Cryogenic energy storage (CES) is the use of low temperature (cryogenic) liquids such as liquid air or liquid nitrogen as energy storage.

Liquid oxygen is obtained from the oxygen found naturally in air by fractional distillation in a cryogenic air separation plant.

A 3He 4He dilution refrigerator is a cryogenic device that provides continuous cooling to temperatures as low as 2 mK, with no moving parts in the low temperature region.

Now, the reason we were able to come up with this is two key ideas One is that this is similar to a cryogenic Dewar, something you'd keep liquid nitrogen or liquid helium in.

Approximately 96 tonnes of superfluid helium 4 is needed to keep the magnets, made of copper clad niobium titanium, at their operating temperature of , making the LHC the largest cryogenic facility in the world at liquid helium temperature.

Of the 2008 world helium total production of about 32 million kg (193 million standard cubic meters) helium per year, the largest use (about 22 of the total in 2008) is in cryogenic applications, most of which involves cooling the superconducting magnets in medical MRI scanners.

Liquid oxygen has a density of 1.141 g cm3 (1.141 kg L or 1141 kg m3) and is cryogenic with a freezing point of 54.36 K ( 361.82 F, 222.65 C) and a boiling point of 90.19 K ( 297.33 F, 182.96 C) at 101.325 kPa (760 mmHg).
