Effects of Promoters in Hydrogen Hydrates Formation

Hydrogen storage in large quantities is a main factor to produce ‘‘Hydrogen Economy’’. Recently, with the development of the hydrogen economy and fuel cell vehicles, the manner of storing and delivering large quantities of hydrogen arises as a major problem. Nowadays several hydrogen storage methods are available. Technologies are being developed and/or engineered other than the classical compression and liquefaction of hydrogen, which are based on the chemical (e.g., ammonia) and physical (e.g., carbon nanotubes) adsorption of H2. Also, a novel technology is in progress, which is based on clathrate hydrates of hydrogen. In this article has been tried to discuss at length the possibility of hydrogen storage in hydrate and thermodynamic models.
