High temperature superconductivity (HTS) is the elimination of Ohmic resistance to the flow of electric current at temperatures significantly higher than in conventional metallic superconductors, and even above the boiling point of liquid nitrogen (77 Kelvin). HTS wire has application wherever large currents are to be transported efficiently, or wherever high magnetic fields are to be created in a compact way.

The application of the high temperature superconductors is broadly regarded as one of the key technologies of the 21st century. HTS wire enables energy-efficient electrical machinery that use far less energy and creates more powerful magnetic fields than larger, heavier magnets that use conventional materials, such as copper.

Opportunities to use the new technology are seen in almost all equipment areas of the electric energy technology. Volume and weight savings of up to 65 percent are expected through these new materials.
