and/or pressure-balanced gas is then drawn into a first gas storage tank through a venting of an approximately equal volume of another gas, e.g., air, from a second gas storage tank, resulting in a gas transfer at an approximately constant pressure.

In particular, it is noted that the described system comprises a pair of split belts (1.3) where at least one capture and conversion module is fixed, wherein the capture and conversion module comprises: an articulated vane (10) composed of a shovel (1) and a rigid rod (1.1), a motion conversion unit (20), an electric generator (3), a protective housing (5), a metal chassis (1.2) for fixing at least one capture and conversion module; and an electric accumulator module (40) connected to the at least one capture and conversion module, wherein the electric accumulator module comprises: a control unit (60) and one or more electric accumulators (50).

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.
