Applied Superconductivity

The applied superconductivity research (past funded by DOE Office of Electricity Delivery and Energy Reliability) is related to modernization of the U.S. power grid. One direction of the modernization is replacement of normal metal (copper, aluminum) transmission lines with High Temperature Superconducting (HTS) cables. Our group concentrates its effort on studying fundamental thermodynamics of nucleation and texture development of thick YBCO layers. High-performance YBCO layer is a critical element of modern second generation (2G) HTS wire.

Major features of HTS power cables are:

• Up to 10 times more power capacity supports new generation and load growth
• High power capacity at lower voltage enables easier siting and reduced ancillary systems costs
• Ideal solution for breaking urban power bottlenecks
• Improved cost-effective control of power flow across meshed grids
• Extends the operating life of existing high-load corridor

On-going research projects:

• Nucleation efficiency of industrial oxide buffers
• Isotropic HTS materials
• Third generation (3G) wire development

History of Applied Superconductivity research at BNL:

• Low-temperature superconducting wire research 1970-1986
• First generation (1G) Bi-Sr-Ca-Cu-O HTS wire development 1986-2000
• Second generation (2G) Y-Ba-Cu-O HTS coated conductor development 1997-present

One of ten national laboratories overseen and primarily funded by the Office of Science of the U.S. Department of Energy (DOE), Brookhaven National Laboratory conducts research in the physical, biomedical, and environmental sciences, as well as in energy technologies and national security. Brookhaven Lab also builds and operates major scientific facilities available to university, industry and government researchers. Brookhaven is operated and managed for DOE's Office of Science by Brookhaven Science Associates, a limited-liability company founded by the Research Foundation for the State University of New York on behalf of Stony Brook University, the largest academic user of Laboratory facilities, and Battelle, a nonprofit, applied science and technology organization.
