Superconducting Magnetic Energy Storage (SMES)

Overview | SMES Project
Superconducting Magnetic Energy Storage (SMES) is a novel technology that stores electricity from the grid within the magnetic field of a coil comprised of superconducting wire with near-zero loss of energy.
SMES is a grid-enabling device that stores and discharges large quantities of power almost instantaneously. The system is capable of releasing high levels of power within a fraction of a cycle to replace a sudden loss or dip in line power. Strategic injection of brief bursts of power can play a crucial role in maintaining grid reliability especially with today’s increasingly congested power lines and the high penetration of renewable energy sources, such as wind and solar.
A typical SMES consists of two parts – cryogenically cooled superconducting coil and power conditioning system – which are motionless and result in higher reliability than many other power storage devices. Ideally, once the superconducting coil is charged, the current will not decay and the magnetic energy can be stored indefinitely.
Benefits of SMES
2010 Superconducting Magnetic Energy Storage (SMES) Project
SuperPower Inc., in partnership with ABB Inc., Brookhaven National Laboratory (BNL) and the Texas Center for Superconductivity (TcSUH) at the University of Houston are developing and will build an advanced SMES device. This project is funded in part by an award from the Advanced Research Projects Agency-Energy (ARPA-E).
Program Duration: 36 Months (2011-2013)
SMES Demonstrator specifications:
... the mark of excellence
ARPA-E is modeled after the successful Defense Advanced Research Projects Agency (DARPA) Agency within DOD, and provides R&D funding for transformational new energy technologies and systems
