Towards the Electrochemical Retention of CO2: Is it Worth it?

Electrolyzer-absorber for CO2 capture: NaOH produced cathodically by reduction of water is able to retain gaseous CO2 in a combined electrolyzer-absorber device. The process deals with two relevant environmental concerns: desalination and carbon sequestering, with only electricity and heat, which ca...

Sumario:Electrolyzer-absorber for CO2 capture: NaOH produced cathodically by reduction of water is able to retain gaseous CO2 in a combined electrolyzer-absorber device. The process deals with two relevant environmental concerns: desalination and carbon sequestering, with only electricity and heat, which can be provided using green sources. Results demonstrate that technology is feasible, obtaining removal rates of 130 mmol CO2/h at 7.5 A with coulombic efficiency in the removal of CO2 of 47.63 %.
