Prysmian and Rio Tinto will supply an Amazon data center in Ohio with electrical cables made from ELYSIS low-carbon aluminum. Prysmian says this is the first known data-center use of inert-anode aluminum; the project’s value and expected revenue are undisclosed.
The cables will be made at Prysmian’s Sedalia, Missouri, facility. The companies’ relationship includes a five-year supply agreement signed in 2023 for low-carbon aluminum made using renewable hydropower from Rio Tinto’s Canadian operations, followed by a joint development agreement.
Prysmian says ELYSIS inert-anode smelting eliminates direct greenhouse-gas emissions from aluminum smelting and releases pure oxygen. In March 2026, it said ELYSIS-produced aluminum remained in development; the Amazon project demonstrates a data-center application but does not show how quickly production can scale. AWS vice president Joern Tinnemeyer linked the project to Amazon’s goal of net-zero carbon emissions across its operations by 2040. Neither company has indicated Amazon will use the cables at other data centers.
