TECHNOLOGY FOCUS - CHEMICAL ENGINEERING - Preferred Method: In producing hydrogen, the constituent gases include carbon, sulfur and nitrogen from the gases carbon dioxide, sulfur dioxide, nitrogen monoxide or nitrogen dioxide. The method comprises generating electricity and, further preferably, generating electricity from the heat of the furnace and, more preferably, from steam generated by the furnace. The furnace uses burning a hydrocarbon based fuel as a heat source, where the hydrocarbon based fuel is a fossil fuel or a biofuel. The brine is produced at a concentration of 20-30% by weight of salt, and further preferably, 25%. The furnace flue gas and/or third party flue gases are cooled in a closed circuit cooling tower. Applying the furnace flue gas and/or third party flue gases to the sodium hydroxide solution takes place between 70-80 degrees C, preferably at 75 degrees C. The heat from the cooling tower and heat from the exothermic reactions caused by applying the furnace flue gas and/or third party flue gases to the sodium hydroxide solution is used to heat sea water prior to the sea water bring distilled. The furnace flue gas and/or third party flue gases are aerated under pressure through the sodium hydroxide solution. Also, the furnace flue gas and/or third party flue gases is applied to the first of a set of vats connected in series, un-reacted flue gases from an earlier vat being passed to a later vat and sodium hydroxide solution is applied to the last of the vats in the series and travels through the vats in the opposite direction to the flue gases, where there are at least three vats connected in series. The hydrochloric acid is formed using desalinated water from the electrolysis of steam. Storing carbon dioxide further comprises coating the glass foam with a layer of glass, where the layer of glass is a layer of malleable glass rather than molten glass. The glass foam is formed into spheres by a forming apparatus, and where the layer of glass is formed around the spheres of glass foam. The method is performed under pressure, preferably at a pressure of around 150 Bar. The carbon dioxide is compressed between 150 and 200 Bar, ideally 175 Bar. Preferred System: The system includes a coating apparatus for coating the glass foam with a layer of glass; and a forming apparatus which forms the glass foam into spheres. The layer of glass is formed around the spheres of glass foam.
