In summary, EGCs fundamentally redefine the role of electrocatalysis, shifting the paradigm from energy-intensive electrolysis toward simultaneous chemical production and net electricity generation. By unifying feedstocks valorization, green chemical synthesis and electricity generation within a platform, EGCs offer a compelling vision for future sustainable technologies. Continued advances in reaction design, catalyst development and system integration are poised to unlock scalable EGCs with high power density, high-value outputs and robust long-term stability. These developments position EGCs as a versatile and transformative platform for sustainable chemical manufacturing and energy conversion, thereby contributing meaningfully to carbon neutrality and the realization of a circular economy.
