The SuperPower/ORNL High-Performance Lanthanum Manganese Oxide-Enabled, High-Temperature Superconducting Tape (LMOeHTS) is a robust, high-current second-generation superconducting wire. The technology was developed by means of a Cooperative Research and Development Agreement between Oak Ridge National Laboratory (ORNL) and SuperPower, Inc., of Schenectady, New York. The Department of Energy (DOE) has funded three different Superconductivity Partnerships for Industry (SPI) projects to demonstrate the use of HTS power cables for electric transmission and distribution. The LMOe-HTS has the unique combination of strength, flexibility, throughput, and low cost needed for power-grid applications, including coils and motors. It can be fabricated at high throughput rates using reel-to-reel processes. The key to its success, as well as the key improvement from previous technology, is the development and use of an epitaxial LaMnO3 (LMO) buffer layer, which can be deposited at high rates homogenously in long lengths. The use of this buffer enables fabrication of the complete substrate for growth of superconductors at very high throughput rates. The buffer layer also enables formation of very high performance superconducting films. SuperPower licensed this technology from ORNL (via UT-Battelle, LLC, the management and operations contractor for ORNL, under contract to DOE) under an exclusive, field-of-use license agreement, for the purpose of incorporating LMO into its superconducting wires, tapes, and cables to improve performance. Sumitomo Electric Industries of Osaka, Japan, in partnership with SuperPower, has used LMOe-HTS wire to construct a 30-meter cable that was slated to be installed in the national grid in Albany, New York, in 2007. It is the world’s first second-generation HTS device. Two other demonstration projects are planned in Long Island, New York, and Columbus, Ohio. The LMOe-HTS won an R&D 100 Award in 2007.
