| 释义 |
A liquid hydrogen tank car, also called liquid hydrogen tank wagon or liquid hydrogen tanker wagon is a railroad tank car designed to carry cryogenic liquid hydrogen (LH2). LH2 tank cars with a capacity of {{convert|17000|lb|kg|0}} are used for transcontinental transport.[1][2] DesignThe pressure within the tank is {{convert|25|psi|kPa|abbr=on|lk=on}} or lower[3][4] with a temperature below 20.27 K ({{convert|−423.17|°F|°C|disp=or}}) and a boil-off rate of 0.3% to 0.6% per day[5] The tank is double walled like a vacuum flask with multi-layer insulation, with the valves and fittings enclosed in a cabinet at the lower side or end of the car.
