Superconductor Uses - 0 views

  • An idealized application for superconductors is to employ them in the transmission of commercial power to cities. However, due to the high cost and impracticality of cooling miles of superconducting wire to cryogenic temperatures, this has only happened with short "test runs". In May of 2001 some 150,000 residents of Copenhagen, Denmark, began receiving their electricity through HTS (high-temperature superconducting) material. That cable was only 30 meters long, but proved adequate for testing purposes. In the summer of 2001 Pirelli completed installation of three 400-foot HTS cables for Detroit Edison at the Frisbie Substation capable of delivering 100 million watts of power. This marked the first time commercial power has been delivered to customers of a US power utility through superconducting wire. Intermagnetics General has announced that its IGC-SuperPower subsidiary has joined with BOC and Sumitomo Electric in a $26 million project to install an underground, HTS power cable in Albany, New York, in Niagara Mohawk Power Corporation's power grid. Sumitomo Electric's DI-BSCCO cable was employed in the first in-grid power cable demonstration project sponsored by the U.S. Department of Energy and New York Energy Research & Development Authority. After connecting to the grid successfully on July 2006, the DI-BSCCO cable has been supplying the power to approximately 70,000 households without any problems. The long-term test will be completed in the 2007-2008 timeframe.

High Temperature Superconducting Magnets Just Got 45% More Power - 0 views

  • Engineers at the National High Magnetic Field Laboratory at the Florida State University are closer than ever to launching a new generation of high-field magnet, being 3,000 times stronger than an ordinary refrigerator magnet and will be able to generate a field about 45% more powerful than the strongest superconducting magnet currently available. The new high tech magnet will be made of a high-temperature superconductor that is far less expensive to operate than its conventional counterparts and more energy efficient. According to the researchers, it could mark the beginning of a new generation of super powerful magnets that help lower both the carbon footprint and cost of scientific research.

Scientists Fabricate Room Temperature Superconducting Material - 0 views

  • A new breakthrough superconducting material fabricated by a Canadian-German team has been made out of a silicon-hydrogen compound and does not require cooling. The implications of the discovery are enormous and could transform the way people live by cutting power usage from everything from refrigeration to cell phones.

EERE News: Superconducting Cable Project Points to More Efficient Grid - 0 views

  • DOE and SuperPower, Inc. commemorated on February 21 a $27 million project to install a 350-meter high-temperature superconducting (HTS) cable between two electrical substations in Albany. While that might not sound like much cable for the money, the project is the first demonstration of a technology that could someday be used to build a more energy efficient power grid. The HTS cable reduces energy loss by up to 10%, and wires using the same technology could potentially be integrated into generators, transformers, cables, and fault current limiters, making most of the equipment that produces and delivers power more energy efficient. On the other end of the power line, HTS wires can be employed in motors, providing an energy efficiency improvement for one of the largest electrical loads served by electric utilities.

The Energy Blog: Supergrid to Supply Europe with Wind Power - 0 views

  • The scheme would make the use of renewable energy, particularly wind power, so reliable and cheap that it would replace fossil fuels on an unprecedented scale, serving 1.1 billion people in 50 countries.
  • Czisch didn't comment on superconducting transmission, previous post, for some of the main lines, which are higher efficiency and more importantly can conduct up to 10 times the amount of power of today‚Äôs conventional copper cables of the same size.
  • The Independent reports that a proposed supergrid could supply Europe with carbon free electricity primarily from wind power. The 5,000-mile electrical grid, stretching from Siberia to Morocco and Egypt to Iceland, would slash Europe's CO2 emissions by a quarter, scientists say.

Superconductor market set for explosive growth? - 136 views

I just bookmarked, which appears to be one of the better information sources on superconductivity (though I've not gone in depth). At least, it gives a balanced view, avoids ext...

Superconductors: Cure for grid transmission woes? | Green Tech - CNET News - 0 views

    "The big barrier here, as with any new technology, is that electric utilities are very conservative...Now we're overcoming that obstacle with initial installations, which are relatively short runs but this superconductor pipeline is much grander in scale," he said. In practice, the cables would be placed underground, as gas pipelines are, and have nitrogen cooling stations every seven or eight miles. Fredette said the technology is feasible but would likely need some sort of loan guarantee from U.S. government to test the system in the field.
