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.
