| Abstract Scope |
The global aluminium industry is trying to reduce its carbon footprint, in line with climate policy, and great strides are being made in the use of hydro, solar and geothermal electricity, as opposed to fossil-fuel powered electricity. Two major smelting challenges remain however: finding inert anodes and wettable cathodes. VSCA has invented and developed two promising solutions: 1) a nickel-based anode alloy that has been successfully tested for over a week at 960°C in a Hall cell with limited corrosion or passivation; 2) a wettable TiB2 cathode that has survived over 3 months of continuous exposure to liquid aluminium, again at 960°C, without any signs of degradation or dissolution. Combining an inert anode with a wettable cathode is considered to be the ‘holy grail’ of aluminium electrolysis. This presentation will show that green aluminium with near-zero CO2 is within grasp and could be realized with further testing and industrial scale-up. |
