Hydrogen is the lightest and most abundant element in the universe. It is a colorless, odorless, flammable gas with extremely high combustibility and very low solubility in water. The density of hydrogen is 0.089 g/L (101.325 kPa, 0°C), which is only one-fourteenth that of air, making it the lightest known gas. As a versatile zero-carbon energy carrier, it can drive decarbonization efforts in sectors such as transportation, manufacturing, and energy. Hydrogen gas has a wide range of applications in various fields such as industry, energy, food manufacturing, medicine, and aerospace.
