Emerging electrochemical CO2 capture and release technologies offer a solution by using redox-active sorbents and mediators to reduce energy requirements and broaden the scope for system modifications.
Global warming and climate change caused by an everincreasing accumulation of atmospheric CO2 are reaching alarming levels. In order to address this issue, significant research effort has been dedicated to the development of carbon capture processes for sequestration or utilization of CO2. Current technologies rely on energy-intensive tempera ture-or pressure-swing of CO2 sorbents, limiting the economic feasibility of the process. Herein, we review recent advances in electrochemically mediated CO2 capture and release. Specifically, redox-active sorbents and mediators provide new opportunities in separation of CO2 by significantly reducing the energy requirements and widening the scope for system modifications. In particular, strategies for electrochemically mediated regeneration of sorbents in conventional processes, direct capture and release of CO2 by exploitation of redoxactive complexes, and the outlook for electrochemically based carbon capture are covered.
