NOVELTY - Production of hydrogen comprises: distilling sea water by heat supplied by a furnace to produce steam and brine; electrolyzing at least a portion of the steam to produce hydrogen; electrolyzing the brine to produce hydrogen and chlorine gas and a sodium hydroxide solution; mixing at least a portion of the hydrogen gas with water to form hydrochloric acid; applying the furnace flue gas to the sodium hydroxide solution to create a sodium compounds solution; applying the sodium compounds solution to the hydrochloric acid; and separating the gases.    USE - The methods and systems are useful for producing hydrogen; and for storing carbon dioxide (claimed).    ADVANTAGE - The methods and systems are environment friendly, and efficiently and effectively store and mitigate the production of carbon dioxide through burning fossil fuels as well as to produce hydrogen as a cleaner burning fuel alternative.    DETAILED DESCRIPTION - Production of hydrogen comprises: distilling sea water by heat supplied by a furnace to produce steam and brine, the furnace also producing a furnace flue gas as a by-product which includes a set of constituent gases; electrolyzing at least a portion of the steam to produce hydrogen; electrolyzing the brine to produce hydrogen and chlorine gas and a sodium hydroxide solution; mixing at least a portion of the hydrogen gas produced from either or both of the electrolysis of the steam or brine and chlorine gas with water to form hydrochloric acid; applying the furnace flue gas and/or third party flue gases to the sodium hydroxide solution to create a sodium compounds solution of one or more of the constituent gases; applying the sodium compounds solution to the hydrochloric acid to regenerate the original gases constituent gases; and separating the gases produced when applying the sodium compounds to the hydrochloric acid. INDEPENDENT CLAIMS are:    (1) a method of storing carbon dioxide comprising: compressing the carbon dioxide; creating molten glass; applying the carbon dioxide through a set of apertures over which the molten glass is arranged such that a glass foam is created; and cooling the glass foam such that carbon dioxide is trapped within the glass foam;    (2) a hydrogen production system comprising: distillation means for distilling sea water by heat from a furnace to produce steam and brine, the furnace also producing a furnace flue gas as a by-product which includes a set of constituent gases; electrolysis means for electrolyzing at least a portion of the steam to produce hydrogen; electrolysis means for electrolyzing the brine to produce hydrogen and chlorine gas and a sodium hydroxide solution; mixing means for mixing at least a portion of the hydrogen gas produced from either or both of the electrolysis of the steam or brine and chlorine gas with water to form hydrochloric acid; a first vat enabled to receive the furnace flue gas and/or third party flue gases and the sodium hydroxide solution such that the flue gases and solution react to create a solution of sodium compounds of one or more of the constituent gases; a second vat enabled to receive the solution of sodium compounds and the hydrochloric acid to regenerate the original gases constituent gases; and gas distillation means for distilling the constituent gases produced from the reaction of the sodium compounds and the hydrochloric acid; and    (3) a carbon dioxide storage system comprising: compression means for compressing the carbon dioxide; a glass furnace for creating molten or malleable glass; gas supply means for supplying the carbon dioxide through a set of apertures over which the molten glass is supplied such that a glass foam is created; and cooling means for cooling the glass foam such that carbon dioxide is trapped within the glass foam.
