Carbon capture from both stationary emitters and dilute sources is critically needed to mitigate climate change. Carbon dioxide separation methods driven by electrochemical stimuli show promise to sidestep the high-energy penalty and fossil-fuel dependency associated with the conventional pressure and temperature swings. Compared with a batch process, electrochemically mediated carbon capture (EMCC) operating in a continuous flow mode offers greater design flexibility. Therefore, this review introduces key advances in continuous flow EMCC for point source, air, and ocean carbon captures. Notably, the main challenges and future research opportunities for practical implementation of continuous flow EMCC processes are discussed from a multi-scale perspective, from molecules to electrochemical cells and finally to separation systems.
为缓解气候变化，从固定排放源和稀释源捕获碳至关重要。由电化学刺激驱动的二氧化碳分离方法有望避免与传统变压和变温相关的高能量损失以及对化石燃料的依赖。与间歇过程相比，以连续流动模式运行的电化学介导碳捕获（EMCC）具有更大的设计灵活性。因此，本综述介绍了用于点源、空气和海洋碳捕获的连续流动EMCC的关键进展。值得注意的是，从分子到电化学电池，再到分离系统的多尺度角度讨论了连续流动EMCC工艺实际应用的主要挑战和未来研究机会。
