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.
