Prysmian and Rio Tinto are partnering 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 is 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 facility in Sedalia, Missouri. The project builds on an earlier collaboration announced in March 2026. Amazon Web Services is tying the initiative to its 2040 net zero target. The move is a practical example of cutting emissions at the raw material level for data centers, which are under pressure to reduce their carbon footprint. However, the scale is limited, and the full life cycle impact will depend on the electricity source for both smelting and cable manufacturing.
