The research area of “Electrochemical Engineering” focuses on the intensification of electrochemical reactors. Intensification makes it possible to decrease the investment costs of electrochemical processes. Given the key role of electrochemistry in the energy transition, this is essential to make the energy transition a success. For electrochemical processes, intensification implies an increase in current density without an increase in energy consumption. To make this happen we need better cell designs, better membranes, better electrode materials and operation at increased pressure and temperature.
