Since the VONEN H2 MH metal hydride storage units do not suffer from self-discharge, hydrogen can be stored for years without any loss of energy through self-discharge.
For the storage of 1 kg hydrogen gas in VONEN MH Storages, you need an MH storage of the size shown in the picture below (dimensions in mm):

The weight of the VONEN MH Storage assembly for 1 kg hydrogen is 115 kg.
H2 is stored at low (2-4 bar) pressure, and the Metal Hydride guarantees a safe storage. See an example of fire safety of a VONEN MH Storage charged with hydrogen below:
