Electrolytically produced hydrogen using solar energy

Solar cells are mounted on a ship, with sea water used as the electrolyte. The produced hydrogen is compressed for storage on board. A ship has solar cells that supply power not only to electrolyze the sea water and produce hydrogen but also to provide power to run compressors and to navigate the ship. Power for this is supplied directly as electrical energy or indirectly by burning some of the hydrogen. The solar cells occupy the major portion of the deck surface and are divided into a number of sets. Each set contains three stacked plates. The bottom plate is firmly attached to the ship and the other two may be fanned out about horizontal axes to provide a maximum area open to the sun. The plates can be retracted in inclement weather. Further solar collectors can be floated off-board. Sea water is filtered and desalinated before being passed to the electrolysis cells. The hydrogen produced there is compressed and stored in spherical pressure vessels that are placed both above and below ...
