Prysmian and Rio Tinto have partnered to supply electrical cables made with low-carbon aluminum for an Amazon data center in Ohio. The cables use Rio Tinto's ELYSIS inert-anode technology, which eliminates direct greenhouse gas emissions from the smelting process, releasing pure oxygen instead. This marks the first known use of inert-anode-smelted aluminum in a data center, according to Prysmian. The project demonstrates that data center carbon footprints can be reduced at the raw material level. Prysmian will manufacture the cables at its Sedalia, Missouri facility, building on a collaboration announced in March 2026. Amazon Web Services links the initiative to its 2040 net-zero target, highlighting how supply chain choices contribute to broader climate goals.
