The present invention is directed to methods to sequester oxides of carbon to prevent them from entering the atmosphere as gases. More specifically, this invention is directed to methods of chemical reactions and process to decompose carbon oxides by combustion of a metal fuel with carbon oxides using a regeneration process to recover the metal fuel. The process can optionally and beneficially be coupled to other useful chemical processes for the industrial purpose of sequestering carbon oxides into useful commercial chemicals and elements like carbon, chlorine, and sodium bicarbonate.
