Experimental investigation of hydrogen storage in capillary arrays

We present the results of the experimental investigation of hydrogen storage in glass capillary arrays. It is demonstrated that quartz-epoxy capillary arrays can have extremely high gravimetric and volumetric capacity, exceeding US DOE 2010 target values. The new method of pressurized hydrogen loading and releasing is developed based on plugging up the capillaries with stoppers in high-pressure environment.
