Summary Prysmian and Rio Tinto will supply low-carbon aluminium cables for an Amazon Ohio data centre using ELYSIS smelting technology.
ROME (Reuters) - Italian cable maker Prysmian said on Friday it had partnered with Rio Tinto to supply electrical cables made with low-carbon aluminium for an Amazon data centre in Ohio.
The cables will use aluminium produced with ELYSIS inert-anode technology, which Prysmian said eliminates direct greenhouse gas emissions from the smelting process by releasing pure oxygen instead.
Prysmian said the project is the first known use of aluminium produced through inert-anode smelting technology in a data centre.
The company said the initiative demonstrates how the carbon footprint of data centres can be reduced at the raw-material level.
Prysmian will manufacture the cables at its facility in Sedalia, Missouri. The project builds on a collaboration between Prysmian and Rio Tinto announced in March 2026.
Amazon Web Services Vice President of Data Center Engineering Joern Tinnemeyer linked the initiative to Amazon's target of achieving net-zero carbon emissions by 2040.
