Microsoft explores superconductors for AI data centres
Cryogenic cooling remains key challenge for superconductors.
Microsoft is studying high-temperature superconductors to transmit electricity to its AI data centres in the US. The company says zero-resistance cables could reduce power losses and eliminate heat generated during transmission.
High-temperature superconductors can carry large currents through compact cables, potentially cutting space requirements for substations and overhead lines. Microsoft argues that denser infrastructure could support expanding AI workloads across the US.
The main obstacle is cooling, as superconducting materials must operate at extremely low temperatures using cryogenic systems. Even high-temperature variants require conditions near minus 200 degrees Celsius.
Rising electricity demand from AI systems has strained grids in the US, prompting political scrutiny and industry pledges to fund infrastructure upgrades. Microsoft says efficiency gains could ease pressure while it develops additional power solutions.
