    Abstract: Dual-functional energy storage systems that couple ion extraction and recovery with energy storage and release are provided. The dual-functional energy storage systems use ion-extraction and ion-recovery as charging processes. As the energy used for the ion extraction and ion recovery processes is not consumed, but rather stored in the system through the charging process, and the majority of the energy stored during charging can be recovered during discharging, the dual-functional energy storage systems perform useful functions, such as solution desalination or lithium-ion recovery with a minimal energy input, while storing and releasing energy like a conventional energy storage system.

  • Patent number: 10995009
    Abstract: The production of NH3, Urea, UAN, and DAP, starting from inherently intermittent renewable energy, such as photovoltaic and wind power, is made economical by use of molten salt thermal energy storage (ESS) and water electrolyzer (WE) concentrated oxygen. The process inputs and equipment apply air; hydrogen-containing fuel, such as biomass; WE (concentrated O2 and H2 producing); thermal ESS equipped with a turbine and generator to steady the electricity input to the WE; and an ammonia plant. The thermal ESS enables minimally sized process equipment including, the WE, the air separation unit and less hydrogen storage. The concentrated oxygen from the water electrolyzer uniquely enables high-temperature thermal ESS input, water and CO2 collection and other fertilizer products, including Urea, UAN and DAP. DAP production is facilitated by using WE high-purity O2 oxidation and ammonium nitrate is similarly facilitated by anhydrous NH3 oxidation.

    Abstract: An Electrical Power Plant (EPP) derives power through a semi-cone roof and platform serving as a source of distributed electrical/storage energy. Electric power is generated through renewable resource systems mounted upon and within the semi-cone roof. Two paths generate electrical power/heat. A Direct path uses solar panels and wind turbines. An Indirect path has a Compact Solar Heat Generator (CSHG) that generates electrical power and/or heat through a High Temperature Electrolysis (HTE) system to produce hydrogen and oxygen which are fed into Fuel Cells to produce electrical power, pure water and waste heat. The waste heat and pure water are then fed into the Computer Distributer Controller Tank (CDCT) as part of cogenerated energy. These paths are the power input to the EPP that provides a distributed source of electrical/storage power. The CDCT also provides a path for hot water to the Hot Water Heater or Boiler.

When secondary fuels are combusted by the primary fuel, the by-products include heat, water and other more stable by-product materials. When the secondary fuel is a hazardous waste or a radioactive material and either is bound to thermite before combustion, the by-products are no longer hazardous or have significantly reduced radiation levels after one or more passes. Embodiments of the present invention relate to the method for accelerating the decay of hazardous and/or radioactive waste products, and more particularly they relate to the nuclear transmutation of heavy radioactive elements into lighter ones with shorter half-lives and then finally to stable daughter products. Therefore, the invented process relates to reducing the long-term toxicity of hazardous and/or radioactive waste and to, an economic and effective process facility for doing so.

  • Patent number: 9315796
    Abstract: Disclosed is a method for activating a catalyst using the photothermal effects of photothermal nanomaterials, and more particularly to a method of activating a catalyst at a temperature, at which the catalyst has low or no activity, by irradiating a catalyst-photothermal nanomaterial composite with light. The method can activate the catalyst by increasing only the temperature around the nanomaterials without substantially changing the temperature of the reaction medium. A catalyst that generally has high activity at room temperature can be activated even at low temperature. Catalysts having high activity only under mild conditions are immobilized on photothermal nanomaterials so that they have activity even under low temperature and extreme conditions. The invention is useful when a catalyst substrate unstable at room temperature is used or a catalytic product unstable at room temperature is produced.

  • Publication number: 20150144501
    Abstract: A method for conditioning hydrogen includes positioning hydrogen on a suction side of an electrochemical compressor. The hydrogen includes at most a fractional amount of an extraneous species. The electrochemical compressor includes a first electrode on a suction side and a second electrode on a pressure side and is configured to apply an electrical potential between the first and second electrodes. The method further includes transporting ions of the hydrogen through a membrane of the electrochemical compressor via the electrical potential in order to increase a hydrogen partial pressure on the pressure side of the electrochemical compressor and such that the extraneous species remains on the suction side of the electrochemical compressor.

  • Patent number: 9027342
    Abstract: A supplementary intercooler cools engine air after it has passed through the turbocharger of a vehicle's turbocharged internal combustion engine, but before it enters the engine. The unit has an inlet for capturing the turbo's air charge and an outlet for routing the air charge to the engine after passing through the intercooler. A container stores water until it is needed and a water pump transfers water from the container to the unit. This loosened bond of water is then sprayed on capacitor plates under turbo pressure to be converted into hydrogen and injected into the air intake stream making it a totally “hydrogen-on-demand” intercooler.

  • Patent number: 8986518
    Abstract: The present aspects of an embodiment make more efficient use of hydrogen on-demand (hereinafter “HoD”) systems, thereby improving fossil-fuel-powered systems on the market. One main aspect uses a disposable cartridge in which the electrolytic process takes place to separate gas molecules from a solution that uses a substantially dry-cell design. Generally, the aspects include a replaceable and reusable cartridge for the flow of electrolyte solution using a pump, which may include a variety of safety features. A HoD cartridge generator has a plurality of staggered conductive material members that require electrolyte solution to flow between them, from one or more inlets to one or more outlets, using one or more specified paths. A conventional or specially-formulated electrolyte solution may be used. One or more sensors allow the generator to have a steady flow of solution in and a steady flow of liquid-gas mixture out of the system.
