In rocket engines, liquid hydrogen is frequently used as a coolant to cool the engine nozzle (regenerative cooling) and other parts before being mixed with the oxidizer (often liquid oxygen (LOX)) and burned. In such a rocket, even with thermally insulated containers it is impossible to avoid the heating of such a cold liquid, and the hydrogen will gradually evaporate. The resulting exhaust of such LH2 - LOX engines is very clean water with traces of ozone and hydrogen peroxide.
