Breakthrough in aluminium production using inert anode technology

Elysis has announced the successful start-up of its 450 kiloampere (kA) inert anode cell at an electrolysis plant at the Rio Tinto smelter in Alma, Québec. This step marks a decisive moment in the transition to large-scale, low-carbon aluminium production.

This industrial-scale debut marks the first implementation of inert anode technology on this commercial scale. After years of intensive research, development and rigorous testing, Elysis – a joint venture between Rio Tinto and Alcoa – has achieved a breakthrough: aluminium production at high current density without direct carbon emissions from the smelting process. According to the company, Elysis’s technology also has the potential to improve workplace safety, reduce costs and boost productivity.
