Cryogenic Propellants

Cryogenic propellants are rocket propellants that are stored at very low temperatures. Cooling some common room-temperature gases allow them to be used as high-performance rocket propellants. Typically, cryogenic propellants are stored in a liquid state at their boiling point. Examples of Cryogenic propellants are LOX (liquid oxygen) and LH2 (liquid hydrogen).
