Complex Hydride Compounds with Enhanced Hydrogen Storage Capacity  

SciTech Connect (OSTI)

The United Technologies Research Center (UTRC), in collaboration with major partners Albemarle Corporation (Albemarle) and the Savannah River National Laboratory (SRNL), conducted research to discover new hydride materials for the storage of hydrogen having on-board reversibility and a target gravimetric capacity of ? 7.5 weight percent (wt %). When integrated into a system with a reasonable efficiency of 60% (mass of hydride / total mass), this target material would produce a system gravimetric capacity of ? 4.5 wt %, consistent with the DOE 2007 target. The approach established for the project combined first principles modeling (FPM - UTRC) with multiple synthesis methods: Solid State Processing (SSP - UTRC), Solution Based Processing (SBP - Albemarle) and Molten State Processing (MSP - SRNL). In the search for novel compounds, each of these methods has advantages and disadvantages; by combining them, the potential for success was increased. During the project, UTRC refined its FPM framework which includes ground state (0 Kelvin) structural determinations, elevated temperature thermodynamic predictions and thermodynamic / phase diagram calculations. This modeling was used both to precede synthesis in a virtual search for new compounds and after initial synthesis to examine reaction details and options for modifications including co-reactant additions. The SSP synthesis method involved high energy ball milling which was simple, efficient for small batches and has proven effective for other storage material compositions. The SBP method produced very homogeneous chemical reactions, some of which cannot be performed via solid state routes, and would be the preferred approach for large scale production. The MSP technique is similar to the SSP method, but involves higher temperature and hydrogen pressure conditions to achieve greater species mobility. During the initial phases of the project, the focus was on higher order alanate complexes in the phase space between alkaline metal hydrides (AmH), Alkaline earth metal hydrides (AeH2), alane (AlH3), transition metal (Tm) hydrides (TmHz, where z=1-3) and molecular hydrogen (H2). The effort started first with variations of known alanates and subsequently extended the search to unknown compounds. In this stage, the FPM techniques were developed and validated on known alanate materials such as NaAlH4 and Na2LiAlH6. The coupled predictive methodologies were used to survey over 200 proposed phases in six quaternary spaces, formed from various combinations of Na, Li Mg and/or Ti with Al and H. A wide range of alanate compounds was examined using SSP having additions of Ti, Cr, Co, Ni and Fe. A number of compositions and reaction paths were identified having H weight fractions up to 5.6 wt %, but none meeting the 7.5 wt%H reversible goal. Similarly, MSP of alanates produced a number of interesting compounds and general conclusions regarding reaction behavior of mixtures during processing, but no alanate based candidates meeting the 7.5 wt% goal. A novel alanate, LiMg(AlH4)3, was synthesized using SBP that demonstrated a 7.0 wt% capacity with a desorption temperature of 150C. The deuteride form was synthesized and characterized by the Institute for Energy (IFE) in Norway to determine its crystalline structure for related FPM studies. However, the reaction exhibited exothermicity and therefore was not reversible under acceptable hydrogen gas pressures for on-board recharging. After the extensive studies of alanates, the material class of emphasis was shifted to borohydrides. Through SBP, several ligand-stabilized Mg(BH4)2 complexes were synthesized. The Mg(BH4)2*2NH3 complex was found to change behavior with slightly different synthesis conditions and/or aging. One of the two mechanisms was an amine-borane (NH3BH3) like dissociation reaction which released up to 16 wt %H and more conservatively 9 wt%H when not including H2 released from the NH3. From FPM, the stability of the Mg(BH4)2*2NH3 compound was found to increase with the inclusion of NH3 groups in the inner-Mg coordination

Kinetics Study of Solid Ammonia Borane Hydrogen Release Modeling and Experimental Validation for Chemical Hydrogen Storage  

SciTech Connect (OSTI)

Ammonia borane (AB), NH3BH3, is a promising material for chemical hydrogen storage with 19.6 wt% gravimetric hydrogen capacity of which 16.2 wt% hydrogen can be utilized below 200C. We have investigated the kinetics of hydrogen release from AB and from an AB-methyl cellulose (AB/MC) composite at temperatures of 160-300C using both experiments and modeling. The purpose of our study was to show safe hydrogen release without thermal runaway effects and to validate system model kinetics. AB/MC released hydrogen at ~20C lower than neat AB and at a rate that is two times faster. Based on the experimental results, the kinetics equations were revised to better represent the growth and nucleation process during decomposition of AB. We explored two different reactor concepts; Auger and fixed bed. The current Auger reactor concept turned out to not be appropriate, however, we demonstrated safe self-propagation of the hydrogen release reaction of solid AB/MC in a fixed bed reactor.

Hydrogen transfer in transformations of olefin and thiophene compounds for the refining of gasoline fractions  

Science Journals Connector (OSTI)

Abstract Hydrogen transfer reactions in the transformations of mixtures of model hydrocarbons (hydrogen donors and acceptors) on zeolite catalysts were studied. Hydrogen donors were represented by various classes of hydrocarbons, and acceptorsby unsaturated (olefin) and thiophene compounds. The [H]-donor activity series of hydrocarbons was revealed. Strong differences in the transformation pathways of 1-hexene and 1-octene under the conditions of catalytic refining were demonstrated. A new method for the refining of low-rank gasoline fractions was proposed. The method is based on the hydrogen transfer reactions between hydrogen donor hydrocarbons and hydrogen acceptor hydrocarbons, which proceed without molecular hydrogen. The proposed method allows the simultaneous removal of sulfur (more than 95%) and unsaturated (more than 90%) compounds.

A rechargeable device that stores and discharges hydrogen is described. The device stores hydrogen in a solid form and supplies hydrogen as a gas when needed. The solid storage medium may be metal hydride in a ground particle form that avoids the need for compaction or other treatment. Dividers partition a container into separate chambers, each provided with a matrix, formed from an appropriate material like a thermally-conductive aluminum foam, which forms a number of cells. For proper chamber size, the ratio of chamber length to container diameter should be between about 0.5 and 2. Metal hydride particles (or other hydrogen storage medium) may be placed within the cells, which help prevent excessive particle settling. The container is provided with a hydrogen transfer port through which hydrogen gas passes upon either discharging from or charging of the metal hydride particles. A filter may be placed within the port to allow hydrogen to flow but prevent particles from escaping. A heat transferring surface is formed by, for instance, a channel that is thermally coupled with the aluminum foam. Fluid flows through the channel to deliver or remove heat during the respective hydrogen discharging or charging processes.

Tunable hydrogen storage in magnesiumtransition metal compounds: First-principles calculations  

Science Journals Connector (OSTI)

Magnesium dihydride (MgH2) stores 7.7?wt?% hydrogen but it suffers from a high thermodynamic stability and slow (de)hydrogenation kinetics. Alloying Mg with lightweight transition metals (TM) (=Sc,Ti,V,Cr) aims at improving the thermodynamic and kinetic properties. We study the structure and stability of MgxTM1?xH2 compounds, x=[01], by first-principles calculations at the level of density functional theory. We find that the experimentally observed sharp decrease in hydrogenation rates for x?0.8 correlates with a phase transition of MgxTM1?xH2 from a fluorite to a rutile phase. The stability of these compounds decreases along the series Sc, Ti, V, and Cr. Varying the TM and the composition x, the formation enthalpy of MgxTM1?xH2 can be tuned over the substantial range of 02 eV/f.u. Assuming however that the alloy MgxTM1?x does not decompose upon dehydrogenation, the enthalpy associated with reversible hydrogenation of compounds with a high magnesium content (x=0.75) is close to that of pure Mg.

Thermal Stability and Hydrogen Release Kinetics of Ammonia Borane Under Vehicle Storage Conditions  

SciTech Connect (OSTI)

Ammonia borane (AB) is a promising chemical hydrogen storage material for H2 powered fuel-cell vehicles (FCVs) owing to its considerable hydrogen density and stability under typical ambient conditions. U.S. Department of Energy (DOE) Technical Targets for on-board hydrogen storage systems in 2015 provide a requirement for operating temperatures in full-sun exposure as high as 60C (50C by 2010) [1]. The purpose of this work is to investigate the thermal stability of solid AB during storage on-board a FCV at 40 to 60C. Calorimeter measurements and calculation models are used to estimate AB thermal stability and H2 release kinetics under isothermal, adiabatic, and cooled storage conditions as a function of storage time, temperature, and AB purity.

Investigations of release phenomenon of volatile organic compounds and particulates from residual storage chip piles  

SciTech Connect (OSTI)

This paper outlines the method for estimating Particulate Matter and Volatile Organic Compounds (VOCs) emissions from wood handling and storage operations at a pulp mill. Fugitive particulate matter emissions from wood handling and storage operations are due to material load/dropout operations, wind erosion from storage piles and vehicular traffic on paved roads. The particulate matter emissions are a function of a number of variables like windspeed, surface moisture content, material silt content, and number of days of precipitation. Literature review attributes VOC emissions to biological, microbiological, chemical, and physical processes occurring in wood material storage pile. The VOC emissions are from the surface of these piles and the VOC released during retrieval of chips from the pile. VOC emissions are based on the chip throughput, number of turnovers, moisture content and surface area of the pile. The emission factors with the requisite calculation methodology to be utilized for quantifying VOC emissions from chip piles has been discussed in this paper.

Over the course of fifty-three years, LLNL had six acute releases of tritiated hydrogen gas (HT) and one acute release of tritiated water vapor (HTO) that were too large relative to the annual releases to be included as part of the annual releases from normal operations detailed in Parts 3 and 4 of the Tritium Dose Reconstruction (TDR). Sandia National Laboratories/California (SNL/CA) had one such release of HT and one of HTO. Doses to the maximally exposed individual (MEI) for these accidents have been modeled using an equation derived from the time-dependent tritium model, UFOTRI, and parameter values based on expert judgment. All of these acute releases are described in this report. Doses that could not have been exceeded from the large HT releases of 1965 and 1970 were calculated to be 43 {micro}Sv (4.3 mrem) and 120 {micro}Sv (12 mrem) to an adult, respectively. Two published sets of dose predictions for the accidental HT release in 1970 are compared with the dose predictions of this TDR. The highest predicted dose was for an acute release of HTO in 1954. For this release, the dose that could not have been exceeded was estimated to have been 2 mSv (200 mrem), although, because of the high uncertainty about the predictions, the likely dose may have been as low as 360 {micro}Sv (36 mrem) or less. The estimated maximum exposures from the accidental releases were such that no adverse health effects would be expected. Appendix A lists all accidents and large routine puff releases that have occurred at LLNL and SNL/CA between 1953 and 2005. Appendix B describes the processes unique to tritium that must be modeled after an acute release, some of the time-dependent tritium models being used today, and the results of tests of these models.

Evaluation on the harm effects of accidental releases from cryo-compressed hydrogen tank for fuel cell cars  

Science Journals Connector (OSTI)

Abstract Cryogenic compressed hydrogen tank may open new possibilities for onboard storage due to its high energy density and acceptable thermal endurance. As promising hydrogen storage for commercial use, its hazards need comprehensive investigation. This paper studies the consequences of accidental hydrogen releases from cryo-compressed storage and evaluates the cold effects, thermal effects, and overpressure and missile effects. Two typical storage conditions for a fuel cell car are considered, including driving condition and quasi-venting condition after a long-term of parking. Results show that flash fire and vapor cloud explosion can be considered as the leading consequences. Without ignition, catastrophic rupture may be more dangerous than leakages but with ignition the results may vary for different release diameters. For leakages, quasi-venting condition may be more dangerous than driving condition. However, for catastrophic rupture, the results may be not uniformed but depend on whether and when the hydrogen is ignited. Moreover, the influences of wind velocity and atmospheric pressure are also investigated.

Predictions of PuO{sub 2} and tracer compound release from ISV melts  

SciTech Connect (OSTI)

Two field tests were conducted at the Idaho National Engineering Laboratory (INEL) to assess in situ vitrification (ISV) suitability for long-term stabilization of buried radioactive waste. Both tests contained rare-earth oxide tracers (DY{sub 2}O{sub 3}, Yb{sub 2}O{sub 3}, and Tb{sub 4}O{sub 7}) to simulate the presence of plutonium in the form of PuO{sub 2}. In the first test, Intermediate Field Test (IFT)-l, approximately 4-% release of tracer material occurred during soil melting and associated off-gassing, while essentially nil release was observed for the second experiment (IFT-2) for which off-gassing was much reduced. This report presents an evaluation of the IFT test data in terms of governing release processes. Prediction of tracer release during ISV melting centered on an assessment of three potential transport mechanisms, (a) tracer diffusion through stagnant pool, (b) tracer transport by convective currents, and (c) tracer carry-off by escaping gas bubbles. Analysis indicates that tracer release by escaping gas is the dominant release mechanism, which is consistent with video records of gas bubble escape from the ISV melt surface. Quantitative mass transport predictions were also made for the IFT-I test conditions, indicating similarity between the 4-% release data and calculational results at viscosities of {approx} poise and tracer diffusivities of {approx}10{sub {minus}6} CM{sup 2}/s. Since PuO{sub 2} has similar chemical and transport (diffusivity) properties as the rare-earth tracers used in the rare earth tracers used in the IFT experiments, release of PuO{sub 2} is predicted for similar off-gassing conditions. Reduced off-gassing during ISV would thus be expected to improve the overall retention of heavy-oxides within vitrified soil.

Combustion Characteristics and Heat Release Analysis of a Spark-Ignited Engine Fueled with Natural Gas?Hydrogen Blends  

Science Journals Connector (OSTI)

It can be seen that the laminar-burning velocity of hydrogen is 5 times that of natural gas and that the quenching distance of hydrogen is one-third that of natural gas, while the latter is beneficial to reduce the unburned hydrocarbons near the wall and from the top-land crevice. ... The signal of cylinder pressure was acquired for every 0.5 deg CA, the acquisition process covered 254 completed cycles, and the averaged value of these 254 cycles was outputted as the pressure data for calculation of the combustion parameters. ... Two factors are considered to influence the cylinder pressure:? one is the increase in flame propagation speed or combustion speed with the increase of the hydrogen fraction in the blends, and this will cause a rapid rising in the cylinder pressure and bring a higher value of the peak cylinder pressure; another is the decrease in the heating value of the fuel blends with the increase of the hydrogen fraction in natural gas?hydrogen blends, and this will decrease the volumetric heat release rate and the cylinder pressure rising, leading to the lower value of the peak cylinder pressure. ...

NREL: Learning - Hydrogen Production  

Broader source: All U.S. Department of Energy (DOE) Office Webpages (Extended Search)

Production Production The simplest and most common element, hydrogen is all around us, but always as a compound with other elements. To make it usable in fuel cells or otherwise provide energy, we must expend energy or modify another energy source to extract it from the fossil fuel, biomass, water, or other compound in which it is found. Nearly all hydrogen production in the United States today is by steam reformation of natural gas. This, however, releases carbon dioxide in the process and trades one relatively clean fuel for another, with associated energy loss, so it does little to meet national energy needs. Hydrogen can also be produced by electrolysis-passing an electrical current through water to break it into hydrogen and oxygen-but electrolysis is inefficient and is only as clean

Electrochemical hydrogen Storage Systems  

SciTech Connect (OSTI)

As the global need for energy increases, scientists and engineers have found a possible solution by using hydrogen to power our world. Although hydrogen can be combusted as a fuel, it is considered an energy carrier for use in fuel cells wherein it is consumed (oxidized) without the production of greenhouse gases and produces electrical energy with high efficiency. Chemical storage of hydrogen involves release of hydrogen in a controlled manner from materials in which the hydrogen is covalently bound. Sodium borohydride and aminoborane are two materials given consideration as chemical hydrogen storage materials by the US Department of Energy. A very significant barrier to adoption of these materials as hydrogen carriers is their regeneration from 'spent fuel,' i.e., the material remaining after discharge of hydrogen. The U.S. Department of Energy (DOE) formed a Center of Excellence for Chemical Hydrogen Storage, and this work stems from that project. The DOE has identified boron hydrides as being the main compounds of interest as hydrogen storage materials. The various boron hydrides are then oxidized to release their hydrogen, thereby forming a 'spent fuel' in the form of a lower boron hydride or even a boron oxide. The ultimate goal of this project is to take the oxidized boron hydrides as the spent fuel and hydrogenate them back to their original form so they can be used again as a fuel. Thus this research is essentially a boron hydride recycling project. In this report, research directed at regeneration of sodium borohydride and aminoborane is described. For sodium borohydride, electrochemical reduction of boric acid and sodium metaborate (representing spent fuel) in alkaline, aqueous solution has been investigated. Similarly to literature reports (primarily patents), a variety of cathode materials were tried in these experiments. Additionally, approaches directed at overcoming electrostatic repulsion of borate anion from the cathode, not described in the previous literature for electrochemical reduction of spent fuels, have been attempted. A quantitative analytical method for measuring the concentration of sodium borohydride in alkaline aqueous solution has been developed as part of this work and is described herein. Finally, findings from stability tests for sodium borohydride in aqueous solutions of several different compositions are reported. For aminoborane, other research institutes have developed regeneration schemes involving tributyltin hydride. In this report, electrochemical reduction experiments attempting to regenerate tributyltin hydride from tributyltin chloride (a representative by-product of the regeneration scheme) are described. These experiments were performed in the non-aqueous solvents acetonitrile and 1,2-dimethoxyethane. A non-aqueous reference electrode for electrolysis experiments in acetonitrile was developed and is described. One class of boron hydrides, called polyhedral boranes, became of interest to the DOE due to their ability to contain a sufficient amount of hydrogen to meet program goals and because of their physical and chemical safety attributes. Unfortunately, the research performed here has shown that polyhedral boranes do not react in such a way as to allow enough hydrogen to be released, nor do they appear to undergo hydrogenation from the spent fuel form back to the original hydride. After the polyhedral boranes were investigated, the project goals remained the same but the hydrogen storage material was switched by the DOE to ammonia borane. Ammonia borane was found to undergo an irreversible hydrogen release process, so a direct hydrogenation was not able to occur. To achieve the hydrogenation of the spent ammonia borane fuel, an indirect hydrogenation reaction is possible by using compounds called organotin hydrides. In this process, the organotin hydrides will hydrogenate the spent ammonia borane fuel at the cost of their own oxidation, which forms organotin halides. To enable a closed-loop cycle, our task was then to be able to hydrogenate the organotin halides back to th

Study on capacity optimization of PEM fuel cell and hydrogen mixing gas-engine compound generator  

Science Journals Connector (OSTI)

Development of a small-scale power source not dependent on commercial power may result in various effects. For example, it may eliminate the need for long distance power-transmission lines, and mean that the amount of green energy development is not restricted to the dynamic characteristics of a commercial power grid. Moreover, the distribution of the independent energy source can be optimized with regionality in mind. This paper examines the independent power supply system relating to hydrogen energy. Generally speaking, the power demand of a house tends to fluctuate considerably over the course of a day. Therefore, when introducing fuel cell cogeneration into an apartment house, etc., low-efficiency operations in a low-load region occur frequently in accordance with load fluctuation. Consequently, the hybrid cogeneration system (HCGS) that uses a solid polymer membrane-type fuel cell (PEM-FC) and a hydrogen mixture gas engine (NEG) together to improve power generation efficiency during partial load of fuel cell cogeneration is proposed. However, since facility costs increase, if the HCGS energy cost is not low compared with the conventional method, it is disadvantageous. Therefore, in this paper, HCGS is introduced into 10 household apartments in Tokyo, and the power generation efficiency, carbon dioxide emissions and optimal capacity of a boiler and heat storage tank are investigated through analysis. Moreover, the system characteristics change significantly based on the capacity of PEM-FC and NEG that compose HCGS. Therefore, in this study, the capacity of PEM-FC and that of NEG are investigated, as well as the power generation efficiency, carbon dioxide emissions and the optimal capacity of a boiler and heat storage tank. Analysis revealed that the annual average power generation efficiency when the capacity of PEM-FC and NEG is 5kW was 27.3%. Meanwhile, the annual average power generation efficiency of HCGS is 1.37 times that of the PEM-FC independent system, and 1.28 times that of the NEG independent system, respectively.

High pressure/high temperature vapor liquid equilibrium study of light gases in hydrogen-coal liquid model compound systems using perturbation chromatography  

SciTech Connect (OSTI)

Perturbation chromatography or gas-liquid partition chromatography (GLPC) provides a powerful tool for making physicochemical measurements. In this investigation GLPC was applied to study the vapor-liquid equilibrium behavior of light gases in nonvolatile coal liquid model compound solvents at high temperatures and high pressures. Improvements made in existing GLPC techniques include: the use of a high pressure tandem proportioning pump to give precise control of the carrier gas flow rate and low pressure drops; a high pressure ionization chamber to detect the injection of very dilute radioactive sample gases; and the use of a microcomputer to provide instantaneous integration and very precise retention times of the chromatographic peaks. Infinite dilution K-values for methane, ethane, propane, n-butane, carbon dioxide, and hydrogen sulfide in hydrogen-dibenzofuran systems were obtained at 100 and 125 C and up to 800 psia. Infinite dilution K-values for the same light gases in hydrogen-9-methylanthracene systems were obtained at 100, 125, 150, 175, and 200 C and up to 3000 psia. Henry's constants were determined for the light gases in 9-methylanthracene. Second cross virial coefficients and vapor phase infinite dilution fugacity coefficients were calculated for methane, ethane, propane, and n-butane in hydrogen. These results were combined with the experimental K-value measurements to obtain Henry's constants in hydrogen-9-methylanthracene mixtures of fixed liquid compositions. Infinite dilution heats of solution of the solute gases in the mixtures were calculated.

Storing Hydrogen, by Enhancing Diamond Powder Properties under Hydrogen Plasma with CaF2 and KF for Use in Fuel Cells  

Science Journals Connector (OSTI)

A fuel cell is like a battery that instead of using electricity to recharge itself it uses hydrogen. In the fuel cell industry one of the main problems is storing hydrogen in a safe way and extracting it economically. Gaseous hydrogen requires high pressures which could be very dangerous in case of a collision. The success of hydrogen use depends largely on the development of an efficient storage and release method. In an effort to develop a better hydrogen storage system for fuel cells technology this research investigates the use of 99% pure diamond powder for storing hydrogen. Mixing this powder with a calcium fluoride and potassium fluoride compound in its solid form and treating the surface of the powder with hydrogen plasma modifies the surface of the diamond. After some filtration through distilled water and drying the modified diamond is treated with hydrogen. We expect hydrogen to be attracted to the diamond powder surface in higher quantities due to the CaF2 and KF treatment. Due to the large surface area of diamond nanopowder and the electronegative terminal bonds of the fluorine particles on the structures surface to the method shows promise in storing high densities of hydrogen.

1/12-Scale mixing interface visualization and buoyant particle release tests in support of Tank 241-SY-101 hydrogen mitigation  

SciTech Connect (OSTI)

In support of tank waste safety programs, visualization tests were performed in the 1/12-scale tank facility, using a low-viscosity simulant. The primary objective of the tests was to obtain video records of the transient jet-sludge interaction. The intent is that these videos will provide useful qualitative data for comparison with model predictions. Two tests were initially planned: mixing interface visualization (MIV) and buoyant particle release (BPR). Completion of the buoyant particle release test was set aside in order to complete additional MIV tests. Rheological measurements were made on simulant samples before testing, and the simulant was found to exhibit thixotropic behavior. Shear vane measurements were also made on an in-situ analog of the 1/12-scale tank simulant. Simulant shear strength has been observed to be time dependent. The primary objective of obtaining video records of jet-sludge interaction was satisfied, and the records yielded jet location information which may be of use in completing model comparisons. The modeling effort is not part of this task, but this report also discusses test specific instrumentation, visualization techniques, and shear vane instrumentation which would enable improved characterization of jet-sludge interaction and simulant characteristics.

Hydrogen-storing hydride complexes  

DOE Patents [OSTI]

A ternary hydrogen storage system having a constant stoichiometric molar ratio of LiNH.sub.2:MgH.sub.2:LiBH.sub.4 of 2:1:1. It was found that the incorporation of MgH.sub.2 particles of approximately 10 nm to 20 nm exhibit a lower initial hydrogen release temperature of 150.degree. C. Furthermore, it is observed that the particle size of LiBNH quaternary hydride has a significant effect on the hydrogen sorption concentration with an optimum size of 28 nm. The as-synthesized hydrides exhibit two main hydrogen release temperatures, one around 160.degree. C. and the other around 300.degree. C., with the main hydrogen release temperature reduced from 310.degree. C. to 270.degree. C., while hydrogen is first reversibly released at temperatures as low as 150.degree. C. with a total hydrogen capacity of 6 wt. % to 8 wt. %. Detailed thermal, capacity, structural and microstructural properties have been demonstrated and correlated with the activation energies of these materials.

The samples were characterised by X-ray diffraction and surface area determination. The crystalline samples are capable of the intercalation of sodium and lithium ions from solution. Above a temperature of about 500 {sup o}C, in dependence on the oxygen partial pressure a reversible release and uptake of oxygen without a structural variation takes place. The catalytic properties have been evaluated for the oxidative dehydrogenation (ODH) of propane and propene. There are only small differences in the catalytic activity of the different crystalline samples. Because of the relative high starting temperature, a selective catalytic oxidation of propane to propene is hardly observed.

Hydrogen & Fuel Cells - Hydrogen - Hydrogen Quality  

Broader source: All U.S. Department of Energy (DOE) Office Webpages (Extended Search)

Hydrogen Quality Issues for Fuel Cell Vehicles Hydrogen Quality Issues for Fuel Cell Vehicles Introduction Developing and implementing fuel quality specifications for hydrogen are prerequisites to the widespread deployment of hydrogen-fueled fuel cell vehicles. Several organizations are addressing this fuel quality issue, including the International Standards Organization (ISO), the Society of Automotive Engineers (SAE), the California Fuel Cell Partnership (CaFCP), and the New Energy and Industrial Technology Development Organization (NEDO)/Japan Automobile Research Institute (JARI). All of their activities, however, have focused on the deleterious effects of specific contaminants on the automotive fuel cell or on-board hydrogen storage systems. While it is possible for the energy industry to provide extremely pure hydrogen, such hydrogen could entail excessive costs. The objective of our task is to develop a process whereby the hydrogen quality requirements may be determined based on life-cycle costs of the complete hydrogen fuel cell vehicle "system." To accomplish this objective, the influence of different contaminants and their concentrations in fuel hydrogen on the life-cycle costs of hydrogen production, purification, use in fuel cells, and hydrogen analysis and quality verification are being assessed.

Hydrogenation apparatus  

DOE Patents [OSTI]

Hydrogenation reaction apparatus is described comprising a housing having walls which define a reaction zone and conduits for introducing streams of hydrogen and oxygen into the reaction zone, the oxygen being introduced into a central portion of the hydrogen stream to maintain a boundary layer of hydrogen along the walls of the reaction zone. A portion of the hydrogen and all of the oxygen react to produce a heated gas stream having a temperature within the range of from 1,100 to 1,900 C, while the boundary layer of hydrogen maintains the wall temperature at a substantially lower temperature. The heated gas stream is introduced into a hydrogenation reaction zone and provides the source of heat and hydrogen for a hydrogenation reaction. There also is provided means for quenching the products of the hydrogenation reaction. The present invention is particularly suitable for the hydrogenation of low-value solid carbonaceous materials to provide high yields of more valuable liquid and gaseous products. 2 figs.

INSENSITIVE HIGH-NITROGEN COMPOUNDS  

SciTech Connect (OSTI)

The conventional approach to developing energetic molecules is to chemically place one or more nitro groups onto a carbon skeleton, which is why the term ''nitration'' is synonymous to explosives preparation. The nitro group carries the oxygen that reacts with the skeletal carbon and hydrogen fuels, which in turn produces the heat and gaseous reaction products necessary for driving an explosive shock. These nitro-containing energetic molecules typically have heats of formation near zero and therefore most of the released energy is derived from the combustion process. Our investigation of the tetrazine, furazan and tetrazole ring systems has offered a different approach to explosives development, where a significant amount of the chemical potential energy is derived from their large positive heats of formation. Because these compounds often contain a large percentage of nitrogen atoms, they are usually regarded as high-nitrogen fuels or explosives. A general artifact of these high-nitrogen compounds is that they are less sensitive to initiation (e.g. by impact) when compared to traditional nitro-containing explosives of similar performances. Using the precursor, 3,6-bis-(3,5-dimethylpyrazol-1-yl)-s-tetrazine, several useful energetic compounds based on the s-tetrazine system have been synthesized and studied. Some of the first compounds are 3,6-diamino-s-tetrazine-1,4-dioxide (LAX-112) and 3,6-dihydrazino-s-tetrazine (DHT). LAX-112 was once extensively studied as an insensitive explosive by Los Alamos; DHT is an example of a high-nitrogen explosive that relies entirely on its heat of formation for sustaining a detonation. Recent synthesis efforts have yielded an azo-s-tetrazine, 3,3'-azobis(6-amino-s-tetrazine) or DAAT, which has a very high positive heat of formation. The compounds, 4,4'-diamino-3,3'-azoxyfurazan (DAAF) and 4,4'-diamino-3,3'-azofurazan (DAAzF), may have important future roles in insensitive explosive applications. Neither DAAF nor DAAzF can be initiated by laboratory impact drop tests, yet both have in some aspects better explosive performances than 1,3,5-triamino-2,4,6-trinitrobenzene TATB--the standard of insensitive high explosives. The thermal stability of DAAzF is equal to that of hexanitrostilbene (HNS), yet it too is a better explosive performer. The recently discovered tetrazol derivative, 3,6-bis-(1H-1,2,3,4-tetrazol-5-ylamino)-s-tetrazine (BTATz) was measured to have exceptional positive heats of formation and to be insensitive to explosive initiation. Because of its high burn rate with low sensitivity to pressure, this material is of great interest to the propellant community.

Hydrides for Hydrides for Hydrogen Storage George Thomas, Consultant Sandia National Laboratories G. J. Thomas Efficient onboard hydrogen storage is a critical enabling technology for the use of hydrogen in vehicles * The low volumetric density of gaseous fuels requires a storage method which densifies the fuel. - This is particularly true for hydrogen because of its lower energy density relative to hydrocarbon fuels. * Storage methods result in additional weight and volume above that of the fuel. How do we achieve adequate stored energy in an efficient, safe and cost-effective system? G. J.

MODELING ATMOSPHERIC RELEASES OF TRITIUM FROM NUCLEAR INSTALLATIONS  

SciTech Connect (OSTI)

Tritium source term analysis and the subsequent dispersion and consequence analyses supporting the safety documentation of Department of Energy nuclear facilities are especially sensitive to the applied software analysis methodology, input data and user assumptions. Three sequential areas in tritium accident analysis are examined in this study to illustrate where the analyst should exercise caution. Included are: (1) the development of a tritium oxide source term; (2) use of a full tritium dispersion model based on site-specific information to determine an appropriate deposition scaling factor for use in more simplified, broader modeling, and (3) derivation of a special tritium compound (STC) dose conversion factor for consequence analysis, consistent with the nature of the originating source material. It is recommended that unless supporting, defensible evidence is available to the contrary, the tritium release analyses should assume tritium oxide as the species released (or chemically transformed under accident's environment). Important exceptions include STC situations and laboratory-scale releases of hydrogen gas. In the modeling of the environmental transport, a full phenomenology model suggests that a deposition velocity of 0.5 cm/s is an appropriate value for environmental features of the Savannah River Site. This value is bounding for certain situations but non-conservative compared to the full model in others. Care should be exercised in choosing other factors such as the exposure time and the resuspension factor.

Morphology of Gas Release in Physical Simulants  

SciTech Connect (OSTI)

This report documents testing activities conducted as part of the Deep Sludge Gas Release Event Project (DSGREP). The testing described in this report focused on evaluating the potential retention and release mechanisms of hydrogen bubbles in underground radioactive waste storage tanks at Hanford. The goal of the testing was to evaluate the rate, extent, and morphology of gas release events in simulant materials. Previous, undocumented scoping tests have evidenced dramatically different gas release behavior from simulants with similar physical properties. Specifically, previous gas release tests have evaluated the extent of release of 30 Pa kaolin and 30 Pa bentonite clay slurries. While both materials are clays and both have equivalent material shear strength using a shear vane, it was found that upon stirring, gas was released immediately and completely from bentonite clay slurry while little if any gas was released from the kaolin slurry. The motivation for the current work is to replicate these tests in a controlled quality test environment and to evaluate the release behavior for another simulant used in DSGREP testing. Three simulant materials were evaluated: 1) a 30 Pa kaolin clay slurry, 2) a 30 Pa bentonite clay slurry, and 3) Rayleigh-Taylor (RT) Simulant (a simulant designed to support DSGREP RT instability testing. Entrained gas was generated in these simulant materials using two methods: 1) application of vacuum over about a 1-minute period to nucleate dissolved gas within the simulant and 2) addition of hydrogen peroxide to generate gas by peroxide decomposition in the simulants over about a 16-hour period. Bubble release was effected by vibrating the test material using an external vibrating table. When testing with hydrogen peroxide, gas release was also accomplished by stirring of the simulant.

A carboxylic-intercalated graphite compound composition for the production of exfoliated graphite, flexible graphite, or nano-scaled graphene platelets. The composition comprises a layered graphite with interlayer spaces or interstices and a carboxylic acid residing in at least one of the interstices, wherein the composition is prepared by a chemical oxidation reaction which uses a combination of a carboxylic acid and hydrogen peroxide as an intercalate source. Alternatively, the composition may be prepared by an electrochemical reaction, which uses a carboxylic acid as both an electrolyte and an intercalate source. Exfoliation of the invented composition does not release undesirable chemical contaminants into air or drainage.

Hydrogen Storage Systems Modeling and Analysis Hydrogen Storage Systems Modeling and Analysis Several different approaches are being pursued to develop on-board hydrogen storage systems for light-duty vehicle applications. The different approaches have different characteristics, such as: the thermal energy and temperature of charge and discharge kinetics of the physical and chemical process steps involved requirements for the materials and energy interfaces between the storage system and the fuel supply system on one hand, and the fuel user on the other Other storage system design and operating parameters influence the projected system costs as well. Argonne researchers are developing thermodynamic, kinetic, and engineering models of the various hydrogen storage systems to understand the characteristics of storage systems based on these approaches and to evaluate their potential to meet the DOE targets for on-board applications. The DOE targets for 2015 include a system gravimetric capacity of 1.8 kWh/kg (5.5 wt%) and a system volumetric capacity of 1.3 kWh/L (40 g/L). We then use these models to identify significant component and performance issues, and evaluate alternative system configurations and design and operating parameters.

The ability of atomic hydrogen to chemisorb on graphene makes the latter a promising material for hydrogen storage. Based on scanning tunneling microscopy techniques, we report on site-selective adsorption of atomic hydrogen on convexly curved regions of monolayer graphene grown on SiC(0001). This system exhibits an intrinsic curvature owing to the interaction with the substrate. We show that at low coverage hydrogen is found on convex areas of the graphene lattice. No hydrogen is detected on concave regions. These findings are in agreement with theoretical models which suggest that both binding energy and adsorption barrier can be tuned by controlling the local curvature of the graphene lattice. This curvature-dependence combined with the known graphene flexibility may be exploited for storage and controlled release of hydrogen at room temperature making it a valuable candidate for the implementation of hydrogen-storage devices.

Active Hydrogen  

Science Journals Connector (OSTI)

Dry hydrogen can be activated in an electric discharge if the pressure and voltage are carefully regulated. Active hydrogen reduces metallic sulphides whose heat of formation is 22 000 cal. or less. The active gas is decomposed by 3 cm of well packed glass wool. A quantitative method is given for the determination of active hydrogen. Less of the active gas is formed in a tube coated with stearic acid or phosphoric acid than when no coating is employed. The decay reaction was found to follow the expression for a unimolecular reaction. The rate of decay appears to be independent of the wall surface. The period of half?life at room temperature and 40 mm pressure is 0.2 sec. approximately. The energy of formation of active hydrogen is approximately 18 000 cal. The energy of activation for the decay of the active constituent is approximately 17 800 cal. The properties of active hydrogen are considered in relation to the properties predicted for H3.

Method and apparatus for controlling accidental releases of tritium  

DOE Patents [OSTI]

An improvement is described in a tritium control system based on a catalytic oxidation reactor wherein accidental releases of tritium into room air are controlled by flooding the catalytic oxidation reactor with hydrogen when the tritium concentration in the room air exceeds a specified limit. The sudden flooding with hydrogen heats the catalyst to a high temperature within seconds, thereby greatly increasing the catalytic oxidation rate of tritium to tritiated water vapor. Thus, the catalyst is heated only when needed. In addition to the heating effect, the hydrogen flow also swamps the tritium and further reduces the tritium release. 1 fig.

Furthermore, it is observed that the particle size of LiBNH quaternary hydride has a significant effect on the hydrogen sorption concentration with an optimum size of 28 nm. The as-synthesized hydrides exhibit two main hydrogen release temperatures, one around 160.degree. C. and the other around 300.degree. C., with the main hydrogen release temperature reduced from 310.degree. C. to 270.degree. C., while hydrogen is first reversibly released at temperatures as low as 150.degree.

Electrochemical Hydrogen Compressor  

SciTech Connect (OSTI)

The Electrochemical Hydrogen Compressor EHC was evaluated against DOE applications for compressing hydrogen at automobile filling stations, in future hydrogen pipelines and as a commercial replacement for conventional diaphragm hydrogen compressors. It was also evaluated as a modular replacement for the compressors used in petrochemical refineries. If the EHC can be made inexpensive, reliable and long lived then it can satisfy all these applications save pipelines where the requirements for platinum catalyst exceeds the annual world production. The research performed did not completely investigate Molybdenum as a hydrogen anode or cathode, it did show that photoetched 316 stainless steel is inadequate for an EHC. It also showed that: molybdenum bipolar plates, photochemical etching processes, and Gortex Teflon seals are too costly for a commercial EHC. The use of carbon paper in combination with a perforated thin metal electrode demonstrated adequate anode support strength, but is suspect in promoting galvanic corrosion. The nature of the corrosion mechanisms are not well understood, but locally high potentials within the unit cell package are probably involved. The program produced a design with an extraordinary high cell pitch, and a very low part count. This is one of the promising aspects of the redesigned EHC. The development and successful demonstration of the hydraulic cathode is also important. The problem of corrosion resistant metal bipolar plates is vital to the development of an inexpensive, commercial PEM fuel cell. Our research suggests that there is more to the corrosion process in fuel cells and electrochemical compressors than simple, steady state, galvanic stability. It is an important area for scientific investigation. The experiments and analysis conducted lead to several recommended future research directions. First, we need a better understanding of the corrosion mechanisms involved. The diagnosis of experimental cells with titration to determine the loss of membrane active sites is recommended. We suspect that the corrosion includes more than simple galvanic mechanisms. The mechanisms involved in this phenomenon are poorly understood. Shunt currents at hydraulic cathode ports were problematic, but are not difficult to cure. In addition to corrosion there is evidence of high component resistivity. This may be due to the deposition of organic compounds, which may be produced electrochemically on the surface of the metal support screens that contact carbon gas diffusion layers (GDLs) or catalyst supports. An investigation of possible electro-organic sythesis mechanisms with emphasis on oxalates formation is warranted. The contaminated cell parts can be placed in an oxidizing atmosphere at high temperature and the weight loss can be observed. This would reveal the existence of organic compounds. Investigation into the effects of conductivity enhancers such as carbon microlayers on supporting carbon paper is also needed. Corrosion solutions should be investigated such as surface passivation of 316 SS parts using nitric acid. Ultra thin silane/siloxane polymer coatings should be tried. These may be especially useful in conjunction with metal felt replacement of carbon paper. A simple cure for the very high, localized corrosion of the anode might be to diffusion bond the metal electrode support screen to bipolar plate. This will insure uniform resistance perpendicular to the plane of the cell and eliminate some of the dependence of the resistance on high stack compression. Alternative materials should be explored. Alternatives to carbon in the cell may be helpful in any context. In particular, alternatives to carbon paper GDLs such as metal felts and alternatives to carbon supports for Pt such as TiC and TiB2 might also be worthwhile and would be helpful to fuel cells as well. Some alternative to the metals we used in the cell, Mo and 316 SS, are potentially useful. These include Al/Mg/Si alloys. Corrosion resistant materials such as Nb and Mo might prove useful as cladding materials that can be hot stamp

Hydrogen Permeation Barrier Coatings  

SciTech Connect (OSTI)

Gaseous hydrogen, H2, has many physical properties that allow it to move rapidly into and through materials, which causes problems in keeping hydrogen from materials that are sensitive to hydrogen-induced degradation. Hydrogen molecules are the smallest diatomic molecules, with a molecular radius of about 37 x 10-12 m and the hydrogen atom is smaller still. Since it is small and light it is easily transported within materials by diffusion processes. The process of hydrogen entering and transporting through a materials is generally known as permeation and this section reviews the development of hydrogen permeation barriers and barrier coatings for the upcoming hydrogen economy.

Chemical Hydrides for Hydrogen Storage in Fuel Cell Applications  

SciTech Connect (OSTI)

Due to its high hydrogen storage capacity (up to 19.6% by weight for the release of 2.5 molar equivalents of hydrogen gas) and its stability under typical ambient conditions, ammonia borane (AB) is a promising material for chemical hydrogen storage for fuel cell applications in transportation sector. Several systems models for chemical hydride materials such as solid AB, liquid AB and alane were developed and evaluated at PNNL to determine an optimal configuration that would meet the 2010 and future DOE targets for hydrogen storage. This paper presents an overview of those systems models and discusses the simulation results for various transient drive cycle scenarios.

Stations Stations Public-use hydrogen fueling stations are very much like gasoline ones. In fact, sometimes, hydrogen and gasoline cars can be fueled at the same station. These stations offer self-service pumps, convenience stores, and other services in high-traffic locations. Photo of a Shell fueling station showing the site convenience store and hydrogen and gasoline fuel pumps. This fueling station in Washington, D.C., provides drivers with both hydrogen and gasoline fuels Many future hydrogen fueling stations will be expansions of existing fueling stations. These facilities will offer hydrogen pumps in addition to gasoline or natural gas pumps. Other hydrogen fueling stations will be "standalone" operations. These stations will be designed and constructed to

Progress in donor assisted coal liquefaction: Hydroaromatic compound formation  

SciTech Connect (OSTI)

The role of hydrogen donor compounds in coal liquefaction has been extensively investigated since the mid 1960`s using model compounds and process derived hydrogen donor solvents. Our recent research and that of other investigators have shown that two model compounds in particular have great efficacy in solvating low rank coals. 1,2,3,10b tetrahydrofluoranthene (H{sub 4}Fl) and 1,2,3,6,7,8 hexahydropyrene (H{sub 6}Py) have been used to dissolve Wyodak coal to > 95% soluble material as measured by tetrahydrofuran (THF). Although these hydrogen donors are very effective, they may not be found in any significant concentrations in actual liquefaction process recycle solvents. Therefore, studies with process derived recycle materials are necessary to understand donor solvent chemistry. The objective of this paper is to present results of solvent hydrogenation experiments using heavy distillate solvents produced during testing at the Wilsonville Advanced Coal Liquefaction Test Facility. We evaluated the impact of hydrogenation conditions upon hydrogen donor formation in process derived distillates and compared these process derived solvents with the highly effective H{sub 4}Fl and H{sub 6}Py donors in coal liquefaction tests. This paper presents data on reaction conditions used for distillate hydrotreating and subsequent coal liquefaction, with an aim toward understanding the relationship between reaction conditions and donor solvent quality in recycle distillates.

Molecular models for the intercalation of hydrogen molecules into modified graphites  

SciTech Connect (OSTI)

Carbonized aerogels have been proposed as a medium for the storage of H{sub 2} gas. Quantum chemical calculations were performed on a series of substituted polyaromatic ring compounds. Parallel ``sandwiches`` of these compounds were used as a model of graphite. Hydrogen was introduced between the compounds as a model of H{sub 2} intercalated into graphite. It was found that it required work to insert the H{sub 2} into most of the compounds, except when the presence of the hydrogen allowed the compound to find a new configuration with a lower energy.

Hydrogen storage composition and method  

DOE Patents [OSTI]

A hydrogen storage composition based on a metal hydride dispersed in an aerogel prepared by a sol-gel process. The starting material for the aerogel is an organometallic compound, including the alkoxysilanes, organometals of the form M(OR)x and MOxRy, where R is an alkyl group of the form C.sub.n H.sub.2n+1, M is an oxide-forming metal, n, x, and y are integers, and y is two less than the valence of M. A sol is prepared by combining the starting material, alcohol, water, and an acid. The sol is conditioned to the proper viscosity and a hydride in the form of a fine powder is added. The mixture is polymerized and dried under supercritical conditions. The final product is a composition having a hydride uniformly dispersed throughout an inert, stable and highly porous matrix. It is capable of absorbing up to 30 moles of hydrogen per kilogram at room temperature and pressure, rapidly and reversibly. Hydrogen absorbed by the composition can be readily be recovered by heat or evacuation.

The objectives of this project, covering two phases and an additional extension phase, were the development of thin film-based hybrid photovoltaic (PV)/photoelectrochemical (PEC) devices for solar-powered water splitting. The hybrid device, comprising a low-cost photoactive material integrated with amorphous silicon (a-Si:H or a-Si in short)-based solar cells as a driver, should be able to produce hydrogen with a 5% solar-to-hydrogen conversion efficiency (STH) and be durable for at least 500 hours. Three thin film material classes were studied and developed under this program: silicon-based compounds, copper chalcopyrite-based compounds, and metal oxides. With the silicon-based compounds, more specifically the amorphous silicon carbide (a-SiC), we achieved a STH efficiency of 3.7% when the photoelectrode was coupled to an a-Si tandem solar cell, and a STH efficiency of 6.1% when using a crystalline Si PV driver. The hybrid PV/a-SiC device tested under a current bias of -3~4 mA/cm{sup 2}, exhibited a durability of up to ~800 hours in 0.25 M H{sub 2}SO{sub 4} electrolyte. Other than the PV driver, the most critical element affecting the photocurrent (and hence the STH efficiency) of the hybrid PV/a-SiC device was the surface energetics at the a-SiC/electrolyte interface. Without surface modification, the photocurrent of the hybrid PEC device was ~1 mA/cm{sup 2} or lower due to a surface barrier that limits the extraction of photogenerated carriers. We conducted an extensive search for suitable surface modification techniques/materials, of which the deposition of low work function metal nanoparticles was the most successful. Metal nanoparticles of ruthenium (Ru), tungsten (W) or titanium (Ti) led to an anodic shift in the onset potential. We have also been able to develop hybrid devices of various configurations in a monolithic fashion and optimized the current matching via altering the energy bandgap and thickness of each constituent cell. As a result, the short-circuit photocurrent density of the hybrid device (measured in a 2-electrode configuration) increased significantly without assistance of any external bias, i.e. from ?1 mA/cm{sup 2} to ~5 mA/cm{sup 2}. With the copper chalcopyrite compounds, we have achieved a STH efficiency of 3.7% in a coplanar configuration with 3 a-Si solar cells and one CuGaSe{sub 2} photocathode. This material class exhibited good durability at a photocurrent density level of -4 mA/cm{sup 2} (5% STH equivalent) at a fixed potential (-0.45 VRHE). A poor band-edge alignment with the hydrogen evolution reaction (HER) potential was identified as the main limitation for high STH efficiency. Three new pathways have been identified to solve this issue. First, PV driver with bandgap lower than that of amorphous silicon were investigated. Crystalline silicon was identified as possible bottom cell. Mechanical stacks made with one Si solar cell and one CuGaSe{sub 2} photocathode were built. A 400 mV anodic shift was observed with the Si cell, leading to photocurrent density of -5 mA/cm{sup 2} at 0VRHE (compared to 0 mA/cm{sup 2} at the same potential without PV driver). We also investigated the use of p-n junctions to shift CuGaSe{sub 2} flatband potential anodically. Reactively sputtered zinc oxy-sulfide thin films was evaluated as n-type buffer and deposited on CuGaSe{sub 2}. Ruthenium nanoparticles were then added as HER catalyst. A 250 mV anodic shift was observed with the p-n junction, leading to photocurrent density at 0VRHE of -1.5 mA/cm{sup 2}. Combining this device with a Si solar cell in a mechanical stack configuration shifted the onset potential further (+400 mV anodically), leading to photocurrent density of -7 mA/cm{sup 2} at 0VRHE. Finally, we developed wide bandgap copper chalcopyrite thin film materials. We demonstrated that Se can be substituted with S using a simple annealing step. Photocurrent densities in the 5-6 mA/cm{sub 2} range were obtained with red 2.0eV CuInGaS{sub 2} photocathodes. With the metal oxide compounds, we have demonstrated that a WO{sub 3}-based hybrid p

Hydrogen storage on activated carbon. Final report  

SciTech Connect (OSTI)

The project studied factors that influence the ability of carbon to store hydrogen and developed techniques to enhance that ability in naturally occurring and factory-produced commercial carbon materials. During testing of enhanced materials, levels of hydrogen storage were achieved that compare well with conventional forms of energy storage, including lead-acid batteries, gasoline, and diesel fuel. Using the best materials, an electric car with a modern fuel cell to convert the hydrogen directly to electricity would have a range of over 1,000 miles. This assumes that the total allowable weight of the fuel cell and carbon/hydrogen storage system is no greater than the present weight of batteries in an existing electric vehicle. By comparison, gasoline cars generally are limited to about a 450-mile range, and battery-electric cars to 40 to 60 miles. The project also developed a new class of carbon materials, based on polymers and other organic compounds, in which the best hydrogen-storing factors discovered earlier were {open_quotes}molecularly engineered{close_quotes} into the new materials. It is believed that these new molecularly engineered materials are likely to exceed the performance of the naturally occurring and manufactured carbons seen earlier with respect to hydrogen storage.

Compound cryopump for fusion reactors  

E-Print Network [OSTI]

We reconsider an old idea: a three-stage compound cryopump for use in fusion reactors such as DEMO. The helium "ash" is adsorbed on a 4.5 K charcoal-coated surface, while deuterium and tritium are adsorbed at 15-22 K on a second charcoal-coated surface. The helium is released by raising the first surface to ~30 K. In a separate regeneration step, deuterium and tritium are released at ~110 K. In this way, the helium can be pre-separated from other species. In the simplest design, all three stages are in the same vessel, with a single valve to close the pump off from the tokamak during regeneration. In an alternative design, the three stages are in separate vessels, connected by valves, allowing the stages to regenerate without interfering with each other. The inclusion of the intermediate stage would not affect the overall pumping speed significantly. The downstream exhaust processing system could be scaled down, as much of the deuterium and tritium could be returned directly to the reactor. This could reduce ...

Theoretical Studies of Hydrogen Storage Alloys.  

SciTech Connect (OSTI)

Theoretical calculations were carried out to search for lightweight alloys that can be used to reversibly store hydrogen in mobile applications, such as automobiles. Our primary focus was on magnesium based alloys. While MgH{sub 2} is in many respects a promising hydrogen storage material, there are two serious problems which need to be solved in order to make it useful: (i) the binding energy of the hydrogen atoms in the hydride is too large, causing the release temperature to be too high, and (ii) the diffusion of hydrogen through the hydride is so slow that loading of hydrogen into the metal takes much too long. In the first year of the project, we found that the addition of ca. 15% of aluminum decreases the binding energy to the hydrogen to the target value of 0.25 eV which corresponds to release of 1 bar hydrogen gas at 100 degrees C. Also, the addition of ca. 15% of transition metal atoms, such as Ti or V, reduces the formation energy of interstitial H-atoms making the diffusion of H-atoms through the hydride more than ten orders of magnitude faster at room temperature. In the second year of the project, several calculations of alloys of magnesium with various other transition metals were carried out and systematic trends in stability, hydrogen binding energy and diffusivity established. Some calculations of ternary alloys and their hydrides were also carried out, for example of Mg{sub 6}AlTiH{sub 16}. It was found that the binding energy reduction due to the addition of aluminum and increased diffusivity due to the addition of a transition metal are both effective at the same time. This material would in principle work well for hydrogen storage but it is, unfortunately, unstable with respect to phase separation. A search was made for a ternary alloy of this type where both the alloy and the corresponding hydride are stable. Promising results were obtained by including Zn in the alloy.

Hydrogen peroxide safety issues  

SciTech Connect (OSTI)

A literature survey was conducted to review the safety issues involved in handling hydrogen peroxide solutions. Most of the information found in the literature is not directly applicable to conditions at the Rocky Flats Plant, but one report describes experimental work conducted previously at Rocky Flats to determine decomposition reaction-rate constants for hydrogen peroxide solutions. Data from this report were used to calculate decomposition half-life times for hydrogen peroxide in solutions containing several decomposition catalysts. The information developed from this survey indicates that hydrogen peroxide will undergo both homogeneous and heterogeneous decomposition. The rate of decomposition is affected by temperature and the presence of catalytic agents. Decomposition of hydrogen peroxide is catalyzed by alkalies, strong acids, platinum group and transition metals, and dissolved salts of transition metals. Depending upon conditions, the consequence of a hydrogen peroxide decomposition can range from slow evolution of oxygen gas to a vapor, phase detonation of hydrogen peroxide vapors.

SciTech Connect (OSTI)

The aim of this project is to develop and apply computational materials science tools to determine and predict critical properties of hydrogen storage materials. By better understanding the absorption/desorption mechanisms and characterizing their physical properties it is possible to explore and evaluate new directions for hydrogen storage materials. Particular emphasis is on the determination of the structure and thermodynamics of hydrogen storage materials, the investigation of microscopic mechanisms of hydrogen uptake and release in various materials and the role of catalysts in this process. As a team we have decided to focus on a single material, NaAlH{sub 4}, in order to fully be able to study the many aspects of hydrogen storage. We have focused on phase stability, mass transport and size-dependent reaction mechanisms in this material.

Ultrafine hydrogen storage powders  

DOE Patents [OSTI]

A method of making hydrogen storage powder resistant to fracture in service involves forming a melt having the appropriate composition for the hydrogen storage material, such, for example, LaNi.sub.5 and other AB.sub.5 type materials and AB.sub.5+x materials, where x is from about -2.5 to about +2.5, including x=0, and the melt is gas atomized under conditions of melt temperature and atomizing gas pressure to form generally spherical powder particles. The hydrogen storage powder exhibits improved chemcial homogeneity as a result of rapid solidfication from the melt and small particle size that is more resistant to microcracking during hydrogen absorption/desorption cycling. A hydrogen storage component, such as an electrode for a battery or electrochemical fuel cell, made from the gas atomized hydrogen storage material is resistant to hydrogen degradation upon hydrogen absorption/desorption that occurs for example, during charging/discharging of a battery. Such hydrogen storage components can be made by consolidating and optionally sintering the gas atomized hydrogen storage powder or alternately by shaping the gas atomized powder and a suitable binder to a desired configuration in a mold or die.

Awaiting your repsonse Replies: I'm not quite sure what you mean by hydrogen based bacteria but I will take a stab that you mean bacteria that use hydrogen for energy. Some bacteria are chemolithotrophs which mean that they are autrophs but don't use the sun as their energy source; they get their energy from chemical sources. There are bacteria that use hydrogen as their energy source. They are diverse as a group and are all facultative. The overall chemical reaction looks like this:

Hydrogenation of carbonaceous materials  

DOE Patents [OSTI]

A method for reacting pulverized coal with heated hydrogen-rich gas to form hydrocarbon liquids suitable for conversion to fuels wherein the reaction involves injection of pulverized coal entrained in a minimum amount of gas and mixing the entrained coal at ambient temperature with a separate source of heated hydrogen. In accordance with the present invention, the hydrogen is heated by reacting a small portion of the hydrogen-rich gas with oxygen in a first reaction zone to form a gas stream having a temperature in excess of about 1000.degree. C. and comprising a major amount of hydrogen and a minor amount of water vapor. The coal particles then are reacted with the hydrogen in a second reaction zone downstream of the first reaction zone. The products of reaction may be rapidly quenched as they exit the second reaction zone and are subsequently collected.

Hydrogen Safety Knowledge Tools  

SciTech Connect (OSTI)

With hydrogen gaining acceptance as an energy carrier for fuel cell vehicles and stationary fuel cell applications, a new community of hydrogen users is emerging and continues to grow. With this growth has come the need to spread the word about safe practices for handling, storing, and using hydrogen. Like all energy forms, hydrogen can be used safely through proper procedures and engineering techniques. However, hydrogen involves a degree of risk that must be respected, and the importance of avoiding complacency or haste in the safe conduct and performance of projects involving hydrogen cannot be overstated. To encourage and promote the safe use of hydrogen, Pacific Northwest National Laboratory (PNNL) has developed and continues to enhance two software tools in support of the U.S. Department of Energy's Fuel Cell Technologies Program: the Hydrogen Safety Best Practices online manual (www.H2BestPractices.org) and the Hydrogen Incident Reporting and Lessons Learned database (www.H2Incidents.org).

Thin film hydrogen sensor  

DOE Patents [OSTI]

A hydrogen sensor element comprises an essentially inert, electrically-insulating substrate having a thin-film metallization deposited thereon which forms at least two resistors on the substrate. The metallization comprises a layer of Pd or a Pd alloy for sensing hydrogen and an underlying intermediate metal layer for providing enhanced adhesion of the metallization to the substrate. An essentially inert, electrically insulating, hydrogen impermeable passivation layer covers at least one of the resistors, and at least one of the resistors is left uncovered. The difference in electrical resistances of the covered resistor and the uncovered resistor is related to hydrogen concentration in a gas to which the sensor element is exposed.

The hydrogen economy: Its history  

Science Journals Connector (OSTI)

The concept leading to a hydrogen economy lay in the work of a Nazi engineer, Lawaceck, 1968. I heard his suggestion of cheaper transfer of energy in hydrogen through pipes at a dinner in that year. A paper was published with Appleby in 1972 which was the first published document concerning that title and involving the title of A Hydrogen Economy. The first meeting was in Cornell University in 1973. In 1974 T. Nejat Veziroglu organized the first big meeting on hydrogen (900 attendees). At this meeting I presented privately to Veziroglu the possibilities of a world development and he told me that he was ready to put his organizing ability to use in spreading the ideas worldwide. However, he not only proceeded to do this but he, also a professor at the University of Miami, contributed several papers of notes, particularly the one with Awad of 1974 about the cost of pollution. Gregory worked at the Gas Research Institute from 1971 and confirmed the expectations put down by Lawaceck. Veziroglu founded the International Journal of Hydrogen Energy in 1974. Research in hydrogen was relatively low cost and therefore was taken up most eagerly by those from the newer countries. The National Science Foundation awarded Texas A&M University in 1982 a five year support for hydrogen as a fuel with the condition that half the costs be borne by at least five industrial companies. I was appointed director of the research under the grant and chose to concentrate upon the decomposition of water by solar light via an electrochemical photo fuel cell. We were able to obtain considerable increases in efficiency of decomposition of water by solar light, and at the time the work was interrupted we had 9.6 percent efficiency for decomposition. S.U.M. Khan and R. Kainthla were the principal contributors to the theory of using light via electrochemical cells for this purpose. The Texas A&M University work on hydrogen was interrupted in 1989 by the arrival of claims that one of my former students had carried out electrolysis of deuterium oxide saying that an extra unexplained heat had been observed and he suggested this heat was nuclear in origin. Later, seeking to reduce the cost of hydrogen as a fuel I involved Sol Zaromb in discussions and we came across the idea that if one included a carbon dioxide molecule obtained by removing it from the atmosphere in the structure of methanolAT, no increase in global warming would occur from the use of methanol with that condition, (published in 2008). By this condition methanol took on the largest advantage of gaseous hydrogen: That it did not cause global warming. The estimated cost of the new (anti-global warming) fuel, methanolAT was less than $30/GJ. This estimated cost could be compared with the $48/GJ which is now being supported by a French Canadian group who published an attractive book with six pages of calculations of costs. The difference between the cost estimated by this group and the costs which have been assumed by hydrogen enthusiasts in earlier times was that they took into account the auxiliary expenses which would come with the use of hydrogen, in particular the storage at high pressure. The characteristics of the new methanol to cause no global warming put that aspect of it on an equal footing to the gaseous hydrogen. The CO2 which was an essential part of the structure of methanolAT was necessary to be created in a stream, rather than directly from the atmosphere, but it was easily shown that this could be done by the use of biomass and by carbonaceous wastes. A German team under Weiderman and Grob appeared in 2008 and proceeded to suggest some extensions of the ideas which had been undergoing publication for some time. The aim of the German work was to reduce costs of a compound which they called Methasyn. The present situation is that the claim of methanolAT as a world fuel to be used without any concerns of exhaustion or pollution depends on the commercial point of view of the costs being less than that of obtaining oil from the tar sands.

Bridged transition-metal complexes and uses thereof for hydrogen separation, storage and hydrogenation  

DOE Patents [OSTI]

The present invention constitutes a class of organometallic complexes which reversibly react with hydrogen to form dihydrides and processes by which these compounds can be utilized. The class includes bimetallic complexes in which two cyclopentadienyl rings are bridged together and also separately .pi.-bonded to two transition metal atoms. The transition metals are believed to bond with the hydrogen in forming the dihydride. Transition metals such as Fe, Mn or Co may be employed in the complexes although Cr constitutes the preferred metal. A multiple number of ancilliary ligands such as CO are bonded to the metal atoms in the complexes. Alkyl groups and the like may be substituted on the cyclopentadienyl rings. These organometallic compounds may be used in absorption/desorption systems and in facilitated transport membrane systems for storing and separating out H.sub.2 from mixed gas streams such as the product gas from coal gasification processes.

Plasma post-hydrogenation of hydrogenated amorphous silicon and germanium  

SciTech Connect (OSTI)

Incorporation and kinetics of hydrogen during plasma post-hydrogenation and thermal treatment are discussed for a-Si:H and a-Ge:H films. For material of low hydrogen content, the hydrogen surface concentration reached by plasma treatment equals the hydrogen concentration obtained by deposition at the same temperature and under similar plasma conditions. Enhancements of the hydrogen diffusion coefficient and of hydrogen solubility observed for plasma treatment at temperatures {le}400 C and {le}300 C for a-Si:H and a-Ge:H, respectively, are attributed to a plasma induced rise of the surface hydrogen chemical potential.

Hydrogen Storage Hydrogen Storage On the one hand, hydrogen's great asset as a renewable energy carrier is that it is storable and transportable. On the other hand, its very low natural density requires storage volumes that are impractical for vehicles and many other uses. Current practice is to compress the gas in pressurized tanks, but this still provides only limited driving range for vehicles and is bulkier than desirable for other uses as well. Liquefying the hydrogen more than doubles the fuel density, but uses up substantial amounts of energy to lower the temperature sufficiently (-253°C at atmospheric pressure), requires expensive insulated tanks to maintain that temperature, and still falls short of desired driving range. One possible way to store hydrogen at higher density is in the spaces within the crystalline

For the past 6 years, open discussions and/or meetings have been held and are still on-going with OEM, Hydrogen Suppliers, other test facilities from the North America Team and International collaborators regarding experimental results, fuel clean-up cost, modeling, and analytical techniques to help determine levels of constituents for the development of an international standard for hydrogen fuel quality (ISO TC197 WG-12). Significant progress has been made. The process for the fuel standard is entering final stages as a result of the technical accomplishments. The objectives are to: (1) Determine the allowable levels of hydrogen fuel contaminants in support of the development of science-based international standards for hydrogen fuel quality (ISO TC197 WG-12); and (2) Validate the ASTM test method for determining low levels of non-hydrogen constituents.

Investigation of hydrogen transfer in coprocessing using model systems  

SciTech Connect (OSTI)

The objective of this research was to evaluate the role of the resid in the coprocessing of coal and petroleum resid. The question being asked was whether the resid is an active solvent in coprocessing reactions and whether resid donates any hydrogen to coal during coprocessing. An effective means of determining whether resid participates in the reactions at coprocessing conditions is to use model systems and trace their reaction pathways. The research performed in this study evaluated the hydrogen donability of a naphthenic compound perhydropyrene, a compound type prevalent in resids that are hydrogen-rich. Model species were also used as acceptors that represented the aromatic aspect of coal. The model acceptors that were used were anthracene and phenanthrene.

Charge Density Wave Compounds  

Broader source: All U.S. Department of Energy (DOE) Office Webpages (Extended Search)

Fisher Research Group Fisher Research Group Layered Chalcogenides 29 February 2008 Controlling the Wave by Brad Plummer, SLAC Communications Stanford University researchers working in part at SSRL have discovered a novel set of properties pertaining to a compound of materials called tritellurides. These compounds, composed of three atoms of tellurium and a single atom of one of the rare earth elements, demonstrate unique electronic properties that can be controlled by altering the temperature of the material. The tritellurides display phenomena known as charge density waves (CDW). In a normal conductive metal, electrons persist in a "sea" wherein they are evenly distributed and equally available, or conductive. A CDW occurs under certain circumstances and causes the electrons to clump together, lowering their availability, and thereby lowering the compound's conductivity. Tellurium, when crystallized into quasi-two-dimensional planes and combined with rare earth elements, produces a material with CDWs that can be manipulated and controlled.

Microoptical compound lens  

DOE Patents [OSTI]

An apposition microoptical compound lens comprises a plurality of lenslets arrayed around a segment of a hollow, three-dimensional optical shell. The lenslets collect light from an object and focus the light rays onto the concentric, curved front surface of a coherent fiber bundle. The fiber bundle transports the light rays to a planar detector, forming a plurality of sub-images that can be reconstructed as a full image. The microoptical compound lens can have a small size (millimeters), wide field of view (up to 180.degree.), and adequate resolution for object recognition and tracking.

Prediction of a multicenter-bonded solid boron hydride for hydrogen storage  

Science Journals Connector (OSTI)

A layered solid boron hydride structure (B2H2) consisting of a hexagonal boron network and bridge hydrogen which has a gravimetric capacity of 8wt% hydrogen is predicted. The structural, electronic, and dynamical properties of the proposed structure are investigated using first-principles electronic structure methods. The absence of soft phonon modes confirms the dynamical stability of the proposed structure. Charging the structure significantly softens hydrogen related phonon modes. Boron modes, in contrast, are either hardened or not significantly affected by electron doping. Furthermore, self-doping the structure considerably reduces the energy barrier against hydrogen release. These results suggest that electrochemical charging or self-doping mechanisms may facilitate hydrogen release while the underlying boron network remains intact for subsequent rehydrogenation.

The reaction kinetics of gasoline sulfur compounds: Catalytic mechanisms for sulfur reduction  

SciTech Connect (OSTI)

One of the key elements of reformulated gasoline is the reduction of the sulfur compounds produced by fluid catalytic cracking. This paper probes the reaction kinetics of refractory gasoline-range thiophene derivatives (thiophene, tetrahydrothiophene, and alkylthiophenes) in an effort to determine the mechanisms of sulfur compound cracking in the FCC unit. The gasoline-range sulfur compounds were analyzed using gas chromatography with an atomic emission detector. The authors` results show that the FCC catalysts affects the cracking of sulfur compounds through both hydrogen transfer and zeolite pore restriction mechanisms. An experimental FCC catalyst is shown to reduce gasoline sulfur content in the Davidson Circulating Riser (DCR{sup TM}) pilot unit. Model compound tests show that the activity of the catalyst is due to both its catalytic and adsorptive properties. Tetrahydrothiophene, which is produced from thiophenes by hydrogen transfer, is completely removed by the experimental catalyst.

Standard-D hydrogen monitoring system, system design description  

SciTech Connect (OSTI)

During most of the year, it is assumed that the vapor space in the 177 radioactive waste tanks on the Hanford Project site contain a uniform mixture of gases. Several of these waste tanks (currently twenty-five, 6 Double Shell Tanks and 19 Single Shell Tanks) were identified as having the potential for the buildup of gasses to a flammable level. An active ventilation system in the Double Shell Tanks and a passive ventilation system in the Single Shell Tanks provides a method of expelling gasses from the tanks. A gas release from a tank causes a temporary rise in the tank pressure, and a potential for increased concentration of hydrogen gas in the vapor space. The gas is released via the ventilation systems until a uniform gas mixture in the vapor space is once again achieved. The Standard Hydrogen Monitoring System (SHMS) is designed to monitor and quantify the percent hydrogen concentration during these potential gas releases. This document describes the design of the Standard-D Hydrogen Monitoring System, (SHMS-D) and its components as it differs from the original SHMS.

Adsorption of hydrogen on copper catalysts  

SciTech Connect (OSTI)

Copper catalysts display a high activity and selectivity in the hydrogenation of various carbonyl compounds, and copper is a component of the complex catalysts for the synthesis of methanol from CO and H/sub 2/. The adsorption of H/sub 2/ on copper catalysts has been studied by means of thermal desorption. The molecular form of adsorption of H/sub 2/ has been established, the thermal desorption parameters calculated, and the heat of adsorption of H/sub 2/ on a copper surface estimated.

Magnetic liquefier for hydrogen  

SciTech Connect (OSTI)

This document summarizes work done at the Astronautics Technology Center of the Astronautics Corporation of America (ACA) in Phase 1 of a four phase program leading to the development of a magnetic liquefier for hydrogen. The project involves the design, fabrication, installation, and operation of a hydrogen liquefier providing significantly reduced capital and operating costs, compared to present liquefiers. To achieve this goal, magnetic refrigeration, a recently developed, highly efficient refrigeration technology, will be used for the liquefaction process. Phase 1 project tasks included liquefier conceptual design and analysis, preliminary design of promising configurations, design selection, and detailed design of the selected design. Fabrication drawings and vendor specifications for the selected design were completed during detailed design. The design of a subscale, demonstration magnetic hydrogen liquefier represents a significant advance in liquefaction technology. The cost reductions that can be realized in hydrogen liquefaction in both the subscale and, more importantly, in the full-scale device are expected to have considerable impact on the use of liquid hydrogen in transportation, chemical, and electronic industries. The benefits to the nation from this technological advance will continue to have importance well into the 21st century.

Hydrogen-Selective Membrane  

DOE Patents [OSTI]

A hydrogen-selective membrane comprises a tubular porous ceramic support having a palladium metal layer deposited on an inside surface of the ceramic support. The thickness of the palladium layer is greater than about 10 .mu.m but typically less than about 20 .mu.m. The hydrogen permeation rate of the membrane is greater than about 1.0 moles/m.sup.2.s at a temperature of greater than about 500.degree. C. and a transmembrane pressure difference of about 1,500 kPa. Moreover, the hydrogen-to-nitrogen selectivity is greater than about 600 at a temperature of greater than about 500.degree. C. and a transmembrane pressure of about 700 kPa. Hydrogen can be separated from a mixture of gases using the membrane. The method may include the step of heating the mixture of gases to a temperature of greater than about 400.degree. C. and less than about 1000.degree. C. before the step of flowing the mixture of gases past the membrane. The mixture of gases may include ammonia. The ammonia typically is decomposed to provide nitrogen and hydrogen using a catalyst such as nickel. The catalyst may be placed inside the tubular ceramic support. The mixture of gases may be supplied by an industrial process such as the mixture of exhaust gases from the IGCC process.

Water's Hydrogen Bond Strength  

E-Print Network [OSTI]

Water is necessary both for the evolution of life and its continuance. It possesses particular properties that cannot be found in other materials and that are required for life-giving processes. These properties are brought about by the hydrogen bonded environment particularly evident in liquid water. Each liquid water molecule is involved in about four hydrogen bonds with strengths considerably less than covalent bonds but considerably greater than the natural thermal energy. These hydrogen bonds are roughly tetrahedrally arranged such that when strongly formed the local clustering expands, decreasing the density. Such low density structuring naturally occurs at low and supercooled temperatures and gives rise to many physical and chemical properties that evidence the particular uniqueness of liquid water. If aqueous hydrogen bonds were actually somewhat stronger then water would behave similar to a glass, whereas if they were weaker then water would be a gas and only exist as a liquid at sub-zero temperatures. The overall conclusion of this investigation is that water's hydrogen bond strength is poised centrally within a narrow window of its suitability for life.

ENERGY | Hydrogen Economy  

Science Journals Connector (OSTI)

Abstract The growing concerns about global climate change, local pollution, and availability and security of energy supply have drawn the larger public attention, well outside the frontiers of the research community. A large debate has been considering the potential benefits of a hydrogen economy with low- or carbon-free primary energy sources. The attractive potential of hydrogen is countered by uncertainties about the development and the economics of the implied key enabling technologies, such as renewable energy sources, advanced production processes, fuel cells (FCs), novel storage technologies, safety, and a brand new or a substantially modified infrastructure. A paradigm shift to a hydrogen economy will surely require substantial research and development (R&D) breakthroughs on critical technologies with a lengthy transitional approach.

Hydrogen production from microbial strains  

DOE Patents [OSTI]

The present invention is directed to a method of screening microbe strains capable of generating hydrogen. This method involves inoculating one or more microbes in a sample containing cell culture medium to form an inoculated culture medium. The inoculated culture medium is then incubated under hydrogen producing conditions. Once incubating causes the inoculated culture medium to produce hydrogen, microbes in the culture medium are identified as candidate microbe strains capable of generating hydrogen. Methods of producing hydrogen using one or more of the microbial strains identified as well as the hydrogen producing strains themselves are also disclosed.

, 2006 , 2006 DOE-Funded Technology to Upgrade Low-Quality Natural Gas Commercialized Research Targets Subquality Gas Resource Comprising a Third of U.S. Gas Reserves TULSA, OK- A new Department of Energy-funded technology to upgrade low-quality natural gas-a resource that accounts for almost one-third of America's known gas reserves-has been successfully commercialized and is now a multimillion-dollar business. A large portion of the nation's natural gas production stream comes out of the ground contaminated by water, carbon dioxide, hydrogen sulfide, or nitrogen and other inert gases. These contaminants must be removed from the production stream in order to provide pipeline-quality natural gas for delivery to consumers. This low-quality natural gas resource has been estimated at more than 60 trillion cubic feet (Tcf) of the Nation's total proved gas reserves of more than 192 Tcf.

Dynamic Model of Hydrogen in GaN  

Broader source: All U.S. Department of Energy (DOE) Office Webpages (Extended Search)

Dynamic Model of Hydrogen in GaN by S. M. Myers and A. F. Wright Motivation-Hydrogen is incorporated into p-type GaN during MOCVD growth, producing highly stable passivation of the Mg acceptors. Complete acceptor activation by thermal H release requires temperatures that threaten material integrity, prompting compromises in device processing. At lower temperatures, forward bias of p-n junctions or electron-beam irradiation produces a metastable, reversible activation without H release. To understand and control such effects, we are developing a mathematical model of H behavior wherein state energies from density-functional theory are employed in diffusion-reaction equations. Previously, we used the greatly simplifying assumptions of local equilibrium among states

Catalytic hydrogenation of HyperCoal (ashless coal) and reusability of catalyst  

SciTech Connect (OSTI)

HyperCoal (HPC) is ashless coal obtained by a mild thermal extraction of coal to remove unextractable, heavy compounds, and minerals. The temperature and duration of HPC hydrogenation was systematically varied with and without solvent in an autoclave under hydrogen pressure. Unlike raw coal, hydrogenation of HPC in the absence of solvent proceeded without coke formation when the reaction was performed for 60 min at 450{sup o}C in 10 MPa hydrogen (initial pressure). The hydrogenation catalyst was recycled five times with no detection of deactivation. Longer reactions at slightly higher temperatures (120 min at 460{sup o}C), with replenishing the hydrogen, afforded a 90 wt % oil (hexane-soluble fraction) yield. 27 refs., 8 figs., 2 tabs.

Hydrogen production by the decomposition of water  

DOE Patents [OSTI]

How to produce hydrogen from water was a problem addressed by this invention. The solution employs a combined electrolytical-thermochemical sulfuric acid process. Additionally, high purity sulfuric acid can be produced in the process. Water and SO.sub.2 react in electrolyzer (12) so that hydrogen is produced at the cathode and sulfuric acid is produced at the anode. Then the sulfuric acid is reacted with a particular compound M.sub.r X.sub.s so as to form at least one water insoluble sulfate and at least one water insoluble oxide of molybdenum, tungsten, or boron. Water is removed by filtration; and the sulfate is decomposed in the presence of the oxide in sulfate decomposition zone (21), thus forming SO.sub.3 and reforming M.sub.r X.sub.s. The M.sub.r X.sub.s is recycled to sulfate formation zone (16). If desired, the SO.sub.3 can be decomposed to SO.sub.2 and O.sub.2 ; and the SO.sub.2 can be recycled to electrolyzer (12) to provide a cycle for producing hydrogen.

Deep Sludge Gas Release Event Analytical Evaluation  

SciTech Connect (OSTI)

Long Abstract. Full Text. The purpose of the Deep Sludge Gas Release Event Analytical Evaluation (DSGRE-AE) is to evaluate the postulated hypothesis that a hydrogen GRE may occur in Hanford tanks containing waste sludges at levels greater than previously experienced. There is a need to understand gas retention and release hazards in sludge beds which are 200 -300 inches deep. These sludge beds are deeper than historical Hanford sludge waste beds, and are created when waste is retrieved from older single-shell tanks (SST) and transferred to newer double-shell tanks (DST).Retrieval of waste from SSTs reduces the risk to the environment from leakage or potential leakage of waste into the ground from these tanks. However, the possibility of an energetic event (flammable gas accident) in the retrieval receiver DST is worse than slow leakage. Lines of inquiry, therefore, are (1) can sludge waste be stored safely in deep beds; (2) can gas release events (GRE) be prevented by periodically degassing the sludge (e.g., mixer pump); or (3) does the retrieval strategy need to be altered to limit sludge bed height by retrieving into additional DSTs? The scope of this effort is to provide expert advice on whether or not to move forward with the generation of deep beds of sludge through retrieval of C-Farm tanks. Evaluation of possible mitigation methods (e.g., using mixer pumps to release gas, retrieving into an additional DST) are being evaluated by a second team and are not discussed in this report. While available data and engineering judgment indicate that increased gas retention (retained gas fraction) in DST sludge at depths resulting from the completion of SST 241-C Tank Farm retrievals is not expected and, even if gas releases were to occur, they would be small and local, a positive USQ was declared (Occurrence Report EM-RP--WRPS-TANKFARM-2012-0014, "Potential Exists for a Large Spontaneous Gas Release Event in Deep Settled Waste Sludge"). The purpose of this technical report is to (1) present and discuss current understandings of gas retention and release mechanisms for deep sludge in U.S. Department of Energy (DOE) complex waste storage tanks; and (2) to identify viable methods/criteria for demonstrating safety relative to deep sludge gas release events (DSGRE) in the near term to support the Hanford C-Farm retrieval mission. A secondary purpose is to identify viable methods/criteria for demonstrating safety relative to DSGREs in the longer term to support the mission to retrieve waste from the Hanford Tank Farms and deliver it to the Waste Treatment and Immobilization Plant (WTP). The potential DSGRE issue resulted in the declaration of a positive Unreviewed Safety Question (USQ). C-Farm retrievals are currently proceeding under a Justification for Continued Operation (JCO) that only allows tanks 241-AN-101 and 241-AN-106 sludge levels of 192 inches and 195 inches, respectively. C-Farm retrievals need deeper sludge levels (approximately 310 inches in 241-AN-101 and approximately 250 inches in 241-AN-106). This effort is to provide analytical data and justification to continue retrievals in a safe and efficient manner.
