Xeus HTS wire carries current with zero resistance at liquid nitrogen temperatures, enabling efficient power transmission, fusion magnets and data-centre cooling.
Houston: 2,000 km/year. North Carolina facility starts 2026.

Yttrium barium copper oxide is deposited on metal tape using metal-organic chemical vapour deposition. The coating is a few micrometres thick.
Below its critical temperature (92 K), YBCO becomes a superconductor with zero electrical resistance. Xeus operates at 77 K (liquid nitrogen).
Because there is no resistance, current flows without heating the wire. A Xeus cable can transmit the same power as a copper cable at much lower voltage.
The cable is cooled in a cryogenic sleeve. Liquid nitrogen is affordable and abundant, much cheaper than helium.
