An alternative approach is electrochemical direct carbon capture (EDCC), which allows for the capture of CO2 from diluted sources such as direct air capture (DAC) or direct ocean capture (DOC), ultimately resulting in net-zero carbon emissions. In this review, the authors discuss recent advancements in EDCC technology and their potential for future applications, especially using organic active materials. They provide an overview of the fundamentals of EDCC and practical strategies for demonstrating an EDCC system, including molecular design, electrolyte selection, and device configuration. The authors also delve into design strategies for potential redox-active organic sorbents, with a particular emphasis on understanding currently utilized material candidates from other electrochemical applications and density functional theory (DFT) calculation-guided material selection in the design principle of EDCC.
