Rio Tinto to Revolutionize Aluminum Production with Carbon-Free Elysis Technology in Quebec, Canada

The Arvida smelting complex of Rio Tinto in Quebec, Canada is set to adopt new Elysis carbon-free technology in an effort to transition to more environmentally friendly production methods. The pilot plant, equipped with Elysis technology, will be designed and built at the Arvida complex. Unlike conventional electrolysis chambers that separate aluminum and oxygen compounds with a carbon anode, Elysis technology uses an inert anode, eliminating the carbon component entirely. By removing carbon from the process, the separation of aluminum from oxygen results in the emission of oxygen only.

This innovative technology aims to replace traditional aluminum production methods and significantly reduce greenhouse gas emissions associated with the production of everyday goods like consumer products, construction materials, transportation components, and electricity industry products. In Canada alone, this new technology could potentially reduce approximately 7 million tons of greenhouse gases annually, equivalent to removing 1.8 million cars from the road and shifting to more sustainable practices.

In addition to reducing carbon emissions, Elysis technology is touted to enhance occupational health and safety, lower capital and operating costs, and boost productivity levels. This new technology has the flexibility to be retrofitted onto existing as well as new smelting facilities. Rio Tinto anticipates the pilot plant to begin operations in 2027
