  2. Liquefaction of gases - Wikipedia

    en.wikipedia.org/wiki/Liquefaction_of_gases

    Many gases can be put into a liquid state at normal atmospheric pressure by simple cooling; a few, such as carbon dioxide, require pressurization as well. Liquefaction is used for analyzing the fundamental properties of gas molecules (intermolecular forces), or for the storage of gases, for example: LPG, and in refrigeration and air conditioning.

  3. Seasonal thermal energy storage - Wikipedia

    en.wikipedia.org/.../Seasonal_thermal_energy_storage

    Storage temperatures of 90 °C (194 °F) are sufficient to supply both domestic hot water and space heating. The first such house was MIT Solar House #1, in 1939. An eight-unit apartment building in Oberburg , Switzerland was built in 1989, with three tanks storing a total of 118 m 3 (4,167 cubic feet) that store more heat than the building ...

  4. Oxygen storage - Wikipedia

    en.wikipedia.org/wiki/Oxygen_storage

    Methods of oxygen storage for subsequent use span many approaches, including high pressures in oxygen tanks, cryogenics, oxygen-rich compounds and reaction mixtures, and chemical compounds that reversibly release oxygen upon heating or pressure change. O 2 is the second most important industrial gas.

  5. Gas cylinder - Wikipedia

    en.wikipedia.org/wiki/Gas_cylinder

    A gas cylinder is a pressure vessel for storage and containment of gases at above atmospheric pressure. Gas storage cylinders may also be called bottles . Inside the cylinder the stored contents may be in a state of compressed gas, vapor over liquid, supercritical fluid , or dissolved in a substrate material, depending on the physical ...

  6. Compressed carbon dioxide energy storage - Wikipedia

    en.wikipedia.org/wiki/Compressed_carbon_dioxide...

    Compressed carbon dioxide energy storage can be used to store electrical energy at grid scale. The gas is well suited to this role because, unlike most gases, it liquifies under pressure at ambient temperatures, so occupies a small volume. Energy Storage News reported that it may be "a cheaper form of energy storage than lithium-ion batteries". [1]

  7. Liquefied natural gas - Wikipedia

    en.wikipedia.org/wiki/Liquefied_natural_gas

    Because of large volumes it is not practical to store natural gas, as a gas, near atmospheric pressure. However, when liquefied, it can be stored in a volume 1/600th as large. This is a practical way to store it but the gas must be kept at −260 °F (−162 °C). There are two processes for liquefying natural gas in large quantities.

  9. Horton sphere - Wikipedia

    en.wikipedia.org/wiki/Horton_Sphere

    A Horton sphere (sometimes spelled Hortonsphere), also referred to as a spherical tank or simply sphere, is a spherical pressure vessel, which is used for industrial-scale storage of liquefied gases. Example of materials that can be stored in Horton spheres are liquefied petroleum gas (LPG), liquefied natural gas (LNG), and anhydrous ammonia. [1]
