SMES: New Energy Storing Technology by ABB Using Electromagnetic Fields and Superconductivity

ABB, a Swiss-based engineering company, has presented a prototype of their innovative superconducting magnetic energy storage (SMES), at a DOE ARPA-E conference which took place in Washigton D.C. at the beginning of this month. Their 3.3 kWh proof-of-concept SMES is not very cost-effective for the moment, but may one day provide cleaner storage solutions for excess alternative energy.

Scientists Discover Nano-Scale Superconducting Material

Researchers from the Bar-Ilan University in Israel, collaborating with the Brookhaven National Laboratory in the U.S. have designed superconducting thin films patterned with large arrays of nanowires and loops. The temperature at which they superconduct is pretty low and hard to get for the moment – only 30 °K (-243°C). Magnetic fields have proved themselves to change the material’s electrical resistance in an unexpected manner.
