SYSTEM FOR COLD HEAT TRANSFER AND HYDROGEN LIQUEFACTION USING COLD HEAT CIRCULATION OF LIGUIFIED HYDROGEN

摘要

The present invention relates to a hydrogen liquefaction and cold heat transfer system using liquid hydrogen cold heat circulation, and a hydrogen circulation method using the same. Specifically, according to an embodiment of the present invention, a liquid hydrogen production module for cooling and liquefying gaseous hydrogen; And a gaseous hydrogen supply module generating gaseous hydrogen by exchanging liquid hydrogen with air, and generating liquid air by expanding the air exchanged with liquid hydrogen, wherein the liquid hydrogen production module is generated in the gaseous hydrogen supply module. A hydrogen liquefaction and cold heat transfer system using liquid hydrogen cold heat circulation may be provided in which hydrogen is precooled using liquid air.
