摘要：

We discuss our experimental progress toward energy-efficient electrochemical CO(2) capture from the atmosphere. First we discuss the latest results from an ongoing project that uses a modified-fuel-cell-based approach for CO(2) concentration [1]. Using this approach, we have demonstrated CO(2) capture from atmospheric concentrations with an energy consumption of less than 400 kJ/mol(CO(2)). We also discuss progress on a second approach to electrochemical CO(2) concentration: a novel pH-controlled, high pressure electrodialysis system that allows energy-efficient, high-rate CO(2) separation from the atmosphere [2].
