The method described in the invention is aimed at drying moist hydrogen obtained through alkaline electrolysis, containing up to 2000 ppm of water. This is achieved through the utilization of complex processes involving water hydrolysis, hydrogen storage, and compression, employing metal hydrides. During water hydrolysis, water vapor that are present in the hydrogen gas actively reacts with a mixture of activated aluminum and NaOH, splitting into hydrogen and oxygen. Oxygen and a portion of hydrogen combine with activated aluminum to form aluminum hydroxide, while the remaining hydrogen, along with the overall hydrogen stream, enters the metal hydride container. There, upon interaction with magnesium-based powders, metal hydrides are formed, capable of preserving hydrogen from several minutes to several years without significant hydrogen loss. Using the described method, hydrogen is dehydrated from 2000 ppm of water to no more than 5 ppm of water. Dry hydrogen can successfully react with magnesium-based metals for up to 500 cycles, with absorbed/desorbed hydrogen losses not exceeding 5 %. During the decomposition of metal hydrides, the resulting hydrogen is more than 99.999 % pure and, upon release, generates pressure of up to 30 bars. The waste heat generated in industrial processes is utilized to optimize the hydrolysis and formation/decomposition processes of metal hydrides, thereby creating additional added economic and ecological value.

A direct impure water electrolysis (DIWE) approach generates green hydrogen in a modified proton-exchange membrane pure water electrolyzer (PEM-PWE), that avoids fouling, corrosion, deactivation, and side reactions normally caused by the ions in impure or saline waters. Conventional electrolyzers require ultrapure deionized (DI) water as feed because: 1) the proton-exchange membrane (PEM) and electrocatalysts are readily poisoned by the anions, e.g., chloride, and cations, e.g., sodium, calcium, and magnesium that are present in seawater or brackish water; and 2) the chloride anions readily form chlorine at the PEM-electrolyzer anode, which is toxic and corrosive. This adds substantially to the cost and complexity of the electrolyzer plant due to the water treatment plant needed for producing ultrapure DI water. The tolerance of impure water as described herein avoids reverse osmosis and deionization requirements steps which is beneficial for use in semi-arid regions with a paucity of fresh water.

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.
