SEAWATER NON-DESALINATION IN-SITU DIRECT ELECTROLYSIS HYDROGEN PRODUCTION METHOD, APPARATUS, AND SYSTEM

Resumen de: US2025171910A1

This invention discloses a method, device, and system for the direct electrolysis of seawater without desalination for hydrogen production. By immersing the direct electrolysis device for hydrogen production from seawater without desalination directly into seawater, driven by the pressure difference at the interface between seawater and the self-driven electrolyte, seawater continuously enters the device through the solution mass transfer layer. The self-driven electrolyte induces the water to enter the electrolyte solution, while the hydrophobic action of the solution mass transfer layer effectively blocks non-water impurities in the solution. During electrolysis, the water in the self-driven electrolyte is consumed to produce hydrogen and oxygen, inducing the regeneration of the electrolyte, maintaining the pressure difference at the interface, and achieving a self-circulating excitation drive without additional energy consumption.

Resumen de: US2025171915A1

A method by which an environmental energy (e.g., wave energy) is harvested, converted into electrical power, and thereafter used to electrolyze seawater into hydrogen and chlorine gases. Those gases are recombined into hydrogen chloride from which is formed hydrochloric acid solution which is diluted and deposited at a depth sufficient to ensure its neutralization and sequestration for a significant period of time (e.g., for over a millennium). By removing chloride ions from a portion of the sea adjacent to its upper surface and depositing them into a portion of the sea more adjacent to its bottom, acidity is shifted from the surface to base of the sea, and the surface ocean is given a greater ability to absorb and buffer atmospheric carbon dioxide without a corresponding increase in acidity.
