But new developments of the polymer electrolyte membrane (PEM) fuel cells make it possible to realize the electrochemical compression in a PEM-cell with high eciency.

Zecchina, S. Bordiga, J. G. Vitillo, G. Ricchiardi, C. Lamberti, G. Spoto, M. Bjørgen and K. P. Lillerud, J. Am. Chem. Soc., 2005, 127, 6361]. The aim of this new study is thus to clarify both the role played by the acidic strength and by the density of the polarizing centers hosted in the same framework topology in the increase of the adsorptive capabilities of the chabazitic materials towards H 2 . To achieve this goal, the volumetric experiments of H 2 uptake (performed at 77 K) and the transmission IR experiment of H 2 adsorption at 15 K have been performed on H-SSZ-13, H-SAPO-34 (the isostructural silico-aluminophosphate material with the same Brønsted site density) and H-CHA (the standard chabazite zeolite: Si/Al ¼ 2.1) materials. We have found that a H 2 uptake improvement has been obtained by increasing the acidic strength of the Brønsted sites (moving from H-SAPO-34 to H-SSZ-13). Conversely, the important increase of the Brønsted sites density (moving from H-SSZ-13 to H-CHA) has played a negative role. This unexpected behavior has been explained as follows. The additional Brønsted sites are in mutual interaction via H-bonds inside the small cages of the chabazitic framework and for most of them the energetic cost needed to displace the adjacent OH ligand is higher than the adsorption enthalpy of the OHÁ Á ÁH 2 adduct. From our work it can be concluded that proton exchanged chabazitic frameworks represent, among zeolites, the most efficient materials for hydrogen storage. We have shown that a proper balance between available space (volume accessible to hydrogen), high contact surface, and specific interaction with strong and isolated polarizing centers are the necessary characteristics requested to design better materials for molecular H 2 storage.

Zecchina, S. Bordiga, J. G. Vitillo, G. Ricchiardi, C. Lamberti, G. Spoto, M. Bjørgen and K. P. Lillerud, J. Am. Chem. Soc., 2005, 127, 6361]. The aim of this new study is thus to clarify both the role played by the acidic strength and by the density of the polarizing centers hosted in the same framework topology in the increase of the adsorptive capabilities of the chabazitic materials towards H 2 . To achieve this goal, the volumetric experiments of H 2 uptake (performed at 77 K) and the transmission IR experiment of H 2 adsorption at 15 K have been performed on H-SSZ-13, H-SAPO-34 (the isostructural silico-aluminophosphate material with the same Brønsted site density) and H-CHA (the standard chabazite zeolite: Si/Al ¼ 2.1) materials. We have found that a H 2 uptake improvement has been obtained by increasing the acidic strength of the Brønsted sites (moving from H-SAPO-34 to H-SSZ-13). Conversely, the important increase of the Brønsted sites density (moving from H-SSZ-13 to H-CHA) has played a negative role. This unexpected behavior has been explained as follows. The additional Brønsted sites are in mutual interaction via H-bonds inside the small cages of the chabazitic framework and for most of them the energetic cost needed to displace the adjacent OH ligand is higher than the adsorption enthalpy of the OHÁ Á ÁH 2 adduct. From our work it can be concluded that proton exchanged chabazitic frameworks represent, among zeolites, the most efficient materials for hydrogen storage. We have shown that a proper balance between available space (volume accessible to hydrogen), high contact surface, and specific interaction with strong and isolated polarizing centers are the necessary characteristics requested to design better materials for molecular H 2 storage.

The work carried out on representative AB(sub 5) and AB(sub 2) type modified alloys (by partial substitution or with small additives of other elements) is presented. The purpose of the modification was to optimize the thermodynamics and kinetics of the hydriding/dehydriding reactions and enhance the stabilities of the alloys for the desired battery applications. The results of our collaboration, to date, demonstrate that (1) alloys prepared by arc melting/annealing and mechanical alloying/annealing techniques exhibit similar morphology, composition and hydriding/dehydriding characteristics; (2) alloys with the appropriate small amounts of substituent or additive elements: (1) retain the single phase structure, (2) improve the hydriding/dehydriding reactions for the battery applications, and (3) enhance the stability in the battery environment; and (3) the AB(sub 2) type alloys exhibit higher energy densities than the AB(sub 5) type alloys but the state-of-the-art, commercialized batteries are predominantly manufactured using Ab(sub 5) type alloys.</div></div></div><ul class="InlineList u-ph0x u-fs13"><li class="InlineList-item logged_in_only"><div class="share_on_academia_work_button"><a class="academia_share Button Button--inverseBlue Button--sm js-bookmark-button" data-academia-share="Work/7191691" data-share-source="work_strip" data-spinner="small_white_hide_contents"><i class="fa fa-plus"></i><span class="work-strip-link-text u-ml1x" data-content="button_text">Bookmark</span></a></div></li><li class="InlineList-item"><div class="download"><a id="0b6c166258602774804845dfa9729fce" rel="nofollow" data-download="{"attachment_id":48568212,"asset_id":7191691,"asset_type":"Work","always_allow_download":false,"track":null,"button_location":"work_strip","source":null,"hide_modal":null}" class="Button Button--sm Button--inverseGreen js-download-button prompt_button doc_download" href="https://www.academia.edu/attachments/48568212/download_file?st=MTczNzQzNDAwMyw4LjIyMi4yMDguMTQ2&s=work_strip"><i class="fa fa-arrow-circle-o-down fa-lg"></i><span class="u-textUppercase u-ml1x" data-content="button_text">Download</span></a></div></li><li class="InlineList-item"><ul class="InlineList InlineList--bordered u-ph0x"><li class="InlineList-item InlineList-item--bordered"><span class="InlineList-item-text">by <span itemscope="itemscope" itemprop="author" itemtype="https://schema.org/Person"><a class="u-tcGrayDark u-fw700" data-has-card-for-user="12462799" href="https://independent.academia.edu/PaulAnanie">Paul Ananie</a><script data-card-contents-for-user="12462799" type="text/json">{"id":12462799,"first_name":"Paul","last_name":"Ananie","domain_name":"independent","page_name":"PaulAnanie","display_name":"Paul Ananie","profile_url":"https://independent.academia.edu/PaulAnanie?f_ri=21551","photo":"/images/s65_no_pic.png"}</script></span></span></li><li class="js-paper-rank-work_7191691 InlineList-item InlineList-item--bordered hidden"><span class="js-paper-rank-view hidden u-tcGrayDark" data-paper-rank-work-id="7191691"><i class="u-m1x fa fa-bar-chart"></i><strong class="js-paper-rank"></strong></span><script>$(function() { new Works.PaperRankView({ workId: 7191691, container: ".js-paper-rank-work_7191691", });

(2) examine their physico-chemical characteristics (morphology, composition); (3) determine the hydrogen absorption/desorption behavior (pressure-composition isotherms as a function of temperature); and (4) evaluate their performance characteristics as hydride electrodes (charge/discharge, capacity retention, cycle life, high rate capability). The work carried out on representative AB(sub 5) and AB(sub 2) type modified alloys (by partial substitution or with small additives of other elements) is presented. The purpose of the modification was to optimize the thermodynamics and kinetics of the hydriding/dehydriding reactions and enhance the stabilities of the alloys for the desired battery applications. The results of our collaboration, to date, demonstrate that (1) alloys prepared by arc melting/annealing and mechanical alloying/annealing techniques exhibit similar morphology, composition and hydriding/dehydriding characteristics; (2) alloys with the appropriate small amounts of substituent or additive elements: (1) retain the single phase structure, (2) improve the hydriding/dehydriding reactions for the battery applications, and (3) enhance the stability in the battery environment; and (3) the AB(sub 2) type alloys exhibit higher energy densities than the AB(sub 5) type alloys but the state-of-the-art, commercialized batteries are predominantly manufactured using Ab(sub 5) type alloys.","downloadable_attachments":[{"id":48568212,"asset_id":7191691,"asset_type":"Work","always_allow_download":false}],"ordered_authors":[{"id":12462799,"first_name":"Paul","last_name":"Ananie","domain_name":"independent","page_name":"PaulAnanie","display_name":"Paul Ananie","profile_url":"https://independent.academia.edu/PaulAnanie?f_ri=21551","photo":"/images/s65_no_pic.png"}],"research_interests":[{"id":48,"name":"Engineering","url":"https://www.academia.edu/Documents/in/Engineering?f_ri=21551","nofollow":true},{"id":522,"name":"Thermodynamics","url":"https://www.academia.edu/Documents/in/Thermodynamics?f_ri=21551","nofollow":true},{"id":4987,"name":"Kinetics","url":"https://www.academia.edu/Documents/in/Kinetics?f_ri=21551","nofollow":true},{"id":21551,"name":"Hydrogen Storage","url":"https://www.academia.edu/Documents/in/Hydrogen_Storage?f_ri=21551","nofollow":true},{"id":53166,"name":"Power","url":"https://www.academia.edu/Documents/in/Power?f_ri=21551"},{"id":194828,"name":"Nickel","url":"https://www.academia.edu/Documents/in/Nickel?f_ri=21551"},{"id":260118,"name":"CHEMICAL SCIENCES","url":"https://www.academia.edu/Documents/in/CHEMICAL_SCIENCES?f_ri=21551"},{"id":1852738,"name":"Power Sources","url":"https://www.academia.edu/Documents/in/Power_Sources?f_ri=21551"}]}, }) } })();</script></ul></li></ul></div></div><div class="u-borderBottom1 u-borderColorGrayLighter"><div class="clearfix u-pv7x u-mb0x js-work-card work_59525684" data-work_id="59525684" itemscope="itemscope" itemtype="https://schema.org/ScholarlyArticle"><div class="header"><div class="title u-fontSerif u-fs22 u-lineHeight1_3"><a class="u-tcGrayDarkest js-work-link" href="https://www.academia.edu/59525684/The_Emergence_of_a_Dominant_Design_a_study_on_hydrogen_prototypes">The Emergence of a Dominant Design – a study on hydrogen prototypes</a></div></div><div class="u-pb4x u-mt3x"><div class="summary u-fs14 u-fw300 u-lineHeight1_5 u-tcGrayDarkest"><div class="summarized">The notion of dominant designs deals with dominance in the market and the dominant design is thought to be dominant because of market selection forces.

It is described how hydrogen storage can be applied in both isolated and grid-connected systems, and how the produced hydrogen can be utilized for stationary energy supply and as a fuel for transportation. The paper discusses the benefits and limitations of the different hydrogen storage applications, and emphasizes the need for stochastic studies both for long-term planning and operation planning. A simulation case study of using excess wind power in a weak grid to produce hydrogen for vehicles has been presented. It is shown that the penetration of wind power can be significantly increased by introducing electrolytic hydrogen production as a controllable load</div></div></div><ul class="InlineList u-ph0x u-fs13"><li class="InlineList-item logged_in_only"><div class="share_on_academia_work_button"><a class="academia_share Button Button--inverseBlue Button--sm js-bookmark-button" data-academia-share="Work/17405896" data-share-source="work_strip" data-spinner="small_white_hide_contents"><i class="fa fa-plus"></i><span class="work-strip-link-text u-ml1x" data-content="button_text">Bookmark</span></a></div></li><li class="InlineList-item"><div class="download"><a id="66464dea1714d01559e35279caad3b99" rel="nofollow" data-download="{"attachment_id":42262335,"asset_id":17405896,"asset_type":"Work","always_allow_download":false,"track":null,"button_location":"work_strip","source":null,"hide_modal":null}" class="Button Button--sm Button--inverseGreen js-download-button prompt_button doc_download" href="https://www.academia.edu/attachments/42262335/download_file?st=MTczNzQzNDAwMyw4LjIyMi4yMDguMTQ2&s=work_strip"><i class="fa fa-arrow-circle-o-down fa-lg"></i><span class="u-textUppercase u-ml1x" data-content="button_text">Download</span></a></div></li><li class="InlineList-item"><ul class="InlineList InlineList--bordered u-ph0x"><li class="InlineList-item InlineList-item--bordered"><span class="InlineList-item-text">by <span itemscope="itemscope" itemprop="author" itemtype="https://schema.org/Person"><a class="u-tcGrayDark u-fw700" data-has-card-for-user="37128415" href="https://independent.academia.edu/MagnusKorp%C3%A5s">Magnus Korpås</a><script data-card-contents-for-user="37128415" type="text/json">{"id":37128415,"first_name":"Magnus","last_name":"Korpås","domain_name":"independent","page_name":"MagnusKorpås","display_name":"Magnus Korpås","profile_url":"https://independent.academia.edu/MagnusKorp%C3%A5s?f_ri=21551","photo":"/images/s65_no_pic.png"}</script></span></span></li><li class="js-paper-rank-work_17405896 InlineList-item InlineList-item--bordered hidden"><span class="js-paper-rank-view hidden u-tcGrayDark" data-paper-rank-work-id="17405896"><i class="u-m1x fa fa-bar-chart"></i><strong class="js-paper-rank"></strong></span><script>$(function() { new Works.PaperRankView({ workId: 17405896, container: ".js-paper-rank-work_17405896", });

It is described how hydrogen storage can be applied in both isolated and grid-connected systems, and how the produced hydrogen can be utilized for stationary energy supply and as a fuel for transportation. The paper discusses the benefits and limitations of the different hydrogen storage applications, and emphasizes the need for stochastic studies both for long-term planning and operation planning. A simulation case study of using excess wind power in a weak grid to produce hydrogen for vehicles has been presented. It is shown that the penetration of wind power can be significantly increased by introducing electrolytic hydrogen production as a controllable

Degradation rates are typically around 15% for 20 years, or around 0.8% per anum. That means a 1 kW system will produce 84% of its original power output after two decades. Panel type: 275-280/330-335W Multi-Module Price per watt (USD): 0.28 High, 0.175 Low, 0.185 Average. The average price for 350-watt panels is 18.5 cents per watt. The second major cost input is the DC/AC converter. Using data from Alibaba, numerous products were sampled. The most cost-competitive DC/AC rectifiers were ones used for solar-powered well water pumps. 7.5 kW units were priced around $250, yielding a price per kilowatt of $34. In our case, we only need a DC-DC converter, stepping down the voltage from the panel peak of around 35 to 12 for the electrolyzer. DC/DC converters are roughly the same price as DC/AC inverters. The Levelized Cost of Energy (LCOE) is determined by the irradiance available much more so than it is by slight differences in the panel module costs. A solar array in Scotland (880 kWh/kWp/yr) won't be nearly as cheap as one in Chile (2300 kWh/kWp/yr), or in Los Vegas (1900 kWh/kWp/yr). With the availability of low-cost photovoltaic energy without the need for balancing grid requirements, the need for storage is eliminated, this opens up the possibility of producing ultra-low cost hydrogen below the price of methane reforming.

Degradation rates are typically around 15% for 20 years, or around 0.8% per anum. That means a 1 kW system will produce 84% of its original power output after two decades. Panel type: 275-280/330-335W Multi-Module Price per watt (USD): 0.28 High, 0.175 Low, 0.185 Average. The average price for 350-watt panels is 18.5 cents per watt. The second major cost input is the DC/AC converter. Using data from Alibaba, numerous products were sampled. The most cost-competitive DC/AC rectifiers were ones used for solar-powered well water pumps. 7.5 kW units were priced around $250, yielding a price per kilowatt of $34. In our case, we only need a DC-DC converter, stepping down the voltage from the panel peak of around 35 to 12 for the electrolyzer. DC/DC converters are roughly the same price as DC/AC inverters. The Levelized Cost of Energy (LCOE) is determined by the irradiance available much more so than it is by slight differences in the panel module costs. A solar array in Scotland (880 kWh/kWp/yr) won't be nearly as cheap as one in Chile (2300 kWh/kWp/yr), or in Los Vegas (1900 kWh/kWp/yr). With the availability of low-cost photovoltaic energy without the need for balancing grid requirements, the need for storage is eliminated, this opens up the possibility of producing ultra-low cost hydrogen below the price of methane reforming.

bialkali Na−Li−Al−H hydrogen storage system. The integrated approach has broad utility for the discovery, understanding, and optimization of solid-state chemical systems. Density functional theory ground-state minimizations, low-temperature powder neutron diffraction, and low-temperature synchrotron X-ray diffraction were coupled to refine the crystallographic structures for various low-temperature distorted Na 2 LiAlH 6 allotropes. Direct method lattice dynamics were used to identify a stable Na 2 -LiAlH 6 allotrope for thermodynamic property predictions. The results were interpreted to propose transformation pathways between this allotrope and the less stable cubic allotrope observed at room temperature. The calculated bialkali dissociation pressure relationships were compared with those determined from pressure-composition-isotherm experiments to validate the predicted thermodynamic properties. These predictions enabled computational thermodynamic modeling of Na 2 LiAlH 6 and competing lower order phases within the Na−Li−Al−H system over a wide of temperature and pressure conditions. The predictions were substantiated by experimental observations of varying Na 2 LiAlH 6 dehydrogenation behavior with temperature.

The integrated approach has broad utility for the discovery, understanding, and optimization of solid-state chemical systems. Density functional theory ground-state minimizations, low-temperature powder neutron diffraction, and low-temperature synchrotron X-ray diffraction were coupled to refine the crystallographic structures for various low-temperature distorted Na 2 LiAlH 6 allotropes. Direct method lattice dynamics were used to identify a stable Na 2 -LiAlH 6 allotrope for thermodynamic property predictions. The results were interpreted to propose transformation pathways between this allotrope and the less stable cubic allotrope observed at room temperature. The calculated bialkali dissociation pressure relationships were compared with those determined from pressure-composition-isotherm experiments to validate the predicted thermodynamic properties. These predictions enabled computational thermodynamic modeling of Na 2 LiAlH 6 and competing lower order phases within the Na−Li−Al−H system over a wide of temperature and pressure conditions. The predictions were substantiated by experimental observations of varying Na 2 LiAlH 6 dehydrogenation behavior with temperature. The modeling was used to identify the most favorable reaction pathways and equilibrium products for H discharge/recharge in the Na−Li−Al−H system, and to design conditions that maximize the theoretical hydrogen reversibility within the Na−Li−Al−H system.","downloadable_attachments":[{"id":43675502,"asset_id":14983974,"asset_type":"Work","always_allow_download":false}],"ordered_authors":[{"id":33980368,"first_name":"Ole","last_name":"Løvvik","domain_name":"independent","page_name":"OleLøvvik","display_name":"Ole Løvvik","profile_url":"https://independent.academia.edu/OleL%C3%B8vvik?f_ri=21551","photo":"/images/s65_no_pic.png"},{"id":34840784,"first_name":"Bjørn","last_name":"Hauback","domain_name":"independent","page_name":"BjørnHauback","display_name":"Bjørn Hauback","profile_url":"https://independent.academia.edu/Bj%C3%B8rnHauback?f_ri=21551","photo":"/images/s65_no_pic.png"}],"research_interests":[{"id":72,"name":"Chemical Engineering","url":"https://www.academia.edu/Documents/in/Chemical_Engineering?f_ri=21551","nofollow":true},{"id":522,"name":"Thermodynamics","url":"https://www.academia.edu/Documents/in/Thermodynamics?f_ri=21551","nofollow":true},{"id":530,"name":"Inorganic Chemistry","url":"https://www.academia.edu/Documents/in/Inorganic_Chemistry?f_ri=21551","nofollow":true},{"id":21551,"name":"Hydrogen Storage","url":"https://www.academia.edu/Documents/in/Hydrogen_Storage?f_ri=21551","nofollow":true},{"id":21553,"name":"Neutron Diffraction","url":"https://www.academia.edu/Documents/in/Neutron_Diffraction?f_ri=21551"},{"id":285086,"name":"Integrated Approach","url":"https://www.academia.edu/Documents/in/Integrated_Approach?f_ri=21551"},{"id":339306,"name":"Lattice Dynamics","url":"https://www.academia.edu/Documents/in/Lattice_Dynamics?f_ri=21551"},{"id":391252,"name":"Room Temperature","url":"https://www.academia.edu/Documents/in/Room_Temperature?f_ri=21551"},{"id":616972,"name":"Low Temperature","url":"https://www.academia.edu/Documents/in/Low_Temperature?f_ri=21551"},{"id":1256879,"name":"Thermodynamic Properties","url":"https://www.academia.edu/Documents/in/Thermodynamic_Properties?f_ri=21551"},{"id":1763339,"name":"Direct Method","url":"https://www.academia.edu/Documents/in/Direct_Method?f_ri=21551"}]}, }) } })();</script></ul></li></ul></div></div><div class="u-borderBottom1 u-borderColorGrayLighter"><div class="clearfix u-pv7x u-mb0x js-work-card work_23068217" data-work_id="23068217" itemscope="itemscope" itemtype="https://schema.org/ScholarlyArticle"><div class="header"><div class="title u-fontSerif u-fs22 u-lineHeight1_3"><a class="u-tcGrayDarkest js-work-link" href="https://www.academia.edu/23068217/Electroless_deposition_of_Ni_nanoparticles_on_carbon_nanotubes_with_the_aid_of_supercritical_CO2_fluid_and_a_synergistic_hydrogen_storage_property_of_the_composite">Electroless deposition of Ni nanoparticles on carbon nanotubes with the aid of supercritical CO2 fluid and a synergistic hydrogen storage property of the composite</a></div></div><div class="u-pb4x u-mt3x"><div class="summary u-fs14 u-fw300 u-lineHeight1_5 u-tcGrayDarkest"><div class="summarized">Battery graphite rod was modified with Ni nanoparticles with a new electroless procedure and the performance of the proposed electrode was evaluated as a non-enzymatic anode for electrocatalytic oxidation of glucose in alkaline media.... <a class="more_link u-tcGrayDark u-linkUnstyled" data-container=".work_23068217" data-show=".complete" data-hide=".summarized" data-more-link-behavior="true" href="#">more</a></div><div class="complete hidden">Battery graphite rod was modified with Ni nanoparticles with a new electroless procedure and the performance of the proposed electrode was evaluated as a non-enzymatic anode for electrocatalytic oxidation of glucose in alkaline media.

embrittlement of stainless steels in case of high pressure hydrogen storage systems by the formation of a single γ C layer. Electrical conductivity and corrosion resistance were enhanced by plasma nitriding. Tests with single cells have shown a 15% higher voltage compared to graphite plates at low temperatures and reduced treatment durations. The substitution of high alloyed stable stainless steel grades by cheaper metastable stainless grades depends on a successful suppression of hydrogen environmental embrittlement. A promising way could be a surface treatment resulting in the formation of a γ C layer on top of the surface. Plasma nitrocarburizing can form such γ C layer, but a variation of treatment temperature and CH 4 content was not successful in suppressing the undesired S-phase as a top layer.</div></div></div><ul class="InlineList u-ph0x u-fs13"><li class="InlineList-item logged_in_only"><div class="share_on_academia_work_button"><a class="academia_share Button Button--inverseBlue Button--sm js-bookmark-button" data-academia-share="Work/29606815" data-share-source="work_strip" data-spinner="small_white_hide_contents"><i class="fa fa-plus"></i><span class="work-strip-link-text u-ml1x" data-content="button_text">Bookmark</span></a></div></li><li class="InlineList-item"><div class="download"><a id="65c45c40d73ea1df32c484145d468bee" rel="nofollow" data-download="{"attachment_id":50048807,"asset_id":29606815,"asset_type":"Work","always_allow_download":false,"track":null,"button_location":"work_strip","source":null,"hide_modal":null}" class="Button Button--sm Button--inverseGreen js-download-button prompt_button doc_download" href="https://www.academia.edu/attachments/50048807/download_file?st=MTczNzQzNDAwMyw4LjIyMi4yMDguMTQ2&s=work_strip"><i class="fa fa-arrow-circle-o-down fa-lg"></i><span class="u-textUppercase u-ml1x" data-content="button_text">Download</span></a></div></li><li class="InlineList-item"><ul class="InlineList InlineList--bordered u-ph0x"><li class="InlineList-item InlineList-item--bordered"><span class="InlineList-item-text">by <span itemscope="itemscope" itemprop="author" itemtype="https://schema.org/Person"><a class="u-tcGrayDark u-fw700" data-has-card-for-user="56110255" href="https://independent.academia.edu/PeterKaestner">Peter Kaestner</a><script data-card-contents-for-user="56110255" type="text/json">{"id":56110255,"first_name":"Peter","last_name":"Kaestner","domain_name":"independent","page_name":"PeterKaestner","display_name":"Peter Kaestner","profile_url":"https://independent.academia.edu/PeterKaestner?f_ri=21551","photo":"/images/s65_no_pic.png"}</script></span></span><span class="u-displayInlineBlock InlineList-item-text"> and <span class="u-textDecorationUnderline u-clickable InlineList-item-text js-work-more-authors-29606815">+1</span><div class="hidden js-additional-users-29606815"><div><span itemscope="itemscope" itemprop="author" itemtype="https://schema.org/Person"><a href="https://independent.academia.edu/ThorstenMichler">Thorsten Michler</a></span></div></div></span><script>(function(){ var popoverSettings = { el: $('.js-work-more-authors-29606815'), placement: 'bottom', hide_delay: 200, html: true, content: function(){ return $('.js-additional-users-29606815').html();

Palladium-doped carbon fibers exhibited emhanced hydrogen uptake compared to the corresponding palladium-free nanoporous carbon fibers (at room temperature and 2 MPa pressure). However, the mechanism responsible for the enhanced hydrogen uptake is not fully understood.

Palladium-doped carbon fibers exhibited emhanced hydrogen uptake compared to the corresponding palladium-free nanoporous carbon fibers (at room temperature and 2 MPa pressure). However, the mechanism responsible for the enhanced hydrogen uptake is not fully understood. New findings are presented in this paper in support of a mechanism that encompasses both hydrogen spillover on palladium metal sites and hydrogen physisorption on nanostructured carbon sites.","downloadable_attachments":[{"id":43377526,"asset_id":15273429,"asset_type":"Work","always_allow_download":false}],"ordered_authors":[{"id":34352042,"first_name":"Cristian","last_name":"Contescu","domain_name":"independent","page_name":"CristianContescu","display_name":"Cristian Contescu","profile_url":"https://independent.academia.edu/CristianContescu?f_ri=21551","photo":"/images/s65_no_pic.png"},{"id":43167442,"first_name":"Dan","last_name":"Edie","domain_name":"independent","page_name":"DanEdie","display_name":"Dan Edie","profile_url":"https://independent.academia.edu/DanEdie?f_ri=21551","photo":"/images/s65_no_pic.png"}],"research_interests":[{"id":21551,"name":"Hydrogen Storage","url":"https://www.academia.edu/Documents/in/Hydrogen_Storage?f_ri=21551","nofollow":true},{"id":39753,"name":"Activated Carbon","url":"https://www.academia.edu/Documents/in/Activated_Carbon?f_ri=21551","nofollow":true},{"id":391252,"name":"Room Temperature","url":"https://www.academia.edu/Documents/in/Room_Temperature?f_ri=21551","nofollow":true},{"id":869231,"name":"Carbon Fiber","url":"https://www.academia.edu/Documents/in/Carbon_Fiber?f_ri=21551","nofollow":true}]}, }) } })();</script></ul></li></ul></div></div><div class="u-borderBottom1 u-borderColorGrayLighter"><div class="clearfix u-pv7x u-mb0x js-work-card work_1081863" data-work_id="1081863" itemscope="itemscope" itemtype="https://schema.org/ScholarlyArticle"><div class="header"><div class="title u-fontSerif u-fs22 u-lineHeight1_3"><a class="u-tcGrayDarkest js-work-link" href="https://www.academia.edu/1081863/Reaction_of_hydrogen_with_the_Laves_phase_C14_TiCr1_78_xMnx_compounds">Reaction of hydrogen with the Laves phase (C14) TiCr1. 78-xMnx compounds</a></div></div><div class="u-pb4x u-mt3x"><div class="summary u-fs14 u-fw300 u-lineHeight1_5 u-tcGrayDarkest"><div class="summarized">The lattice constants a and c of the as cast hexagonal (C14) Laves phase TiCr1.78-xMnx (x=0, 0.4, 0.6 and 0.8) have been measured by X-ray diffraction at room temperature as a function of the Mn content.

In order to obtain lighter storage systems one should concentrate on improving the ratio mass of hydride bed to mass of tank wall by screening lighter materials for the tank wall and developing hydrogen storage materials exhibiting both higher gravimetric and volumetric storage capacities.","downloadable_attachments":[{"id":44739532,"asset_id":13981488,"asset_type":"Work","always_allow_download":false}],"ordered_authors":[{"id":33024462,"first_name":"Thomas","last_name":"Klassen","domain_name":"hsu-hh","page_name":"TKlassen","display_name":"Thomas Klassen","profile_url":"https://hsu-hh.academia.edu/TKlassen?f_ri=21551","photo":"/images/s65_no_pic.png"},{"id":33060163,"first_name":"José","last_name":"Bellosta von Colbe","domain_name":"hzg","page_name":"JoséBellostaColbe","display_name":"José M Bellosta von Colbe","profile_url":"https://hzg.academia.edu/Jos%C3%A9BellostaColbe?f_ri=21551","photo":"/images/s65_no_pic.png"},{"id":32962861,"first_name":"Jose","last_name":"Bellosta von Colbe","domain_name":"hzg","page_name":"JoseBellostaVonColbe","display_name":"Jose M Bellosta von Colbe","profile_url":"https://hzg.academia.edu/JoseBellostaVonColbe?f_ri=21551","photo":"/images/s65_no_pic.png"}],"research_interests":[{"id":48,"name":"Engineering","url":"https://www.academia.edu/Documents/in/Engineering?f_ri=21551","nofollow":true},{"id":21551,"name":"Hydrogen Storage","url":"https://www.academia.edu/Documents/in/Hydrogen_Storage?f_ri=21551","nofollow":true},{"id":91424,"name":"Hydrogen Storage Materials","url":"https://www.academia.edu/Documents/in/Hydrogen_Storage_Materials?f_ri=21551","nofollow":true},{"id":104345,"name":"Hydrogen Energy","url":"https://www.academia.edu/Documents/in/Hydrogen_Energy?f_ri=21551","nofollow":true},{"id":260118,"name":"CHEMICAL SCIENCES","url":"https://www.academia.edu/Documents/in/CHEMICAL_SCIENCES?f_ri=21551"},{"id":344170,"name":"Storage system","url":"https://www.academia.edu/Documents/in/Storage_system?f_ri=21551"},{"id":1208732,"name":"Simulation Model","url":"https://www.academia.edu/Documents/in/Simulation_Model?f_ri=21551"}]}, }) } })();</script></ul></li></ul></div></div><div class="u-borderBottom1 u-borderColorGrayLighter"><div class="clearfix u-pv7x u-mb0x js-work-card work_41997833 coauthored" data-work_id="41997833" itemscope="itemscope" itemtype="https://schema.org/ScholarlyArticle"><div class="header"><div class="title u-fontSerif u-fs22 u-lineHeight1_3"><a class="u-tcGrayDarkest js-work-link" href="https://www.academia.edu/41997833/Wind_and_solar_hydrogen_for_the_potential_production_of_ammonia_in_the_state_of_Cear_a_e_Brazil">Wind and solar hydrogen for the potential production of ammonia in the state of Cear a e Brazil</a></div></div><div class="u-pb4x u-mt3x"><div class="summary u-fs14 u-fw300 u-lineHeight1_5 u-tcGrayDarkest"><div class="summarized">The main objective of this article is to analyze the feasibility of producing ammonia as main component for the synthesis of nitrogen fertilizers in the state of Cear a e Brazil.

However, TiFe is difficult to activate, usually requiring a thermal treatment above 400 ºC. A TiFeMn alloy milled for just 10 min in a 100 L industrial milling device showed excellent hydrogen storage properties without any thermal treatment. The as-milled TiFeMn alloy did not need any activation procedure and showed fast kinetic behavior and good cycling stability. Microstructural and morphological characterization of the as-received and as-milled TiFeMn alloys revealed that the material presents reduced particle and crystallite sizes, even after such short time of milling.

The refined microstructure of the as-milled TiFeMn is deemed to account for the improved hydrogen absorption-desorption properties.","downloadable_attachments":[{"id":65458021,"asset_id":44931877,"asset_type":"Work","always_allow_download":false}],"ordered_authors":[{"id":87212935,"first_name":"Julián","last_name":"Puszkiel","domain_name":"hzg","page_name":"JuliánPuszkiel","display_name":"Julián Puszkiel","profile_url":"https://hzg.academia.edu/Juli%C3%A1nPuszkiel?f_ri=21551","photo":"https://0.academia-photos.com/87212935/25644432/48597567/s65_juli_n.puszkiel.gif"},{"id":184148382,"first_name":"Hans Ulrich","last_name":"Benz","domain_name":"independent","page_name":"HansUlrichBenz","display_name":"Hans Ulrich Benz","profile_url":"https://independent.academia.edu/HansUlrichBenz?f_ri=21551","photo":"/images/s65_no_pic.png"}],"research_interests":[{"id":21551,"name":"Hydrogen Storage","url":"https://www.academia.edu/Documents/in/Hydrogen_Storage?f_ri=21551","nofollow":true},{"id":205228,"name":"Scale-Up","url":"https://www.academia.edu/Documents/in/Scale-Up?f_ri=21551","nofollow":true},{"id":245964,"name":"Industrial Application","url":"https://www.academia.edu/Documents/in/Industrial_Application?f_ri=21551","nofollow":true},{"id":376927,"name":"Hydrides","url":"https://www.academia.edu/Documents/in/Hydrides?f_ri=21551","nofollow":true},{"id":2748516,"name":"Mechanical Milling","url":"https://www.academia.edu/Documents/in/Mechanical_Milling?f_ri=21551"}]}, }) } })();</script></ul></li></ul></div></div><div class="u-borderBottom1 u-borderColorGrayLighter"><div class="clearfix u-pv7x u-mb0x js-work-card work_14805968 coauthored" data-work_id="14805968" itemscope="itemscope" itemtype="https://schema.org/ScholarlyArticle"><div class="header"><div class="title u-fontSerif u-fs22 u-lineHeight1_3"><a class="u-tcGrayDarkest js-work-link" href="https://www.academia.edu/14805968/Development_and_experimental_characterization_of_a_fuel_cell_powered_aircraft">Development and experimental characterization of a fuel cell powered aircraft</a></div></div><div class="u-pb4x u-mt3x"><div class="summary u-fs14 u-fw300 u-lineHeight1_5 u-tcGrayDarkest"><div class="summarized">This paper describes the characteristics and performance of a fuel cell powered unmanned aircraft.

The aircraft is novel as it is the largest compressed hydrogen fuel cell powered airplane built to date and is currently the only fuel cell aircraft whose design and test results are in the public domain. The aircraft features a 500 W polymer electrolyte membrane fuel cell with full balance of plant and compressed hydrogen storage incorporated into a custom airframe. Details regarding the design requirements, implementation and control of the aircraft are presented for each major aircraft system. The performances of the aircraft and powerplant are analyzed using data from flights and laboratory tests. The efficiency and component power consumption of the fuel cell propulsion system are measured at a variety of flight conditions. The performance of the aircraft powerplant is compared to other 0.5-1 kW-scale fuel cell powerplants in the literature and means of performance improvement for this aircraft are proposed.

Cryogenic pressure vessels can be fueled with ambient temperature compressed gaseous hydrogen (CGH 2 ), LH 2 or cryogenic hydrogen at elevated supercritical pressure (cryo-compressed hydrogen, CcH 2 ). When filled with LH 2 or CcH 2 , these vessels contain 2-3 times more fuel than conventional ambient temperature compressed H 2 vessels. LLNL has demonstrated fueling with LH 2 onboard two vehicles. The generation 2 vessel, installed onboard an H 2powered Toyota Prius and fueled with LH 2 demonstrated the longest unrefueled driving distance and the longest cryogenic H 2 hold time without evaporative losses. A third generation vessel will be installed, reducing weight and volume by minimizing insulation thickness while still providing acceptable thermal endurance. Based on its long experience with cryogenic hydrogen storage, BMW has developed its cryo-compressed hydrogen storage concept, which is now undergoing a thorough system and component validation to prove compliance with automotive requirements before it can be demonstrated in a BMW test vehicle.

Soon after the discovery of carbon nanotubes in 1991, different research groups succeeded in filling carbon nanotubes with some elements, and, therefore, the question arose of filling carbon nanotubes with hydrogen by possibly using new effects such as nano-capillarity. Subsequently, very promising experiments claiming high hydrogen storage capacities in different carbon nanostructures initiated enormous research activity. Hydrogen storage capacities have been reported that exceed the benchmark for automotive application of 6.5 wt% set by the U.S. Department of Energy. However, the experimental data obtained with different methods for various carbon nanostructures show an extreme scatter. Classical calculations based on physisorption of hydrogen molecules could not explain the high storage capacities measured at ambient temperature, and, assuming chemisorption of hydrogen atoms, hydrogen release requires temperatures too high for technical applications. Up to now, only a few calculations and experiments indicate the possibility of an intermediate binding energy. Recently, serious doubt has arisen in relation to several key experiments, causing considerable controversy. Furthermore, high hydrogen storage capacities measured for carbon nanofibers did not survive cross-checking in different laboratories. Therefore, in light of today&amp;#39;s knowledge, it is becoming less likely that at moderate pressures around room temperature carbon nanostructures can store the amount of hydrogen required for automotive applications.</div></div></div><ul class="InlineList u-ph0x u-fs13"><li class="InlineList-item logged_in_only"><div class="share_on_academia_work_button"><a class="academia_share Button Button--inverseBlue Button--sm js-bookmark-button" data-academia-share="Work/17342060" data-share-source="work_strip" data-spinner="small_white_hide_contents"><i class="fa fa-plus"></i><span class="work-strip-link-text u-ml1x" data-content="button_text">Bookmark</span></a></div></li><li class="InlineList-item"><div class="download"><a id="03382077d1e2f08d3f746f8b055278f7" rel="nofollow" data-download="{"attachment_id":42267030,"asset_id":17342060,"asset_type":"Work","always_allow_download":false,"track":null,"button_location":"work_strip","source":null,"hide_modal":null}" class="Button Button--sm Button--inverseGreen js-download-button prompt_button doc_download" href="https://www.academia.edu/attachments/42267030/download_file?st=MTczNzQzNDAwMyw4LjIyMi4yMDguMTQ2&s=work_strip"><i class="fa fa-arrow-circle-o-down fa-lg"></i><span class="u-textUppercase u-ml1x" data-content="button_text">Download</span></a></div></li><li class="InlineList-item"><ul class="InlineList InlineList--bordered u-ph0x"><li class="InlineList-item InlineList-item--bordered"><span class="InlineList-item-text">by <span itemscope="itemscope" itemprop="author" itemtype="https://schema.org/Person"><a class="u-tcGrayDark u-fw700" data-has-card-for-user="37045591" href="https://korea-kr.academia.edu/UrszulaDettlaffweglikowska">Urszula Dettlaff-weglikowska</a><script data-card-contents-for-user="37045591" type="text/json">{"id":37045591,"first_name":"Urszula","last_name":"Dettlaff-weglikowska","domain_name":"korea-kr","page_name":"UrszulaDettlaffweglikowska","display_name":"Urszula Dettlaff-weglikowska","profile_url":"https://korea-kr.academia.edu/UrszulaDettlaffweglikowska?f_ri=21551","photo":"https://0.academia-photos.com/37045591/18249284/18223856/s65_urszula.dettlaff-weglikowska.jpg"}</script></span></span></li><li class="js-paper-rank-work_17342060 InlineList-item InlineList-item--bordered hidden"><span class="js-paper-rank-view hidden u-tcGrayDark" data-paper-rank-work-id="17342060"><i class="u-m1x fa fa-bar-chart"></i><strong class="js-paper-rank"></strong></span><script>$(function() { new Works.PaperRankView({ workId: 17342060, container: ".js-paper-rank-work_17342060", });

Soon after the discovery of carbon nanotubes in 1991, different research groups succeeded in filling carbon nanotubes with some elements, and, therefore, the question arose of filling carbon nanotubes with hydrogen by possibly using new effects such as nano-capillarity. Subsequently, very promising experiments claiming high hydrogen storage capacities in different carbon nanostructures initiated enormous research activity. Hydrogen storage capacities have been reported that exceed the benchmark for automotive application of 6.5 wt% set by the U.S. Department of Energy. However, the experimental data obtained with different methods for various carbon nanostructures show an extreme scatter. Classical calculations based on physisorption of hydrogen molecules could not explain the high storage capacities measured at ambient temperature, and, assuming chemisorption of hydrogen atoms, hydrogen release requires temperatures too high for technical applications. Up to now, only a few calculations and experiments indicate the possibility of an intermediate binding energy. Recently, serious doubt has arisen in relation to several key experiments, causing considerable controversy. Furthermore, high hydrogen storage capacities measured for carbon nanofibers did not survive cross-checking in different laboratories. Therefore, in light of today\u0026amp;#39;s knowledge, it is becoming less likely that at moderate pressures around room temperature carbon nanostructures can store the amount of hydrogen required for automotive applications.","downloadable_attachments":[{"id":42267030,"asset_id":17342060,"asset_type":"Work","always_allow_download":false}],"ordered_authors":[{"id":37045591,"first_name":"Urszula","last_name":"Dettlaff-weglikowska","domain_name":"korea-kr","page_name":"UrszulaDettlaffweglikowska","display_name":"Urszula Dettlaff-weglikowska","profile_url":"https://korea-kr.academia.edu/UrszulaDettlaffweglikowska?f_ri=21551","photo":"https://0.academia-photos.com/37045591/18249284/18223856/s65_urszula.dettlaff-weglikowska.jpg"}],"research_interests":[{"id":48,"name":"Engineering","url":"https://www.academia.edu/Documents/in/Engineering?f_ri=21551","nofollow":true},{"id":923,"name":"Technology","url":"https://www.academia.edu/Documents/in/Technology?f_ri=21551","nofollow":true},{"id":2738,"name":"Renewable Energy","url":"https://www.academia.edu/Documents/in/Renewable_Energy?f_ri=21551","nofollow":true},{"id":3771,"name":"Hydrogen","url":"https://www.academia.edu/Documents/in/Hydrogen?f_ri=21551","nofollow":true},{"id":4748,"name":"Electrochemistry","url":"https://www.academia.edu/Documents/in/Electrochemistry?f_ri=21551"},{"id":5303,"name":"Carbon","url":"https://www.academia.edu/Documents/in/Carbon?f_ri=21551"},{"id":12842,"name":"Carbon Nanotube","url":"https://www.academia.edu/Documents/in/Carbon_Nanotube?f_ri=21551"},{"id":17733,"name":"Nanotechnology","url":"https://www.academia.edu/Documents/in/Nanotechnology?f_ri=21551"},{"id":21551,"name":"Hydrogen Storage","url":"https://www.academia.edu/Documents/in/Hydrogen_Storage?f_ri=21551"},{"id":27303,"name":"Fuel Cell","url":"https://www.academia.edu/Documents/in/Fuel_Cell?f_ri=21551"},{"id":39752,"name":"Adsorption","url":"https://www.academia.edu/Documents/in/Adsorption?f_ri=21551"},{"id":69542,"name":"Computer Simulation","url":"https://www.academia.edu/Documents/in/Computer_Simulation?f_ri=21551"},{"id":93298,"name":"Fossil Fuels","url":"https://www.academia.edu/Documents/in/Fossil_Fuels?f_ri=21551"},{"id":118582,"name":"Physical sciences","url":"https://www.academia.edu/Documents/in/Physical_sciences?f_ri=21551"},{"id":216113,"name":"Atmospheric pollution","url":"https://www.academia.edu/Documents/in/Atmospheric_pollution?f_ri=21551"},{"id":260118,"name":"CHEMICAL SCIENCES","url":"https://www.academia.edu/Documents/in/CHEMICAL_SCIENCES?f_ri=21551"},{"id":296798,"name":"Hydrogen Bonding","url":"https://www.academia.edu/Documents/in/Hydrogen_Bonding?f_ri=21551"},{"id":336385,"name":"Energy System","url":"https://www.academia.edu/Documents/in/Energy_System?f_ri=21551"},{"id":649537,"name":"Molecular Conformation","url":"https://www.academia.edu/Documents/in/Molecular_Conformation?f_ri=21551"},{"id":891610,"name":"Proton Exchange Membrane Fuel Cell","url":"https://www.academia.edu/Documents/in/Proton_Exchange_Membrane_Fuel_Cell?f_ri=21551"},{"id":1529889,"name":"Nanotubes Carbon","url":"https://www.academia.edu/Documents/in/Nanotubes_Carbon?f_ri=21551"}]}, }) } })();</script></ul></li></ul></div></div><div class="u-borderBottom1 u-borderColorGrayLighter"><div class="clearfix u-pv7x u-mb0x js-work-card work_56575047" data-work_id="56575047" itemscope="itemscope" itemtype="https://schema.org/ScholarlyArticle"><div class="header"><div class="title u-fontSerif u-fs22 u-lineHeight1_3"><a class="u-tcGrayDarkest js-work-link" href="https://www.academia.edu/56575047/Hydrogen_absorption_and_electrochemical_properties_of_Mg2Ni_type_alloys_synthesized_by_mechanical_alloying">Hydrogen absorption and electrochemical properties of Mg2Ni-type alloys synthesized by mechanical alloying</a></div></div><div class="u-pb4x u-mt3x"><div class="summary u-fs14 u-fw300 u-lineHeight1_5 u-tcGrayDarkest"><div class="summarized">Mg 2 Ni-type alloys, i.e., Mg 2 Ni, Mg 2 Ni 0.75 Cu 0.25 , Mg 2 Ni 0.6 Cu 0.4 and Mg 2 Ni 0.75 V 0.25 were synthesized by mechanical alloying and subsequent thermal treatment starting from a corresponding elemental powder mixture.

The catalytic activity of 8.2 Â 10 À6 mol-ethylcarbazole/g of metal/s and selectivity of 98% towards a fully hydrogen loaded product were recorded over 5 wt% ruthenium on alumina which was prepared by mild chemical reduction of ruthenium salt. Using this catalyst the theoretical capacity of hydrogen uptake (5.7 wt%) was obtained and the rate of the reaction and activation energy were estimated. Due to its potential high hydrogen storage capacity, this system could be a promising on-board storage candidate for mobile applications. The structures of reaction products and intermediates were identified using 2D NMR techniques. These structures were also predicted to be thermodynamically stable using density functional theory (DFT), matching well with the experimental observations. (S.C.

The experimental char-acterisation of trapping parameters in metals, which is required for an accurate simulation of hydrogen transport, is usually performed through the electropermeation test. In order to study grain size influence and grain boundary trapping during permeation, two modelling approaches are explored; a 1D Finite Element model including trap density and binding energy as input parameters and a polycrystalline model based on the assignment of a lower diffusivity and solubility to the grain boundaries. Samples of pure iron after two different heat treatments-950 • C for 40 min and 1100 • C for 5 min-are tested applying three consecutive rising permeation steps and three decaying steps. Experimental results show that the finer grain microstructure promotes a diffusion delay due to grain boundary trapping. The usual methodology for the determination of trap densities and binding energies is revisited in which the limiting diluted and saturated cases are considered. To this purpose, apparent diffusivities are fitted including also the influence of boundary conditions and comparing results provided by the constant concentration with the constant flux assumption. Grain boundaries are char-acterised for pure iron with a binding energy between 37.8 and 39.9 kJ/mol and a low trap density but it is numerically demonstrated that saturated or diluted assumptions are not always verified, and a univocal determination of trapping parameters requires a broader range of charging conditions for permeation. The relationship between surface parameters, i.e. charging current, recombination current and surface concentrations, is also studied showing that trapping phenomena are stronger during the diluted steps and that recombination currents are much higher than the steady state obtained flux.</div></div></div><ul class="InlineList u-ph0x u-fs13"><li class="InlineList-item logged_in_only"><div class="share_on_academia_work_button"><a class="academia_share Button Button--inverseBlue Button--sm js-bookmark-button" data-academia-share="Work/44545220" data-share-source="work_strip" data-spinner="small_white_hide_contents"><i class="fa fa-plus"></i><span class="work-strip-link-text u-ml1x" data-content="button_text">Bookmark</span></a></div></li><li class="InlineList-item"><div class="download"><a id="ab7b9e2cd3265ff98f89af858fac4329" rel="nofollow" data-download="{"attachment_id":64994310,"asset_id":44545220,"asset_type":"Work","always_allow_download":false,"track":null,"button_location":"work_strip","source":null,"hide_modal":null}" class="Button Button--sm Button--inverseGreen js-download-button prompt_button doc_download" href="https://www.academia.edu/attachments/64994310/download_file?st=MTczNzQzNDAwMyw4LjIyMi4yMDguMTQ2&s=work_strip"><i class="fa fa-arrow-circle-o-down fa-lg"></i><span class="u-textUppercase u-ml1x" data-content="button_text">Download</span></a></div></li><li class="InlineList-item"><ul class="InlineList InlineList--bordered u-ph0x"><li class="InlineList-item InlineList-item--bordered"><span class="InlineList-item-text">by <span itemscope="itemscope" itemprop="author" itemtype="https://schema.org/Person"><a class="u-tcGrayDark u-fw700" data-has-card-for-user="15486899" href="https://oxford.academia.edu/EmilioMart%C3%ADnezPa%C3%B1eda">Emilio Martínez Pañeda</a><script data-card-contents-for-user="15486899" type="text/json">{"id":15486899,"first_name":"Emilio","last_name":"Martínez Pañeda","domain_name":"oxford","page_name":"EmilioMartínezPañeda","display_name":"Emilio Martínez Pañeda","profile_url":"https://oxford.academia.edu/EmilioMart%C3%ADnezPa%C3%B1eda?f_ri=21551","photo":"https://0.academia-photos.com/15486899/4180616/4868342/s65_emilio.mart_nez_pa_eda.png"}</script></span></span></li><li class="js-paper-rank-work_44545220 InlineList-item InlineList-item--bordered hidden"><span class="js-paper-rank-view hidden u-tcGrayDark" data-paper-rank-work-id="44545220"><i class="u-m1x fa fa-bar-chart"></i><strong class="js-paper-rank"></strong></span><script>$(function() { new Works.PaperRankView({ workId: 44545220, container: ".js-paper-rank-work_44545220", });

The experimental char-acterisation of trapping parameters in metals, which is required for an accurate simulation of hydrogen transport, is usually performed through the electropermeation test. In order to study grain size influence and grain boundary trapping during permeation, two modelling approaches are explored; a 1D Finite Element model including trap density and binding energy as input parameters and a polycrystalline model based on the assignment of a lower diffusivity and solubility to the grain boundaries. Samples of pure iron after two different heat treatments-950 • C for 40 min and 1100 • C for 5 min-are tested applying three consecutive rising permeation steps and three decaying steps. Experimental results show that the finer grain microstructure promotes a diffusion delay due to grain boundary trapping. The usual methodology for the determination of trap densities and binding energies is revisited in which the limiting diluted and saturated cases are considered. To this purpose, apparent diffusivities are fitted including also the influence of boundary conditions and comparing results provided by the constant concentration with the constant flux assumption. Grain boundaries are char-acterised for pure iron with a binding energy between 37.8 and 39.9 kJ/mol and a low trap density but it is numerically demonstrated that saturated or diluted assumptions are not always verified, and a univocal determination of trapping parameters requires a broader range of charging conditions for permeation. The relationship between surface parameters, i.e. charging current, recombination current and surface concentrations, is also studied showing that trapping phenomena are stronger during the diluted steps and that recombination currents are much higher than the steady state obtained flux.","downloadable_attachments":[{"id":64994310,"asset_id":44545220,"asset_type":"Work","always_allow_download":false}],"ordered_authors":[{"id":15486899,"first_name":"Emilio","last_name":"Martínez Pañeda","domain_name":"oxford","page_name":"EmilioMartínezPañeda","display_name":"Emilio Martínez Pañeda","profile_url":"https://oxford.academia.edu/EmilioMart%C3%ADnezPa%C3%B1eda?f_ri=21551","photo":"https://0.academia-photos.com/15486899/4180616/4868342/s65_emilio.mart_nez_pa_eda.png"}],"research_interests":[{"id":3771,"name":"Hydrogen","url":"https://www.academia.edu/Documents/in/Hydrogen?f_ri=21551","nofollow":true},{"id":21551,"name":"Hydrogen Storage","url":"https://www.academia.edu/Documents/in/Hydrogen_Storage?f_ri=21551","nofollow":true},{"id":250889,"name":"Hydrogen Embrittlement","url":"https://www.academia.edu/Documents/in/Hydrogen_Embrittlement?f_ri=21551","nofollow":true},{"id":1403897,"name":"Permeation Study","url":"https://www.academia.edu/Documents/in/Permeation_Study?f_ri=21551","nofollow":true}]}, }) } })();</script></ul></li></ul></div></div><div class="u-borderBottom1 u-borderColorGrayLighter"><div class="clearfix u-pv7x u-mb0x js-work-card work_66186378" data-work_id="66186378" itemscope="itemscope" itemtype="https://schema.org/ScholarlyArticle"><div class="header"><div class="title u-fontSerif u-fs22 u-lineHeight1_3"><a class="u-tcGrayDarkest js-work-link" href="https://www.academia.edu/66186378/A_Proposal_for_Water_Transportation_by_a_Hydrogen_Energy_System_A_Feasibility_Study_for_Kazakhstan">A Proposal for Water Transportation by a Hydrogen Energy System -A Feasibility Study for Kazakhstan</a></div></div><div class="u-pb4x u-mt3x"><div class="summary u-fs14 u-fw300 u-lineHeight1_5 u-tcGrayDarkest"><div class="summarized">This study examines the use of hydrogen as an energy carrier for spreading renewable energy and mitigating environmental problems, and proposes a system for carrying clean water together with hydrogen.

Practical simulations were carried out assuming the present conditions of Kazakhstan. The capital and most other large cities are located both far from clean water sources, and areas with plenty of sunshine. The proposed model consists of hydrogen generation by solar-powered electrolysis, transportation of hydrogen by railways and electric power generation using fuel cells in cities. The fuel cells also generate clean liquid water. This paper proposes a hydrogen transportation system by railway, where Ti-based hydrogen storage alloys fabricated with readily available metals in Kazakhstan are used.

The general cracking pattern of the cylinder, the fractographic features, and the stress analysis results were all indicative of an internal gaseous detonation. Accordingly, several specific characteristics of detonation-driven fracture of closed-end cylindrical tubes were identified. These characteristics were analyzed through detailed examinations of the fracture surfaces, cracking patterns, and dynamic stress analysis of the cylinder using a transient analytical model. Based on the size and location of special markings found on the shear lips, and using the time duration of flexural waves, the crack growth increments and speed were computed. Consequently, the basic features of the gaseous detonation and the composition of the original gas mixture were identified. The results indicated that the detonation of a low-pressure oxygen-rich mixture of hydrogen and oxygen was the cause of this failure.

All of the carbon atoms are in sp 3 hybridization forming a hexagonal network and the hydrogen atoms are bonded to carbon on both sides of the plane in an alternating manner. Graphane is predicted to be stable with a binding energy comparable to other hydrocarbons such as benzene, cyclohexane, and polyethylene.

The compound that we call graphane is a fully saturated hydrocarbon derived from a single graphene sheet with formula CH. All of the carbon atoms are in sp 3 hybridization forming a hexagonal network and the hydrogen atoms are bonded to carbon on both sides of the plane in an alternating manner. Graphane is predicted to be stable with a binding energy comparable to other hydrocarbons such as benzene, cyclohexane, and polyethylene. We discuss possible routes for synthesizing graphane and potential applications as a hydrogen storage material and in two dimensional electronics.","downloadable_attachments":[{"id":4717663,"asset_id":790334,"asset_type":"Work","always_allow_download":false}],"ordered_authors":[{"id":629594,"first_name":"AJAY","last_name":"S","domain_name":"mg","page_name":"AJAYS","display_name":"AJAY

On basis of these facts, nanocomposite materials can be considered as strong candidates for hydrogen storage. In the present work, we report a novel conducting polymeric nanocomposite material for hydrogen storage. Conducting polymer-based nanocomposites were modified using carbon nanotubes as filler material. This further increased the porous structure of the nanocomposite and the number of binding sites, which in turn enhances the hydrogen storage capacity. Additionally, fine aluminum powder was added to the polymeric nanocomposite, which further increased the hydrogen sorption of the material. The modified conducting polymeric nanocomposites were characterized with various analytical techniques including FTIR, DSC, TGA and SEM. Adsorption and desorption experiments are conducted using a Sieverts-type volumetric PCT instrument. Further experiments are in progress to understand the hydrogen storage mechanism in the proposed conducting polymer nanocomposites. ᭧</div></div></div><ul class="InlineList u-ph0x u-fs13"><li class="InlineList-item logged_in_only"><div class="share_on_academia_work_button"><a class="academia_share Button Button--inverseBlue Button--sm js-bookmark-button" data-academia-share="Work/7417365" data-share-source="work_strip" data-spinner="small_white_hide_contents"><i class="fa fa-plus"></i><span class="work-strip-link-text u-ml1x" data-content="button_text">Bookmark</span></a></div></li><li class="InlineList-item"><div class="download"><a id="49c2f506f2bb1007bfa0bd008ab4c9c9" rel="nofollow" data-download="{"attachment_id":48494863,"asset_id":7417365,"asset_type":"Work","always_allow_download":false,"track":null,"button_location":"work_strip","source":null,"hide_modal":null}" class="Button Button--sm Button--inverseGreen js-download-button prompt_button doc_download" href="https://www.academia.edu/attachments/48494863/download_file?st=MTczNzQzNDAwMyw4LjIyMi4yMDguMTQ2&s=work_strip"><i class="fa fa-arrow-circle-o-down fa-lg"></i><span class="u-textUppercase u-ml1x" data-content="button_text">Download</span></a></div></li><li class="InlineList-item"><ul class="InlineList InlineList--bordered u-ph0x"><li class="InlineList-item InlineList-item--bordered"><span class="InlineList-item-text">by <span itemscope="itemscope" itemprop="author" itemtype="https://schema.org/Person"><a class="u-tcGrayDark u-fw700" data-has-card-for-user="13150766" href="https://floridapolytechnic.academia.edu/SeshaSrinivasan">Sesha Srinivasan</a><script data-card-contents-for-user="13150766" type="text/json">{"id":13150766,"first_name":"Sesha","last_name":"Srinivasan","domain_name":"floridapolytechnic","page_name":"SeshaSrinivasan","display_name":"Sesha Srinivasan","profile_url":"https://floridapolytechnic.academia.edu/SeshaSrinivasan?f_ri=21551","photo":"https://0.academia-photos.com/13150766/11736041/35658247/s65_sesha.srinivasan.jpg"}</script></span></span></li><li class="js-paper-rank-work_7417365 InlineList-item InlineList-item--bordered hidden"><span class="js-paper-rank-view hidden u-tcGrayDark" data-paper-rank-work-id="7417365"><i class="u-m1x fa fa-bar-chart"></i><strong class="js-paper-rank"></strong></span><script>$(function() { new Works.PaperRankView({ workId: 7417365, container: ".js-paper-rank-work_7417365", });

On basis of these facts, nanocomposite materials can be considered as strong candidates for hydrogen storage. In the present work, we report a novel conducting polymeric nanocomposite material for hydrogen storage. Conducting polymer-based nanocomposites were modified using carbon nanotubes as filler material. This further increased the porous structure of the nanocomposite and the number of binding sites, which in turn enhances the hydrogen storage capacity. Additionally, fine aluminum powder was added to the polymeric nanocomposite, which further increased the hydrogen sorption of the material. The modified conducting polymeric nanocomposites were characterized with various analytical techniques including FTIR, DSC, TGA and SEM. Adsorption and desorption experiments are conducted using a Sieverts-type volumetric PCT instrument. Further experiments are in progress to understand the hydrogen storage mechanism in the proposed conducting polymer nanocomposites.
