In an electrostatic separating apparatus which separates supplied substances containing sheet-like substances into conductive substances and insulating substances by using electrostatic force and corona discharge together, a ground electrode unit has a carrier belt tensioned for a plurality of rotation rollers. An opposite electrode unit is provided with a first electrostatic electrode, a corona electrode, and a second electrostatic electrode in this order from a supply side of the supplied substances. A removing unit separates and removes the insulating substances attached to the ground electrode unit.
A gas storage assembly that has an enclosure within which are disposed at least about 100 inorganic tubules are present for each cubic micron of volume of the enclosure. The assembly has a storage capacity of at least 20 grams of hydrogen per liter of volume of the enclosure.
