Cryo-adsorption is a method used for hydrogen storage where gaseous hydrogen at cryogenic temperatures (150—60 K) is physically adsorbed on porous material, mostly activated carbon. The achievable storage density is between liquid-hydrogen (LH₂) storage systems and compressed-hydrogen (CGH₂) storage systems.^[1]
