Abstract
The present disclosure is a method and system for the reduction of carbon dioxide. The method may include receiving hydrogen gas at an anolyte region of an electrochemical cell including an anode, the anode including a gas diffusion electrode, receiving an anolyte feed at an anolyte region of the electrochemical cell, and receiving a catholyte feed including carbon dioxide and an alkali metal bicarbonate at a catholyte region of the electrochemical cell including a cathode. The method may include applying an electrical potential between the anode and cathode sufficient to reduce the carbon dioxide to at least one reduction product.
Claims9
A method for reducing carbon dioxide comprising:
- receiving a feed of hydrogen gas at an anolyte region of an electrochemical cell including an anode, the anode including a gas diffusion electrode;
- and further receiving an anolyte feed, comprising an anolyte solution, at the anolyte region of the electrochemical cell;
- receiving a catholyte feed including carbon dioxide and an alkali metal bicarbonate at a catholyte region of the electrochemical cell including a cathode, comprising receiving a feed of carbon dioxide gas at the catholyte region of the electrochemical cell including the cathode, and further comprising receiving a catholyte solution at the catholyte region of the electrochemical cell, the cathode including a gas diffusion electrode, wherein the cathode gas diffusion electrode comprises a catalyst for the reduction of carbon dioxide, deposited on a support, in a three-dimensional structure, the cathode gas diffusion electrode including a hydrophobic binder and/or filler between the structure and a membrane;
- and
- applying an electrical potential between the anode and the cathode of the electrochemical cell sufficient to reduce the carbon dioxide to a reduction product.
