HYDROGEN STORAGE SYSTEM OF ULTRA LOW TEMPERATURE AND PRESS TYPE USING LNG COLD ENERGY

摘要

PURPOSE: An ultralow temperature pressurized type hydrogen storage system using LNG cold energy is provided to ensure economic efficiency by obtaining cold energy for storing hydrogen from LNG. CONSTITUTION: An ultralow temperature pressurized type hydrogen storage system using LNG cold energy comprises an LNG storage tank(10), a hydrogen cooling heat exchanger(20), a hydrogen storage tank(30), and a seawater type heat exchanger(40). The hydrogen cooling heat exchanger receives LNG(Liquefied Natural Gas) from the LNG tank and cooling hydrogen provided from outside through heat exchange between the LNG and the hydrogen. The hydrogen storage tank stores the cooled hydrogen provided from the hydrogen cooling heat exchanger. The seawater type heat exchanger receives LNG passing through the hydrogen cooling heat exchanger and vaporizes LNG through heat exchange between the LNG and the sea water.
