Title:
LIQUEFIED HYDROGEN SUPPLY SYSTEM AND METHOD
Document Type and Number:
WIPO Patent Application WO/2024/029653
Kind Code:
A1
Abstract:
The present invention relates to a liquefied hydrogen supply system and method, which are capable of controlling the generated amount of boil-off gas of liquefied hydrogen and maintaining a low pressure in a liquefied hydrogen storage tank that is applicable to storage equipment for storing a large amount of hydrogen in a liquefied state or to a transportation means for storing and transporting liquefied hydrogen. The liquefied hydrogen supply system according to the present invention comprises: a plurality of liquefied hydrogen storage tanks which store liquefied hydrogen, and which have temperature control devices for controlling internal temperature in order to maintain low internal pressure; a plurality of pressure tanks which receive, from the liquefied hydrogen storage tanks, the liquefied hydrogen to be supplied to a place requiring liquefied hydrogen and store same, and which are maintained at a high pressure while having a capacity smaller than that of the liquefied hydrogen storage tank; and a liquefied hydrogen supply line, which is a flow path through which the liquefied hydrogen is transferred from the pressure tanks to the place requiring liquefied hydrogen, wherein the temperature control device includes: a densification unit for maintaining at least a portion of the stored liquefied hydrogen at a first temperature, which is the densification temperature; and a temperature-maintaining unit for maintaining at least a portion of the stored liquefied hydrogen at a second temperature, which is higher than the first temperature, and further includes a compressor for compressing hydrogen boil-off gas generated in the liquefied hydrogen storage tanks, and supplying compressed gas to the pressure tanks so that delivery pressure for supplying the liquefied hydrogen from the pressure tanks to the place requiring liquefied hydrogen is formed.
