Hydrogen storage mechanism

On the other hand, also carbon nanofibers based on stacked graphite layers seem show appreciable gravimetric storage capacity at room temperature and at moderate pressure (about 120 bar) [133], but other experimental results obtained on similar nano-materials appear contradictory [134], and the hydrogen storage mechanism is still far to be understood.

The reaction of (1.16) follows reverse path to the thermal decomposition reaction of (1.13) and proceeds at room temperature and only slight overpressure of hydrogen supply. This presents a new mechanical activation route to manufacturing of nanomaterials for hydrogen storage.
