SEOUL — South Korea’s standardization proposal for liquid hydrogen fuel tank technology was adopted as a draft standard at an international conference. Fuel tanks that store hydrogen in a liquid state are crucial components for urban air mobility vehicles.
Liquid hydrogen is created by cooling hydrogen gas to an extremely low temperature of about minus 253 degrees Celsius (minus 423 Fahrenheit). The liquified form has about ten times more energy density than the vapor state. South Korea has demonstrated technologies for the storage and transportation of liquid hydrogen in a regulation-free zone located in the eastern port city of Samcheok. Drones and tank trucks carrying special tanks capable of maintaining the high pressure of liquefied hydrogen were manufactured for demonstration.
