LOW-ENERGY ELECTROCHEMICAL BICARBONATE ION SOLUTION
First Claim
Patent Images
1. An electrochemical system comprising:
- an anode, a cathode and a first electrolyte disposed between the anode and cathode, wherein the system is configured to form bicarbonate ions in the first electrolyte without forming a gas at the cathode or anode on applying a voltage across the anode and cathode and contacting the first electrolyte with carbon dioxide.

Abstract
A low-energy electrochemical method and system of forming bicarbonate ion solutions in an electrochemical cell utilizing carbon dioxide in contact with an electrolyte contained between two ion exchange membranes in an electrochemical cell. On applying a low voltage across an anode and cathode in electrical contact with the ion exchange membranes, bicarbonate ions form in the electrolyte without forming a gas, e.g., chlorine or oxygen at the electrodes.
