Superconducting Energy Storage Technology: A New Possibility

Tim Coombs Magnifye Manager, Department of Engineering, University of Cambridge

Let me talk about the stock of SMES superconductor energy. SMES is a DC magnetic field-based energy storage system that stores electricity in a DC magnetic field. It is unique and can store electricity as soon as it comes in. There is no need to convert electricity to chemical energy, to compressed air, or to pump energy in the mountains.

SMES systems include superconducting magnet coils, power conversion systems, cryogenic systems and control units. One of the most expensive is the power conditioning system, when the price of some of these components declines, the superconductor will become economically viable and the decline in the price of superconductor magnets will also help to promote the popularity of superconductors. Superconductor power transmission without loss, is a high-density power storage. In practical applications, SMES can reduce low-frequency oscillation, improve transmission capacity, improve voltage stability. In terms of power quality, SMES systems provide energy for flexible AC power transmission. At the same time, in distributed generation, SMES can smooth the power output of distributed power generation system and improve power generation efficiency.

Currently, SMES's high-performance energy storage features enable it to store backup power to increase generator power and system reliability, provide uninterrupted power to sensitive loads or critical equipment, and support in the paper industry, automotive assembly, petrochemical refining, chemical And the pharmaceutical field has a very wide range of applications.

This technology is excellent but still faces some real challenges. Such as the need to cool the coil to maintain the operating temperature, the material needs to be improved.
