Document Type and Number:
Japanese Patent JP6812747
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a technique for suppressing increase in energy loss and suppressing generation of boil-off gas in a superconducting magnetic energy storage device using liquid hydrogen as a cooling medium.SOLUTION: The superconducting magnetic energy storage device 1 includes: a superconducting coil 2 for storing magnetic energy; a storage tank 4 that houses the superconducting coil 2 and stores liquid hydrogen; and orthohydrogen maintaining means 6, 7, 8 for maintaining the liquid hydrogen in a state in which an amount of orthohydrogen is high.SELECTED DRAWING: Figure 1
