  • Patent number: 8845998
    Abstract: A catalyst has a long life span and efficiently separates hydrogen from water. A first metal element (Ni, Pd, Pt) for cutting the combination of hydrogen and oxygen and a second metal element (Cr, Mo, W, Fe) for helping the function of the first metal element are melted in alkaline metal hydroxide or alkaline earth metal hydroxide to make a mixture heated at a temperature above the melting point of the hydroxide to eject fine particles from the liquid surface, bringing steam into contact with the fine particles. Instead of this, a mixture of alkaline metal hydroxide and metal oxide is heated at a temperature above the melting point of the alkaline metal hydroxide to make metal compound in which at least two kinds of metal elements are melted, and fine particles are ejected from the surface of the metal compound to be brought into contact with steam.

  • Publication number: 20140261132
    Abstract: Systems and methods for storing energy in gaseous form in submerged thin-walled tanks are secured to the ocean or lake floor but are open to the water at the tank bottoms and are configured to be filled with gas while submerged. A conduit operatively connected to the tanks provides flow from a surface source of an energy-containing gas to the tank interiors. Surface or subsurface pumping apparatus which may include piston-less pressure cylinders or have leveraged pistons provide a preselected flow rate of the energy-containing gas into the containment structure interior against a back pressure essentially equal to the static pressure of the body of water at the location of the tank to displace an equivalent volume of water through the open bottom. The conduit can be configured to allow heat transfer to vaporize liquefied gas prior to storage. Hydrogen gas can be generated and stored within the tank using Aluminum activated with Galinstan.

  • Patent number: 8828108
    Abstract: An apparatus, system, and method are disclosed for capturing electrical energy from a process designed for producing hydrogen. An electrode is placed within a stream of liquid alkali metal that flows through a titration module and interacts with water to produce, among other byproducts, hydrogen. Another electrode is placed within a reaction chamber that houses the water. The electrodes can then be coupled to a terminal, and during the hydrogen generation process (when the liquid alkali metal and water interact) the stream of liquid alkali metal acts as an anode and the electrode in the water as a cathode. Current flows, and energy is captured and made available as electrical energy at the terminal, which can be connected to electrical loads. The terminal may be connected with the terminal of a fuel cell that is consuming the hydrogen that is being produced, thus providing additional voltage and/or current.

  • Patent number: 8821834
    Abstract: The present invention concerns a hydrogen gas-generating apparatus (10) comprising (1) a reservoir (100) comprising an aqueous component (110), (2) a fuel compartment (200) comprising a solid metal borohydride fuel component (210), and (3) a reaction chamber (300) comprising an aerogel catalyst (310). A first fluid path introduces the aqueous component into the fuel compartment where the solid metal borohydride fuel component is dissolved into a liquid metal borohydride fuel component (210?). A second fluid path introduces the liquid metal borohydride fuel component into the reaction chamber to produce a hydrogen gas by means of a hydride-water oxidation reaction that is accelerated by the aerogel catalyst. The temperature and/or pressure of the reaction chamber are predetermined to maintain the water in the borate byproduct to be substantially in the liquid phase to minimize the precipitation of the borate byproduct.

  • Publication number: 20140241979
    Abstract: The present invention relates to method for recycling alkaline waste water from a stainless steel slag treatment process wherein stainless steel slag is brought into contact with water thereby producing said waste water, which waste water contains heavy metals, including at least chromium, and has a pH of at least 12. The waste water is recycled by using it for treating an alkaline granular carbonatable material, which contains aluminium metal, in order to oxidise the aluminium metal contained therein. This material is in particular municipal waste incinerator bottom ash which can, after the treatment of the present invention, safely be used as fine or coarse aggregate in bonded applications such as concrete, mortar and asphalt. During the treatment with the alkaline waste water, hydrogen gas is produced which is captured and used to produce energy by means of a cogeneration device.
