The cryogenic storage tank has been scaled up, occupying less land and reducing storage costs. Its simple structure and easy construction further lower construction costs.
With the development of science and technology, the technology of storing materials in cryogenic tanks under normal pressure is becoming increasingly mature. The construction of domestic cryogenic tanks under normal pressure is increasing, moving towards large-scale development. Compared with other storage methods, cryogenic tanks under normal pressure have many advantages: compared to vacuum tanks and spherical tanks, cryogenic tanks have lower storage pressure, thus providing better safety. As cryogenic tanks achieve large-scale development, they occupy less land, reduce storage costs, have simple tank structures, are easy to construct, and lower construction costs. Common storage media include liquefied natural gas (LNG) (-162°C), liquid oxygen (-183°C), liquid nitrogen (-196°C), liquid argon (-186°C), liquid ethane (-89°C), ethylene (-104°C), etc.
