Here, we report a direct coupled, proof-of-concept electrochemical system that uses a bipolar membrane electrodialysis (BPMED) cell and a vapor-fed CO<sub>2<\/sub> reduction (CO<sub>2<\/sub>R) cell to capture and convert CO<sub>2<\/sub> from oceanwater. The BPMED cell replaces the commonly used water-splitting reaction with one-electron, reversible redox couples at the electrodes and demonstrates the ability to capture CO<sub>2<\/sub> at an electrochemical energy consumption of 155.4 kJ mol<sup>-1<\/sup> or 0.98 kWh kg<sup>-1<\/sup> of CO<sub>2<\/sub> and a CO<sub>2<\/sub> capture efficiency of 71%. The direct coupled, vapor-fed CO<sub>2<\/sub>R cell yields a total Faradaic efficiency of up to 95% for electrochemical CO<sub>2<\/sub> reduction to CO. The proof-of-concept system provides a unique technological pathway for CO<sub>2<\/sub> capture and conversion from oceanwater with only electrochemical processes.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>DOI: 10.1038\/s41467-020-18232-y Authors: Ibadillah A.
