20130142701 | ENGINEERED FUEL STORAGE, RESPECIATION AND TRANSPORT - Techniques, systems and material are disclosed for thermochemical regeneration of biomass into renewable engineered fuel, storage of the renewable engineered fuel, respeciation of the renewable engineered fuel and transport. In one aspect, a method includes generating low density hydrogen fuel from biomass dissociation at a first location of a low elevation. The low density hydrogen fuel is self-transported in a pipeline to a second location at a higher elevation than the first location by traveling from the first location to the second location without adding energy of pressure. A high density hydrogen carrier is generated at the second location of higher elevation by reacting the low density hydrogen fuel with at least one of a carbon donor, a nitrogen donor and an oxygen donor harvested from industrial waste. The high density hydrogen carrier is delivered to a third location of a lower elevation than the second location while providing pressure or kinetic energy. | 06-06-2013 |
20130145761 | SYSTEMS AND METHODS FOR PROVIDING SUPPLEMENTAL AQUEOUSTHERMAL ENERGY - Systems and methods for collecting, storing, and conveying aqueous thermal energy are disclosed. In a particular embodiment, a floating film retains solar energy in a volume of water located under the film. A series of curtains hanging from a bottom surface of the film define a passage between a periphery of the film and a center of the film to direct the heated water at the center of the film. The heated water is circulated to deliver the heat to a dissociation reactor and/or donor substance. The donor is conveyed to the reactor and dissociated. | 06-13-2013 |
20130149621 | FUEL-CELL SYSTEMS OPERABLE IN MULTIPLE MODES FOR VARIABLE PROCESSING OF FEEDSTOCK MATERIALS AND ASSOCIATED DEVICES, SYSTEMS, AND METHODS - Fuel cells for selectively reacting a feedstock material with or without generating electricity, and associated systems and methods are disclosed. A fuel cell system in accordance with a particular embodiment includes a first electrode positioned in a first region, a second electrode positioned in a second region, an ion-transport medium between the first and second regions, and an electrical circuit connected between the first and second electrodes. The system is operable in a first mode to react the feedstock material by a non-electricity-generating reaction to produce a product and in a second mode to react the feedstock material by an electricity-generating reaction to produce electricity. A controller receives an input (e.g., corresponding to a change in demand for electricity) and causes the system to switch between operating in the first mode and operating in the second mode in response to the input. | 06-13-2013 |
20130153399 | GEOTHERMAL ENERGIZATION OF A NON-COMBUSTION CHEMICAL REACTORAND ASSOCIATED SYSTEMS AND METHODS - Systems and methods for heating a non-combustion chemical reactor with thermal energy from a geothermal heat source are described. A working fluid is directed from the geothermal heat source to the chemical reactor to transfer heat. The working fluid can be circulated in a closed system so that it does not contact material at the geothermal heat source, or in an open system that allows the working fluid to intermix with material at the geothermal heat source. When intermixing with material at the geothermal heat source, the working fluid can transport donor substances at the geothermal heat source to the chemical reactor. | 06-20-2013 |
20130156504 | SYSTEMS AND METHODS FOR COLLECTING AND PROCESSING PERMAFROSTGASES, AND FOR COOLING PERMAFROST - Systems and methods for collecting and processing permafrost gases and for cooling permafrost are disclosed herein. A method in accordance with a particular embodiment for processing gas in a permafrost region includes obtaining a gas from a sacrificial area of a thawing permafrost region, dissociating the gas in a non-combustive chemical process, and circulating a constituent of the gas through a savable area of the thawing permafrost region to cool the savable area. In particular embodiments, this process can be used to cool selected areas of permafrost and/or create clean-burning fuels and/or other products from permafrost gases. | 06-20-2013 |
20130158828 | REDUCING AND/OR HARVESTING DRAG ENERGY FROM TRANSPORT VEHICLES, INCLUDING FOR CHEMICAL REACTORS, AND ASSOCIATED SYSTEMS AND METHODS - The present disclosure is directed to systems and methods for reducing and/or harvesting drag energy from transport vehicles. A system in accordance with a particular embodiment includes a mobile transport platform, a donor substance source carried by the platform, and a thermochemical reactor carried by the platform and coupled to the donor substance. The reactor is configured to carry out a non-combustion dissociation process that dissociates the donor substance into a first constituent and a second constituent. An energy extraction system carried by the transport platform and positioned to extract energy from an airstream passing the transport platform is coupled to the reactor to provide energy for the dissociation process. | 06-20-2013 |
20130174486 | CHEMICAL PROCESSES AND REACTORS FOR EFFICIENTLY PRODUCING HYDROGEN FUELS AND STRUCTURAL MATERIALS, AND ASSOCIATED SYSTEMS AND METHODS - Chemical processes and reactors for efficiently producing hydrogen fuels and structural materials and associated systems and methods. A representative process includes dissociating a hydrogen donor into dissociation products by adding energy to the hydrogen donor, wherein the energy includes waste heat generated by a process other than dissociating the hydrogen donor. The process can further include providing, from the dissociation products, a structural building block and/or a hydrogen-based fuel, with the structural building block based on carbon, nitrogen, boron, silicon, sulfur, and/or a transition metal. | 07-11-2013 |
