Abstract: In a fuel tank for containing a hydrogen storing material and a product generated by dehydrogenation reaction of the hydrogen storing material, comprising, a fuel chamber for containing the hydrogen storing material, a waste chamber for containing the product, and a tank envelope for containing the fuel chamber and the waste chamber, the fuel tank further comprises a partition wall fluidly separating the fuel chamber and the waste chamber from each other and being movable to change a ratio in volume between the fuel chamber and the waste chamber, and each of the fuel chamber and the waste chamber has a valve to be hermetically closed.

Abstract: A flexible bag for receiving flowable material is suspended, as from a gantry, and is tethered transversely and yet has substantially free movement along three sides for complete filling. The length of the tethers may be selected to prevent complete collapse of the bag when empty, and tubular perforated members having an “H” configuration within the bag may be provided for this purpose. Auxiliary structures provide for cooling of materials provided to the bag, their diffusion on inlet to the bag, their recirculation in the bag, and their removal from the bag. Accessories for use with wet gas provide for separation of inlet liquid and drainage of condensate within the bag.

Abstract: A low pressure gas storage system comprising an annular anchor ring, a granular bed within the ring, a flexible membrane of gas storage chamber positioned above the bed, and a flexible membrane of air chamber encompassing the gas storage chamber and exerting pressure thereon; and a plurality of flexible, radially-extending restraining means positioned against and over the air chamber to exert a predetermined pressure thereon.

Abstract: An expansible dry seal gasholder includes a piston disposed within a container side wall and a plurality of generally annular fender structures disposed between the piston and the side wall and spaced therefrom and from each other, with flexible fabric sealing members interconnecting the piston and the fender structures and the side wall and closing the spaces therebetween. Respectively pivotally mounted between the arms of a clevis at the top of each fender structure are generally L-shaped latch members, each having one end thereof connected by a roller chain to the upper end of the next innermost fender structure, with the latch member of the innermost fender structure being connected to the upper end of the piston. The clevis brackets are adjustable effectively to vary the lengths of the chains.
