Abstract
A system for supplying liquefied hydrogen includes: liquefied hydrogen storage tanks each comprising a temperature control unit controlling an internal temperature of the liquefied hydrogen storage tank to maintain an inside of the liquefied hydrogen storage tank at a low pressure; pressure tanks receiving and storing liquefied hydrogen to be supplied to a liquefied hydrogen demand site from the liquefied hydrogen storage tanks, the pressure tanks having a smaller capacity than the liquefied hydrogen storage tanks and maintained at a higher pressure than the liquefied hydrogen storage tanks; a liquefied hydrogen supply line through which liquefied hydrogen is transferred from the pressure tanks to the liquefied hydrogen demand site; and a compressor compressing boil-off hydrogen gas generated in the liquefied hydrogen storage tanks and supplying the compressed boil-off hydrogen gas to the pressure tanks to generate a pressure required for delivery.
