Microsoft's Superconductors: The Answer to AI Power Demand?
Microsoft is investigating high-temperature superconductor (HTS) technology to understand how its data centres can support rising power requirements
TL;DR
- Microsoft is exploring high-temperature superconductor (HTS) technology for its data centers due to rising power requirements from AI workloads.
- HTS materials transmit electricity with zero resistance, cutting transmission losses and heat build-up compared to copper and aluminum.
- The technology could allow for more efficient and compact power delivery, supporting higher rack densities and AI compute.
- Superconductors may help overcome power constraints in data center design, potentially reducing the need for expanding substations or delaying growth.
- HTS systems can reduce cable size and enable direct-to-rack power delivery, as demonstrated by a 3MW cable connected to a rack prototype.
- Beyond data centers, superconducting lines can reduce strain on surrounding grid infrastructure and minimize voltage drop.
- Companies like VEIR and American Superconductor Corporation are developing solutions utilizing superconductor technology for power delivery and grid resilience.
