Electrochemical transformation of carbon dioxide (CO ₂ ) to hydrocarbon fuels such as methane (CH ₄ ), offers a promising solution for long-term and large-capacity storage of renewable electricity. To enable this technology, the conversion of CO ₂ on CH ₄ achieve high selectivity and energy efficiency at high currents. Here we present an electrochemical conversion system that incorporates proton-bicarbonate-CO2 mass transport control _connected with an in-situ copper (Cu) activation strategy to achieve high CH4 selectivity _at high currents.
