Abstract
A system is described for the conversion of the energy in the wind over oceanic regions into hydrogen which can be used as a supplement to or replacement for fossil fuels. The system is based on the use of modified sailing vessels which serve as water electrolysis plants. In operation, the wind propels the vessel through the water in the manner common to all sailing vessels except that the vessel in this system does not carry a mast and does not need the ballasting characteristic of conventional sailcraft. The propulsion of the vessel causes an immersed screw propeller to power an electromagnetic generator, the electric current from which electrolytically decomposes water into hydrogen and oxygen. The hydrogen is stored on board the vessel by allowing it to combine with suitable metal alloys such as the Fe-Ti alloys to form a hydride. The metal alloy hydride is stored in cannisters which are allowed to desorb their hydrogen at sea for use as a fuel source, or alternatively may be discharged ashore through pipelines at suitable intervals.
