SUMMARY

A superconducting magnetic energy storage (SMES) device designed to safely carry 100 kilowatt-hours (360 MJ) of energy would be significantly large, measuring several meters in height and length. High-temperature superconducting materials, such as YBCO, are essential for the construction of such devices. The consumption of cryogen, specifically liquid nitrogen, would be a critical factor in the operational efficiency of the SMES. Existing commercial SMES devices can provide specifications that may help in estimating the size and cryogen requirements for a device of this capacity.

PREREQUISITES
  • Understanding of superconducting materials, specifically YBCO.
  • Knowledge of energy storage concepts, particularly SMES technology.
  • Familiarity with cryogenic systems and liquid nitrogen usage.
  • Basic principles of energy measurement (kilowatt-hours and megajoules).
NEXT STEPS
  • Research specifications of existing commercial SMES devices.
  • Explore the operational principles of high-temperature superconductors like YBCO.
  • Investigate the thermal management requirements for cryogenic systems.
  • Examine case studies of large-scale energy storage solutions and their dimensions.
USEFUL FOR

Engineers, researchers, and students interested in energy storage technologies, particularly those focusing on superconducting systems and their practical applications in energy management.

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.
