text: # Cryo-adsorption
  
  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 $(LH_2)$ storage systems and compressed-hydrogen $(CGH_2)$ storage systems.
