I Superconducting Magnetic Energy Storage device size

  1. Apr 6, 2016 #1
    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).

    Is this a school project or homework?

    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?

    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.
