Aluminium is an important metal. It is produced in energy intensive smelters which emit annually at least100 million tonnes of carbon dioxide (CO2) worldwide when producing some 50 million tonnes.
In September 2017 the R&D team of Arctus Metals Ltd. and Innovation Centre Iceland successfully produced the first clean aluminium metal with oxygen (O2) emission in a bench top test cell with verticalinert anodes and cathodes. This was the result of several months’ work of preparation and development, in a project supported by the Technology Development Fund of Iceland. As no carbon anodes are used there is no emission of CO2, the effluent gas is O2.
The main benefits of the game changing aluminium process are:
Multiple, vertical inert metal-alloy anodes and ceramic cathodes
- No emission of CO2 or other greenhouse gases
- O2 instead of CO2, 1 tonne O2 is generated for each tonne aluminium produced
- 20 percent less energy consumption
- 60 percent less smelter space per tonne production capacity
- 40 percent less capital investment per tonne production capacity
- Better aluminium quality (99.9 percent vs 99.7 percent)
The R&D development team is now preparing scale up for runs at 1,000 Amp in a cell with larger multi plevertical inert anodes and cathodes. Arctus estimates to have a full scale commercial cell running at 100,000 Amp in year 2022 and then prototype plats of few cells in operation in cooperation with Icelandic and European aluminium smelters.
