Mitigating emissions from point sources requires carbon-capture technologies that are efficient, scalable, and compatible with renewable electricity. This study reports a methanol-assisted electrochemical CO2 capture system based on a compact zero-gap electrolyzer, enabling flue-gas capture and direct integration with CO2 conversion. By coupling CO2 capture and utilization in one scalable platform, this work points toward lower-cost and modular flue-gas carbon management.
