Abstract
An alkaline production system comprising an electrochemical unit comprising a hydrogen-oxidizing anode, a cathode compartment comprising a cathode and a hydrogen delivery system configured to deliver hydrogen gas to the anode, wherein the unit is operably connected to a carbon sequestration system configured to sequester carbon dioxide with the cathode electrolyte; and methods thereof. In another embodiment, a system comprising a hydrogen-oxidizing anode in communication with a cathode electrolyte comprising bicarbonate ion; and an hydrogen delivery system configured to deliver hydrogen gas to the anode; and methods thereof.
