How is liquid oxygen stored?

Liquid oxygen is generally stored in tanks, cylinders, containers, and dewars. Tanks are large, stationary oxygen storage containers holding up to 80,000 gallons of O₂. Cylinders are smaller, portable containers that can hold up to 6,000 liters of O₂ in its compressed form. Containers are usually large airtight tanks that are used to store liquid oxygen or other cryogenic liquids. Dewars are vacuum-insulated vessels designed to store and transport liquid oxygen, nitrogen, and other cryogenic liquids.
