Due to its high energy density hydrogen is a capable energy carrier to store the electrical energy surplus resulting from energy production by wind and solar energy in chemical energy. In this context, corrosion stable, pressure resistant glasses offer a promising opportunity for long term hydrogen storage e.g. at high pressure in glass capillaries.
In this context, investigations of hydrogen permeation and diffusion can provide important fundamental knowledge to evaluate the applicability. Different sample geometries as planary, bulb shaped, capillary shaped, as well as powders are compared in order to evaluate the experimental operability and the sensitivity of each approach. Limiting factors are e.g. gas thight sealing of planar samples, wall thickness of small glass bulbs, availability of glass capillaries and a defined grain of powders. High pressure experiments and the application of fast furnaces to ensure quick heating to the extraction temperature using vacuum hot extraction coupled with MS. The correctness is ensured comparing the obtained results of the mentions geometries emong each other as well as with literature data.
