[0002] Liquid hydrogen (LH2), commonly known as liquid hydrogen, is a liquid obtained by cooling hydrogen. Liquid hydrogen needs to be stored at very low temperatures. The density of liquid hydrogen is about 70.8 kilograms per cubic meter, which is very low. It is usually used as a fuel for rocket launches and is now also used as a fuel for other means of transportation. Although liquid hydrogen has high storage requirements - it must be kept below -250°C to remain liquid, otherwise it will vaporize and evaporate, but the energy density of liquid hydrogen is 75% higher than that of high-pressure gaseous hydrogen, so vehicles using liquid hydrogen can achieve a relatively long driving range, which brings various practical benefits.
