Hydrogen can be stored in containers or in materials. In materials it can exist in molecular or atomic forms. The atomic form can further exist as multiple phases. Molecular hydrogen can be adsorbed on the surface or can be present inside the material. In the current work, we demonstrate for the first time, a methodology to store hydrogen in nearly all conceivable forms. At the heart of this strategy is the novel concept of storage of molecular hydrogen in metal Pd nanocontainers. The existence of multiple phases of hydrogen is confirmed by x ray diffraction, Raman spectroscopy, nuclear magnetic resonance and pressure-composition isotherm measurements. Enhancement in storage capacity as compared to nanocrystals of the same mass is observed (36 percent increase at 1 atm and 25C). About 18 percent of the hydrogen stored is in the molecular form and interestingly this is achieved at room temperature and 1 atm pressure.
