One element of the hydrogen economy that is essential is , Hydrogen Storage. Hydrogen must be kept in a solid state, under high pressure, or at low temperatures due to its low density and great flammability.
Application required energy density, safety requirements, and cost all influence the selection of hydrogen storage options. A key element of the hydrogen economy is hydrogen storage. Hydrogen must always be stored at high pressure and low temperature. It is also a solid material due to its low density and high flammability.
