Abstract: A method for converting carbon dioxide in a gaseous environment, including air into useful materials by use of renewable energy sources which comprises: (1) extracting carbon dioxide from a gaseous source using a sorbent such as sodium hydroxide, calcium hydroxide, or potassium hydroxide; (2) utilizing wind power, solar power, or other renewable energy sources to regenerate said sorbent by membrane cell electrolysis or other similar method, simultaneously producing hydrogen (H2) gas; (3) releasing carbon dioxide from said sorbent; and (4) utilizing the Fischer Tropsch process, Mobil process, ICI process, or related or similar processes to convert carbon oxides to a hydrocarbon concomittantly with or after effecting the reverse water-gas shift reaction to convert said CO2 and H2 gas into carbon monoxide for reaction in said Fischer Tropsch process, Mobil process or ICI process.
