TECHNOLOGY FOCUS - ELECTRICAL POWER AND ENERGY - Preferred Component: The renewable energy source is a fuel cell powered by renewable hydrogen, a synthetic fuel, biomass, or biofuel; or wind turbine, solar cell, hydroelectric generator, biofuel, geothermal, or oceanic. Preferred Condition: The electricity supplied from the source is 1.2-10, preferably 1.2 V. A pH of the base produced at the cathode region ranges is 8-14.    TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Method: The method further comprises isolating bicarbonate or carbonate from the solution. Isolating bicarbonate or carbonate from the solution comprises precipitating bicarbonate or carbonate from the solution. The method further comprises chilling the solution to 0-10 degrees C to precipitate carbonate or bicarbonate from the solution. The method further comprises adding a salt comprising calcium ions to isolate calcium carbonate from the solution or adding a salt comprising magnesium ions to isolate magnesium carbonate from the solution. It further comprises spraying the solution to precipitate carbonate or bicarbonate from the solution. The method further comprises contacting the acid produced at the anode region with the gaseous carbon dioxide in an electrochemical cell to produce reduced carbon compounds of formula CmHxO2n. It further comprises chemically reducing carbon dioxide by reacting hydrogen gas produced by the system with carbon dioxide trapped by the system to produce carbon monoxide, a precursor for other synthetic processes. The acid produced at the anode region is contacted with a mineral compound to form a carbon dioxide sequestering material.m=1-6;x=0-24; andn=0-6.Preferred Condition: A pH difference between the anode region and the cathode region of greater than or equal to 6 is maintained. Preferred Component: The source of gaseous carbon dioxide is atmospheric carbon dioxide or gas stream. The aqueous electrolyte comprises alkali salt free of chloride ions or sodium salt free of chloride ions. It is calcium sulfate, magnesium sulfate, sodium nitrate, potassium nitrate, sodium bicarbonate, sodium carbonate, potassium bicarbonate, potassium carbonate, calcium carbonate, or magnesium carbonate, preferably sodium sulfate or potassium sulfate. The mineral compound is talc, clay mineral sepiolite, clay minerals, serpentine, asbestos, or mining byproducts.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Compound: The reduced carbon compound is formic acid, oxalic acid, formaldehyde, or methanol.
