• Resumen

  • The adsorption of hydrogen has extensively been studied on various nanoporous adsorbents with the driving force being the need to safely store this increasingly important energy vector. This chapter explores the research avenues that have been taken for the storage of hydrogen with zeolites, carbon-based materials, and metal-organic frameworks. Many studies have been devoted to characterization at 77 K and 1 bar.

    This chapter highlights that few materials meet the accepted requirements for vehicular hydrogen storage at 77 K and that no material seems to be of interest for hydrogen storage at room temperature. A general need to store the hydrogen under significant pressure is evident. It is clear that there is general necessity for nanoporous materials to stimulate stronger interactions with hydrogen for an adsorptive-based solution to be envisaged, and several strategies are described to this end.
