Abstract

A system for a multi-chambered electrochemical cell for carbon dioxide removal includes an electrochemical cell. The electrochemical cell includes an anodic chamber at a first end of the electrochemical cell, which includes an anode. The electrochemical cell includes an acid swing chamber adjacent to the anodic chamber and separated by a cation exchange membrane. The electrochemical cell includes a desalination chamber separated from the acid swing chamber by a anion exchange membrane. The electrochemical cell includes a base swing chamber in fluid communication with the acid swing chamber and the desalination chamber. The base swing chamber is adjacent to the desalination chamber and separated by a cation exchange membrane. The electrochemical cell includes a cathodic chamber at a second end of the electrochemical cell, the cathodic chamber comprising a cathode, wherein the cathodic chamber is adjacent to the base swing chamber and separated by a second anion exchange membrane.
