Patent ID: 7727374

Claim:
A method of sequestering carbon dioxide produced by a source and contained in a gas stream, comprising the steps of: (a) obtaining a hydroxide in an aqueous mixture; (b) admixing the hydroxide with carbon dioxide produced by the source to produce bicarbonate products or a combination of carbonate and bicarbonate products in an admixture; and (c) separating said products from the admixture, thereby sequestering the carbon dioxide in a mineral product form; wherein obtaining the hydroxide comprises: obtaining a group-1 or group-2 salt; admixing the salt with acid and water, acid and steam, or acid, water, and steam to produce a protonated brine solution; and electrolyzing the protonated brine solution to produce a hydroxide; wherein step (b) comprises altering the product equilibrium to favor the production of bicarbonate products.
