Liquid Hydrogen
Liquid hydrogen, also known as slush hydrogen, is non-corrosive and colorless at 20 K. Liquid hydrogen, which requires cryogenic storage, is often used as concentrated form of hydrogen storage. Liquid hydrogen tanks can store 0.070 kg L −1 of liquid hydrogen compared to 0.030 kg L −1 as seen in case of compressed gas tanks.
