What type of substances do cryogenic liquid storage tanks typically store?

Cryogenic liquid storage tanks are designed to store substances at extremely low temperatures, typically below -150 degrees Celsius (-238 degrees Fahrenheit). The primary examples of substances that are stored in these types of tanks include oxygen, liquid nitrogen, and other gases that can be liquefied such as argon and helium.

Oxygen in its liquid form is utilized in various industries including medical and aerospace, while liquid nitrogen is commonly used for refrigeration, cryopreservation, and in various industrial processes. These substances not only require cryogenic conditions for storage but also have broad applications across multiple sectors such as healthcare, food preservation, and manufacturing.

In contrast, the other options involve materials that either do not require such extreme conditions or pertain to entirely different categories of storage. Liquid mercury and acids would be stored in specialized containers designed for hazardous chemical handling, solid fuels and oils are typically stored in standard tanks under ambient temperature conditions, and radioactive materials require very specific containment strategies that differ from those used for cryogenic liquids.
