STORING METHOD AND APPARATUS FOR HYDROGEN GAS

摘要

PROBLEM TO BE SOLVED: To provide a storing method and an apparatus for hydrogen gas capable of storing high density hydrogen in a safe and easy to handle state while keeping evaporation loss small. SOLUTION: Hydrogen gas is stored in the hydrogen container at an air pressure larger than atmospheric pressure by introducing hydrogen gas into the hydrogen gas container 3 made of fiber reinforced plastics, dipping the container for hydrogen gas in cryogenic refrigerant 11 consists of liquid nitrogen or inert gas and cooling inside the hydrogen gas container 3 at a temperature equal to or less than inversion temperature of hydrogen.
