Prysmian and Rio Tinto have partnered to supply electrical cables made with low-carbon aluminum for an Amazon data center in Ohio. The aluminum is produced using ELYSIS inert-anode technology, which eliminates direct greenhouse gas emissions from the smelting process and releases pure oxygen instead. This marks the first known use of inert-anode-smelted aluminum in a data center, according to the companies. The cables will be manufactured at Prysmian's Sedalia, Missouri facility. The project builds on a collaboration announced in March 2026 and aligns with Amazon Web Services' goal of reaching net zero carbon emissions by 2040. By using low-carbon aluminum at the raw material level, the companies say the carbon footprint of data centers can be reduced significantly. This initiative highlights a practical step toward decarbonizing the materials used in digital infrastructure, potentially setting a precedent for other large-scale data center operators to follow.
