Superconducting Magnetic Energy Storage device size

Click For Summary

Discussion Overview

The discussion centers on the size and operational characteristics of a superconducting magnetic energy storage (SMES) device capable of storing 100 kilowatt-hours of energy. Participants explore the implications of using high-temperature superconducting materials, such as YBCO, and the associated cryogen consumption.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant inquires about the size of a SMES device that could safely carry 100 kilowatt-hours of energy and the cryogen consumption if made from high-temperature superconductors.
  • Another participant notes that 100 kWh is equivalent to 360 MJ and mentions that existing magnets capable of storing this amount of energy are quite large, measuring several meters in height and length.
  • A later reply asks for specific examples of such large magnets.
  • Another participant references the CMS magnet as an example of a large magnet.
  • One participant suggests looking for specifications of commercial SMES devices, noting that while they may not be designed for exactly 100 kWh, extrapolation could provide useful insights.

Areas of Agreement / Disagreement

Participants have not reached a consensus on the specific size or operational details of the SMES device, and multiple viewpoints regarding the size and examples of existing devices remain present.

Contextual Notes

There is a lack of detailed specifications for the energy storage devices discussed, and assumptions regarding the design and operational parameters of SMES devices are not fully explored.

How large would a superconducting magnetic energy storage device be if it were to safely carry 100 kilowatt-hours of energy? How much cryogen (liquid nitrogen) would it consume per hour if the device were made from high-temperature superconducting materials (YBCO or similar).

100 kW-hours is 360 MJ. There are magnets that can store this much energy, but they are quite large: several meters tall and long.

None, more like a hypothetical

Interesting, do you have any specific examples?
 
The CMS magnet.
 
There are commercial SMES devices, did you try to find their specifications? They won't be designed for exactly 100 kWh, but some extrapolation should not be too hard.
