Microsoft Partners with Veir to Develop High-Temperature Superconducting Technology for Data Centers
Microsoft is investing in high-temperature superconducting (HTS) technology through a partnership with Veir to enhance energy efficiency in future data centers. HTS cables can transmit electricity with near-zero resistance, utilizing liquid nitrogen cooling to eliminate energy loss, unlike traditional copper or aluminum conductors. Veir demonstrated the technology in November 2025, successfully delivering three megawatts through a single cable. The technology aims for commercialization by 2026, but challenges such as high material costs and cooling issues persist.

Microsoft is collaborating with Veir to advance high-temperature superconducting (HTS) technology for future data centers, focusing on improving energy efficiency and reducing transmission losses. HTS cables, which use liquid nitrogen for cooling, can carry electricity with nearly zero resistance, eliminating energy loss and generating no heat.
Veir's demo in November 2025 achieved three megawatts through one cable, compared to 150-200 kilowatts heat loss from traditional conductors. While this demo marks a technical milestone, it is limited in scope and does not reflect real-world operations. Veir aims for commercialization of the technology in 2026, but Microsoft has no timeline for deployment due to high material costs and cooling challenges.
