  • Hydrogen tank — A Hydrogen tank (other names cartridge or canister) is used for hydrogen storage, most tanks are made of composite material because of hydrogen embrittlement. Some tanks are used for fixed storage others are exchangeable for refueling at a… …   Wikipedia

  • 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… …   Wikipedia

  • Pressure swing adsorption — (PSA) is a technology used to separate some gas species from a mixture of gases under pressure according to the species molecular characteristics and affinity for an adsorbent material. It operates at near ambient temperatures and so differs from …   Wikipedia

  • Liquid hydrogen — (LH2 or LH2) is the liquid state of the element hydrogen. It is a common liquid rocket fuel for rocket applications. Hydrogen is found naturally in the molecular H2 form.To exist as a liquid, H2 must be pressurized and cooled to a very low… …   Wikipedia
