1. A hydrogen storage device, at least comprising a container having a first volume, with a bulk material disposed in the container, wherein the bulk material comprises at least a multitude of compacts produced by compression, wherein each compact comprises at least a first material capable of storing hydrogen and a second material as binder for the first material that was in pulverulent form before the production by compression, wherein interstices are formed between the compacts, which, in the course of intercalation and release of hydrogen, are variable in size to compensate for the change in size of the compacts.
 
9. A method comprising using a multitude of compacts as a bulk material for a hydrogen storage device, wherein each of the compacts comprises at least a first material capable of storing hydrogen and a second material as binder for the first material, wherein interstices between the compacts vary in size during intercalation and release of hydrogen to compensate for change in size of the compacts.
