The DOE High-Temperature Superconductivity Program
High-Temperature Superconductivity (HTS) is a technology that has the potential to increase the efficiency of the electric power industry. Some of the possible benefits include reduction in pollution from electric generating facilities, better electric system reliability, and better power delivery systems in urban areas without new rights-of-way. The Department of Energy's efforts to advance HTS combines major national strengths:
- Entrepreneurship of the private sector
- Leading university research
- The resources of the National laboratories
The DOE engages in cost-sharing agreements with industry to allow the program to leverage funds, which maximizes research and development achievements within budget constraints. This ongoing program has offered competitive opportunities for three major program thrust areas: Second-Generation HTS Wire Development, HTS Applications, and Strategic Research.
Second-Generation (2G) HTS Wire Development – Scaling Up National Laboratory Discoveries
This part of the program is aimed at facilitating research needed for U.S. industry to scale up new processes for manufacturing superconducting wire. Innovative approaches discovered at National Laboratories are being developed into commercially viable processes by industry. This technology transfer has led to the U.S. being recognized as a leader in HTS wire development. The program’s efforts are enabling U.S. industry to manufacture long-length and high-performance wire, suitable for use in utility applications.
HTS Applications – Large-Scale Electric Systems
The program area focuses on the research, development, and testing of prototype HTS power system applications through teaming arrangements with government and industry. Research teams investigate adaptability issues for using superconducting wire in power system applications such as transmission cables and fault-current limiters. The HTS application projects are demonstrating devices that can improve reliability and strengthen the electric system.
Strategic Research – Solving Fundamental Problems
This program element provides the underlying knowledge base needed for the success of the industry-led projects. Strategic research is led by the national laboratories with close collaboration with academia and focuses on research to address fundamental technological issues that will result in a better understanding of the relationship between HTS materials microstructure and their ability to carry currents over long lengths. Strategic Research includes efforts in basic materials processing, systems and benefits analysis, and cryogenic systems.
