Abstract Electrochemical CO 2 reduction (denoted as ECO R) technology is expected to transform greenhouse gas into a range of fuels and chemicals combined with renewable electricity. A wide fundamental research has been dedicated the clarification reaction mechanisms developing catalyst materials, which have significantly facilitated level R technology. Nevertheless, still encounters limitations such low utilization efficiency insufficient selectivity high‐value products. Addressing these challenges crucial for be implemented in practical applications. In an electrolysis system, electrolyzer represents core component system primary site. Therefore, composition structure will directly affect performance. This review begins by outlining recent progress at large‐scale level, followed comprehensive analysis industrial configuration, including detailed considerations electrode, diffusion layer, membrane electrolyzer. Finally, we elucidate remaining associated industrialization this offer suggestions advancing it.
