Does this make any applications commercially viable now?
Not yet — 151K is a record, but it still requires liquid nitrogen cooling, the same infrastructure commercial superconductors already use, and the pressure-quench manufacturing method has no proven path to industrial scale.
Why it matters: The real unlock for truly new applications is room-temperature superconductivity, which remains roughly 122°C away.
- Liquid nitrogen cools to 77K, well below 151K — so this material works with existing cooling infrastructure, but so does YBCO (93K), which has been commercial since the 1990s in MRI machines, fusion magnets, and power cables.
- The pressure-quench technique uses diamond anvil cells — lab instruments that work on tiny samples. Scaling that process to produce bulk wire or tape is an unsolved manufacturing problem.
- Mercury cuprates are brittle ceramics that can't easily be drawn into wires, the standard form for grid and magnet applications — the same fabrication wall that blocked the 133K material set in 1993.
- Companies like Veir (HTS power cables) and Microsoft (HTS for data center cooling) are already pursuing commercialization based on existing 77K-class materials, not waiting for higher Tc records.
Room for disagreement
- Chu's camp argues the pressure-quench method is a genuine technique shift — not just a higher number — because it shows a new way to stabilize high-pressure phases at ambient conditions, potentially applicable to other material families, which could eventually yield something more manufacturable. Critics, including coverage at Tom's Hardware, counter that 151K is scientifically interesting but practically incremental: the cooling infrastructure and fabrication problems are identical to what blocked the 1993 record, and the distance to room temperature dwarfs the 18-degree gain.
