SGL Group – The Carbon Company, a leading manufacturer of carbon-based products, and Hydro, a leading aluminum producer, launched a three-year project aiming to tap further energy-saving potentials in the primary aluminum production process. The companies will join forces to develop a new cathodic solution for this purpose. Using novel materials and a new electrolysis cell design, the solution will enable a significant reduction of the anode-cathode distance, one of the main drivers of energy consumption. If proven successful, the new cathode technology may lead to substantial energy savings in primary aluminum production.
