| Abstract Scope |
Carbon anodes will likely stay as the primary reduction medium in aluminium smelting for years to come, despite the ongoing development of inert anodes. This is due to the excess production of carbon coke as a by-product of hydrocarbon distillates and the CO2 profile of energy production, making inert anode likely best suited for regions with Hydropower as opposed to e.g. coal power.
This means that industry must increase the environmental performance of the Hall-Heroult process. We list several levers by which this can be done from an anode producers perspective. Levers include direct, examining factors to increase efficiency of anode production; indirect, examining factors that increase potline efficiency and fuel, examining potential to use renewable materials in anode production. We conclude that the Hall-Heroult process still has a lot of potential to reduce its carbon footprint. The paper is a combination of literary review, and several industry examples. |
