Glass hollow fibers have an extraordinary high theoretical strength up to 12.9 GPa. Decreasing the size of the glass hollow fibers results in increasing strength. The hexagonal structures ensure the highest packing density and enlarge the storage capacity to maximum. The modular assembling allows for extraordinary shapes and geometries due to the freedom in spatial directions. The amount of hydrogen can be customized to all applications, from less than one liter up to thousands of liters.

The developed technology adopts outstanding characteristics of the material glass:

A high tensile strength, three times higher than steel, leads to extraordinary pressure resistances of hollow glass fibers used for hydrogen storage.

A decrease of the dimension results in an increase of the burst pressure. Therefore the tensile strength of glass is not a material constant but heavily dependent from the size and the shape!
