  1. Superconductivity Power in the Fast Lane Paul M. Grant Board of Directors Electric Power Research Institute 15 April 1997 Washington

  2. MRI Surgical Unit General Electric Tevatron Fermi National Laboratory Superconductivity…What’s It Good For?

  3. Superconductivity…What’s In It For Me? • How do you make an underground cable work like a transmission line? • How do you make a 13 kV line behave like 69 kV (no transformers!)? • How do you wheel power 1000 miles?

  4. • e- Models of Electrical Conductivity Resistance  Temperature 

  5. A Big Surprise! Thus the mercury at 4.2 K has entered a new state, which, owing to its particular electrical properties, can be called the state of superconductivity H. Kamerlingh-Onnes (1911)

  6. • e- + + + + • e- Physics of Superconductivity Electrons Pair Off! R TC T

  7. J. G. Bednorz and K. A. Mueller IBM Zuerich, 1986 Another Big Surprise!

  8. 1900 1920 1940 1960 1980 2000 Transition Temperatures:TC vs. Year 200 164 K 150 Temperature, TC (K) 100 High-TC 50 Low-TC 0 Year

  9. Power Applications:Wires to Cables 2 Performance/Cost by 2003

  10. 1997: Utility Cable Studies Begin Philadelphia Electric Company (PECO) Downtown Philly Concrete Ducts: 13 kV, 2 Miles 100 % Use Study Complete: 5/97

  11. 1997: Utility Cable Studies Begin South Carolina Electric & Gas (SCEG) Upscale Urban Neighborhood Underground link: 115 kV, 1.3 Miles Only 5% Use Study Complete: 4/97

  12. Asia: The Energy Future Location of Asian Gas Fields and Major Energy Use Centers

  13. North America:Continental Electric Power • Two Wheeling Scenarios: • Hudson Bay Hydo Power into New England/New York • Vera Cruz Gas Fields to Texas

  14. The Electricity Option:“Edison Project” • Total Cryopower System • Power Capacity: 5 GW dc • Cost: < Gas Pipe & HVDC, • > 500 Miles

  15. Superconductivity…The Take-Home Message • Already represents a quantum improvement in applications of electricity • Undergoing rapid development for improved power delivery and quality • Will provide a key enabling technology for the 21st Century Electricity Enterprise
