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 configured to generate gaseous hydrogen by heat-exchanging liquid hydrogen with air, and generating liquid air by expanding the air heat-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, which pre-cools hydrogen using liquid air, may be provided.
