Efficient Direct Air Capture in Industrial Cooling Towers Mediated by Electrochemical CO2 Release. | LitMetric

AI Article Synopsis

  • - The text discusses direct air capture (DAC) technology aimed at reducing climate change but highlights challenges like low efficiency, small size, and high costs due to environmental factors and the nature of CO2 capture.
  • - A new method combines DAC with industrial cooling towers, using a special buffered solution to effectively capture CO2 and an innovative electrolyzer to release it at room temperature, enhancing efficiency.
  • - This integrated system shows promise for stable operation over multiple cycles, presenting a potential breakthrough in using existing infrastructure to combat climate change more effectively.

Article Abstract

Direct air capture (DAC) is a promising technology for mitigating global climate change but suffers from low efficiency, small scale, and high cost due to the dilute atmospheric CO2, limited size of air contactors, and heat-driven CO2 release. Here, we propose combining DAC with widely used industrial cooling towers to extract CO2 from the air and using electrolysis to release the captured CO2 at room temperature. We first prepare a buffered absorbent solution consisting of sodium glycinate, glycine, and sodium chloride for effective CO2 capture from the air, solving the incompatibility problem of the cooling towers with conventional absorbents. Next, we employ a three-chamber electrolyzer for efficient release (≥95%) of the captured CO2 with high purity (≥98%) by constant current electrolysis at room temperature, bypassing the conventional energy-intensive heating process. The entire DAC system can operate stably for multiple cycles, and the mechanism for consecutive CO2 capture and release is uncovered. This work reveals the great potential of running DAC in industrial cooling towers coupled with electrochemically-driven CO2 release, opening up new avenues for curbing the increasingly severe climate change.
