AB  - Desalination is an important method to take full advantage of the sea water to produce fresh water. However, the systems or devices reported previously still have the limitations in the energy supply and portability when used in some specific application scenarios, such as island and remote coastal area. In this paper, a multi-function desalination system is proposed, which could provide fresh water, electrical energy, and even the cold energy based on the hydrolysis reaction of hydride and fuel cell water recovery. Besides, the system could be modified to increase the flexibility of the system operation to satisfy the various energy demands under different conditions. A lumped parameter model of the proposed system is developed to evaluate the system performance. The results show that the fuel cell helps to increase the absolute humidity of the wet air by 15.5% and to increase the water production by condensing the wet air by 1.8 times compared with simple water harvest from the ambient environment. The modified system demonstrates more stable performance of the water production than the original desalination system, which means that the modified system is less affected by the parameter variation. The maximum water production of the kW level system could achieve 11.10 kg/h. Comparing with the previous reports, the unit power consumption of the modified system could reach the lowest level (about 880 Wh/kg), showing the promising water production performance of the system developed in this work.

AB  - Advanced biogas power generation technology has been attracting attentions, which contributes to the waste disposal and the mitigation of greenhouse gas emissions. This work proposes and models a novel biogas-fed hybrid power generation system consisting of solid oxide fuel cell, water gas shift reaction, thermal swing adsorption and proton exchange membrane fuel cell (SOFC-WGS-TSA-PEMFC). The thermodynamic, exergetic, and thermo-economic analyses of this hybrid system for power generation were conducted to comprehensively evaluate its performance. It was found that the novel biogas-fed hybrid system has a gross energy conversion efficiency of 68.63% and exergy efficiency of 65.36%, indicating high efficiency for this kind of hybrid power technology. The market sensitivity analysis showed that the hybrid system also has a low sensitivity to market price fluctuation. Under the current subsidy level for the distributed biogas power plant, the levelized cost of energy can be lowered to 0.02942 $/kWh for a 1 MW scale system. Accordingly, the payback period and annual return on investment can reach 1.4 year and about 20%, respectively. These results reveal that the proposed hybrid system is promising and economically feasible as a distributed power plant, especially for the small power scale (no more than 2 MW).

AB  - LiAlH4 is a promising material for hydrogen storage, having the theoretical gravimetric density of 10.6 wt% H2. In order to decrease the temperature where hydrogen is released, we investigated the catalytic influence of Fe2O3 on LiAlH4 dehydrogenation, as a model case for understanding the effects transition oxide additives have in the catalysis process. Quick mechanochemical synthesis of LiAlH4 + 5 wt% Fe2O3 led to the significant decrease of the hydrogen desorption temperature, and desorption of over 7 wt%H2 in the temperature range 143–154 °C. Density functional theory (DFT)-based calculations with Tran-Blaha modified Becke-Johnson functional (TBmBJ) address the electronic structure of LiAlH4 and Li3AlH6. 57Fe Mössbauer study shows the change in the oxidational state of iron during hydrogen desorption, while the 1H NMR study reveals the presence of paramagnetic species that affect relaxation. The electron transfer from hydrides is discussed as the proposed mechanism of destabilization of LiAlH4 + 5 wt% Fe2O3. © 2021 Hydrogen Energy Publications LLC

AB  - Advanced efficient energy conversion technology using clean alternative fuel contributes to the alleviation of the energy crisis and environmental deterioration. In this situation, a novel methanol utilization technology for power generation based on hybrid fuel cell system is proposed in this work. The hybrid system consists of a solid oxide fuel cell (SOFC), a gas processing unit (GP) and a proton exchange membrane fuel cell (PEMFC). Thermodynamic analysis of the system shows that the energy conversion efficiency and exergy efficiency are both higher than the previously reported standalone or hybrid energy systems using methanol as fuel, which are 66.2% and 54.2% respectively. Besides, no recirculation ratio of anode off-gas and moderate fuel utilization of about 0.5 are suggested for the SOFC component to balance the power distribution and improve the efficiency. Afterwards, this hybrid fuel cell system is also investigated from thermo-economic and techno-economic perspectives. Take Northwest China as a case, the 1 MWe methanol-fed power plant has a specific electric energy cost of 0.5594 CNY/kWh, much lower than the methanol steam reforming-PEMFC power plant (2.4 CNY/kWh). At the same time, the sensitivity analyses reveal that the cost of the hybrid power system is not sensitive to the market price fluctuation. With financial subsidies for existing renewable power plants, the payback period can be shortened to 1.4 year and the annual return on investment is about 3.58%. These results reveal that this two-stage fuel cell hybrid system is a kind of efficient and economically methanol to power conversion technology, especially for small power scale. © 2021 Elsevier Ltd

AB  - In order to develop clean and efficient energy conversion technology, a novel combined cooling, heating and power (CCHP) system using biomass as fuel is proposed in this work. The proposed CCHP system consists of biomass gasification unit, solid oxide fuel cell (SOFC), engine power generation unit and absorption refrigeration unit. Thermodynamic model of the CCHP system is developed for the parametric and exergy analyses to evaluate the performance. The parametric analysis shows that increasing the steam to biomass ratio or the SOFC fuel utilization factor helps to improve the electrical efficiency, while the increase of air equivalent ratio has a negative effect. The exergy analysis shows that the two units of biomass gasification and engine power generation have the largest exergy destruction ratio, which is 46.9% and 16.8% under the biomass flux of 500 kg·h−1. This is because these two units involve in high-temperature thermochemical reaction process, resulting in relatively large exergy destruction. Besides, the tradeoff between maximum exergy efficiency, CCHP efficiency and minimum total annual cost is conducted by multi-objective optimization. Through optimization, the system could reach the high CCHP efficiency of 75% and net electrical efficiency of 52%, as well as the low total annual cost of 410 k$ simultaneously. This work could provide the basic design idea, and high-efficiency and low-cost operation strategy for the practical application of the proposed novel biomass-fueled CCHP poly-generation system.

AB  - In order to uncover the inner working mechanism and performance of solid oxide fuel cell (SOFC) with biomass gasification syngas as fuel, a two dimensional SOFC multi-physical field model is established. This study makes up for the deficiency that the previous studies of coupling biomass gasification unit and SOFC stack mostly stay at the system level. The results show that the SOFC fueled by the syngas produced from gasification of biomass with steam as the agent has the best performance. The peak power density could achieve approximately 10240 W m−2. With the improvement of operating temperature, the peak power density of SOFC will be increased. At the temperature of 1123 K, the peak power density could achieve about 15128 W m−2. The average reaction rate of water gas shift (WGS) reaction is −29.73 mol m−3 s−1 when the operating temperature is 1123 K. This indicates that the WGS reaction will proceed in reverse direction at high temperatures, thereby reducing the hydrogen concentration. In addition, increase in the anode flux and decrease in the cell length lead to the increase of SOFC current density. In general, this work could provide guidance for the optimization and practical application of SOFC using biomass syngas as fuel.

AB  - The impact of boron doping on MgH2 bonding mechanism, hydrogen diffusion and desorption was calculated using density functional theory (DFT). Atomic interactions in doped and non-doped system and its influence on hydrogen and vacancy diffusion were studied in bulk hydride. Slab calculations were performed to study hydrogen desorption energies from (110) boron doped surface and its dependence on the surface configuration and depth position. To study kinetics of hydrogen diffusion in boron vicinity and hydrogen molecule desorption activation energies from boron doped and non-doped (110) MgH2 surface Nudged Elastic Band (NEB) method was used. Results showed that boron forms stronger, covalent bonds with hydrogen causing the destabilization in its first and second coordination. This leads to lower hydrogen desorption energies and improved hydrogen diffusion, while the impact on the energy barriers for H2 desorption from hydride (110) surface is less pronounced. © 2019 Hydrogen Energy Publications LLC

The morphology, particle and crystallite size were studied as a function of milling speed, vial's volume, and ball-to-powder ratio. The vial's fill level, the number, and type of milling balls and additive's content kept constant. Changes in morphology and microstructure were correlated to desorption properties of materials. Higher milling speed reduced particle size but, there is no significant crystallite size reduction. On the other hand, additive distribution is similar regardless of the energy input. It has been noticed that different energy input on milling blend, which is the result of combined effects of above-mentioned factors, reflects on desorption temperature but not on the kinetics of desorption.

AB  - This paper proposes a novel autothermal-equilibrium metal hydride reactor as the hydrogen source for the fuel cell power system, which employs phase change material (PCM) to recycle the hydrogen storage heat. A three-dimensional model of the metal hydride reactor coupled with a salt hydrate PCM for heat recovery is developed. Based on the model, the effects of key operating and design parameters on the reactor are investigated for performance optimization, including operating pressure, melting temperature, latent heat and thermal conductivity of PCM. Through the parametric analysis, it is found that increasing the operating pressure is beneficial to accelerate the absorption reaction. The average reaction fraction at 2400 s is increased by 24% with the pressure increasing from 6 to 10 bar. The moderate melting temperature and the thermal conductivity of the PCM that is comparable to that of metal hydride bed contribute to the improvement of hydrogen storage efficiency. Using this kind of hydrogen source reactor in a fuel cell power system, stable hydrogen storage efficiency of approximately 60% in the experiment is presented. In addition, no obvious performance deterioration of the power system occurs after ten cycles.

AB  - In this work, the model of metal hydride reactor coupled with phase change material (PCM) as heat management is modified to describe the heat and mass transfer behaviors of the continuous hydrogen absorption/desorption processes better. Through the experimental validation, the modified model is proven to be more accurate than the traditional model. Based on the proposed model, the performance of the metal hydride reactor is further optimized by the parametric analysis, property and configuration modification. The results show that the metal hydride reactor achieves a hydrogen storage efficiency of 47% at the phase change temperature of 42 °C, which is higher than at 35 and 49 °C. By adding expanded graphite into PCM, the hydrogen storage efficiency can increase up to about 72%, which is higher than the previously reported efficiency of 69%. This is because of the enhanced heat transfer between metal hydride and PCM. Accordingly, the hydrogen absorption time is significantly shortened to no more than 5 min. In addition, it is suggested to operate the reactor in the hydrogen desorption pressure of 2–8 bar and the temperature of 32–58 °C for the improved performance, when this kind of reactor is applied in the fuel cell power system as hydrogen source.

abstract = "In this work, the model of metal hydride reactor coupled with phase change material (PCM) as heat management is modified to describe the heat and mass transfer behaviors of the continuous hydrogen absorption/desorption processes better. Through the experimental validation, the modified model is proven to be more accurate than the traditional model. Based on the proposed model, the performance of the metal hydride reactor is further optimized by the parametric analysis, property and configuration modification. The results show that the metal hydride reactor achieves a hydrogen storage efficiency of 47% at the phase change temperature of 42 °C, which is higher than at 35 and 49 °C. By adding expanded graphite into PCM, the hydrogen storage efficiency can increase up to about 72%, which is higher than the previously reported efficiency of 69%. This is because of the enhanced heat transfer between metal hydride and PCM. Accordingly, the hydrogen absorption time is significantly shortened to no more than 5 min. In addition, it is suggested to operate the reactor in the hydrogen desorption pressure of 2–8 bar and the temperature of 32–58 °C for the improved performance, when this kind of reactor is applied in the fuel cell power system as hydrogen source.",

AB  - Paper presents detailed studies of local and electronic structure around Fe in Cd0.97Fe0.03Te, Cd0.98Fe0.02Te0.97Se0.03 and Cd0.99Fe0.01Te0.91S0.09 multinary chalcogenides by means of X–ray absorption fine structure (XAFS), X–ray magnetic circular dichroism (XMCD) and electron paramagnetic resonance (EPR) measurements. In addition, electronic consequences of Fe incorporation into CdTe semiconductor host were studied by means of first principles calculations. In order to improve accuracy of the calculated total energies, the band gaps and the band edge positions, special attention is paid to the treatment of exchange–correlation interaction and the description of highly localized Fe 3d–states. Also, the Bader theory of the topological properties of the electron charge density is used to access details of the nature, strength and distribution of the (next) nearest neighbour bonds. Local and electronic structure around Fe in Cd0.97Fe0.03Te and Cd0.98Fe0.02Te0.97Se0.03 systems have been found to exhibit similar characteristics, since the first coordination sphere around Fe comprises four Te atoms located at approximately the same distance. In Cd0.99Fe0.01Te0.91S0.09 system, however, local bimodal distribution of distances has been revealed, with one Fe–Te bond replaced with much shorter Fe–S bond, resulting in much stronger crystal–field. Along with the crystal field effect, the spin–orbit interaction has proven to play decisive role in determining the nature of Fe doped CdTe systems. While the systems with higher Fe concentrations (25 at.%) are intrinsic insulators, in systems with only 3.125 at.% Fe one spin channel contributes to the density of states at the Fermi level, which makes them suitable for spin selective electronic transport applications. © 2018 Elsevier B.V.

AB  - This review deals with the destabilization methods for improvement of storage properties of metal hydrides. Both theoretical and experimental approaches were used to point out the influence of various types of defects on structure and stability of hydrides. As a case study, Mg, and Ni based hydrides has been investigated. Theoretical studies, mainly carried out within various implementations of DFT, are a powerful tool to study mostly MgH 2 based materials. By providing an insight on metal-hydrogen bonding that governs both thermodynamics and hydrogen kinetics, they allow us to describe phenomena to which experimental methods have a limited access or do not have it at all: to follow the hydrogen sorption reaction on a specific metal surface and hydrogen induced phase transformations, to describe structure of phase boundaries or to explain the impact of defects or various additives on MgH 2 stability and hydrogen sorption kinetics. In several cases theoretical calculations reveal themselves as being able to predict new properties of materials, including the ways to modify Mg or MgH 2 that would lead to better characteristics in terms of hydrogen storage. The influence of ion irradiation and mechanical milling with and without additives has been discussed. Ion irradiation is the way to introduce a well-defined concentration of defects (Frankel pairs) at the surface and sub-surface layers of a material. Defects at the surface play the main role in sorption reaction since they enhance the dissociation of hydrogen. On the other hand, ball-milling introduce defects through the entire sample volume, refine the structure and thus decrease the path for hydrogen diffusion. Two Severe Plastic Deformation techniques were used to better understand the hydrogenation/dehydrogenation kinetics of Mg- and Mg 2 Ni-based alloys: Equal-Angular-Channel-Pressing and Fast-Forging. Successive ECAP passes leads to refinement of the microstructure of AZ31 ingots and to instalment therein of high densities of defects. Depending on mode, number and temperature of ECAP passes, the H-sorption kinetics have been improved satisfactorily without any additive for mass H-storage applications considering the relative speed of the shaping procedure. A qualitative understanding of the kinetic advanced principles has been built. Fast-Forging was used for a “quasi-instantaneous” synthesis of Mg/Mg 2 Ni-based composites. Hydrogenation of the as-received almost bi-phased materials remains rather slow as generally observed elsewhere, whatever are multiple and different techniques used to deliver the composite alloys. However, our preliminary results suggest that a synergic hydrogenation / dehydrogenation process should assist hydrogen transfers from Mg/Mg 2 Ni on one side to MgH 2 /Mg 2 NiH 4 on the other side via the rather stable a-Mg 2 NiH 0.3 , acting as in-situ catalyser. © 2019 Wiley-VCH Verlag GmbH & Co.

AB  - Processes taking place during hydrogen desorption from MgH2 thin films were investigated in as-prepared samples and samples modified by argon ion irradiation. Irradiation was used to produce well-defined defects with depth distribution. It was shown that the size, shape, and concentration of Mg nuclei formed during hydrogen desorption from MgH2 thin films depend on the characteristics and distribution of the induced defects. In as-prepared samples the shape of Mg nuclei is spherical, while in irradiated samples, it is highly irregular. Variations in sample colour were observed during hydrogen desorption and before the creation of Mg nuclei. DFT calculations showed that the observed variations in the optical properties of samples can be explained by changes in MgH2 electronic structure -the appearance of an H-vacancy band within the MgH2 energy gap.

In as-prepared samples the shape of Mg nuclei is spherical, while in irradiated samples, it is highly irregular. Variations in sample colour were observed during hydrogen desorption and before the creation of Mg nuclei. DFT calculations showed that the observed variations in the optical properties of samples can be explained by changes in MgH2 electronic structure -the appearance of an H-vacancy band within the MgH2 energy gap.

AB  - Structural and electronic properties, oxidation and aging effect of electrochemically (EC) synthesized magnetite nanopowders (NPs) are studied by means of X-ray diffraction (XRD), X-ray absorption fine structure (XAFS) and X-ray magnetic circular dichroism (XMCD). The obtained results enabled to get a direct insight into the structure and electronic properties of Fe immediate surrounding and to elucidate the influence of preparation conditions on stoichiometry of NPs and their stability in ambient conditions. All investigated NPs are produced as nonestoichiometric Fe3-delta O4 oxide phases, with the lattice constant and the Fe2+/Fe3+ ratio both in-between the values for bulk maghemite and magnetite. NPs synthesized under smaller current density (J = 200 mA/dm(2)) are more magnetite-alike, whereas larger current density (J = 1000 mA/dm(2)) has led to formation of NPs closer to maghemite. Oxidation of magnetite-like NPs is slower, although in the course of time particles agglomerate and oxide penetrates into the core. Maghemite-like NPs oxidize much faster and the oxide layer which is confined close to the particles surface protects the core from further oxidation. In all NPs the fist coordination around Fe is pretty stable against both temperature and oxidation process. The temperature change from 293 K to 20 K considerably affects the second coordination around Fe, which is most likely a consequence of the Verwey transition present in all investigated samples.

Given that the oxide additives show the good impact on desorption properties, mechanical milling of MgH2 with addition of 5, 10 and 15% wt. WO3 was performed. The microstructure and morphology of composites were analysed by XRD, PSD and SEM and correlated to hydrogen desorption properties which have been investigated by DSC. The results have shown that WO3 has a positive effect on the desorption kinetics as well as on the change of the desorption mechanism.

The microstructural properties of composites were characterized by means of X-ray diffraction (XRD), Raman spectroscopy, Scanning electron microscopy (SEM), Particle size analysis (PSD), while sorption behaviour was followed by differential scanning calorimetry (DSC) and Sievert measurements. Results have shown that although desorption temperature reduction is moderate; there is a substantial improvement in hydrogen sorption kinetics. The complete desorption of pure MgH2 at elevated temperature takes place in more than 30 min while the composite fully desorbs in less than 2 min even at lower temperatures. It has been shown that the metastable gamma-MgH2 phase and the point defects have a decisive role in desorption process only in the first sorption cycle, while the second and the subsequent sorption cycles are affected by microstructural and morphological characteristics of the composite.

AB  - Hydrogen desorption properties of MgH2 ball milled with two different TiO2 polymorphs, rutile and anatase, were studied. Structural characterization has been done by X-ray diffraction (XRD) analysis, particle size analysis (PSD) and scanning electron microscopy (SEM). The mechanism of desorption and the apparent activation energy for desorption were investigated by applying isoconversional kinetic analysis of DTA spectra, while desorbed species were followed by TPD coupled with mass spectroscopy. It has been demonstrate that the addition of rutile TiO2 significantly decrease the apparent activation energy for desorption (E-des(a)), while addition of anatase titania has negligible influence on E-des(a). Such behaviour could be explained in terms of the same crystal structure of rutile TiO2 and MgH2. Further, the mechanism of desorption changes from Avrami-Erofeev n = 3 for pure MgH2 to Avrami Erofeev n = 4 for composite materials. Copyright (c) 2016, Hydrogen Energy Publications, LLC.

AB  - The aim of the present study was to synthesize a composite of raw interstratified montmorillonite-kaolinite clay (Mt-K) with TiO2 as an additive by mechanochemical activation and investigate its usability as low-cost adsorbent for simultaneous removal of heavy metals from acidic aqueous solutions. The composite synthesized with amorphous TiO2 (TiO(2,)a) showed a significantly better removal ability of heavy metals from highly acidic solutions (pH = 2.0-4.0) compared with the Mt-K milled for an optimum period of time of 19 h (Mt-K,m) and composite synthesized with crystalline TiO2 (TiO(2,)c). As both of the composites showed the same morphologies, the same distribution of TiO2 particles on the clay matrix, the same particle size distribution (PSD) dependencies and point of zero charge (pH(PZC)) values, it has to be noticed that the difference in the adsorption behavior lies only in the different crystalline forms of the additive, i.e. TiO2 that was used for the composite preparation. It has been shown that 20% of TiO(2,)a was the optimal amount of an additive in the composite to achieve improved adsorption ability. (C) 2014 Elsevier B.V. All rights reserved.

AB  - Desorption of hydrogen atoms from the (110) surface of rutile magnesium hydride (MgH2) was investigated using density functional theory (DFT) and pseudopotential method. System was represented by (110) (2x2) slab MgH2 supercell with 12 atomic layers along the z-axis. The H-desorption was modeled by the successive release of the four two-fold bonded H atoms from the (110) surface of MgH2. Dependence of the H-desorption energy on number and configuration of remaining surface hydrogen atoms has been determined. The features of the H atoms diffusion from the bulk towards the surface have been investigated, too. The results suggest that decrease in number of surface H atoms generally lowers the H-desorption energy in each desorption step and that both the H-H and the Mg-H interatomic interactions strongly influence the H-desorption process. The hydrogen vacancy formation energy in the first three sub-surface layers also exhibits a pronounced dependence on concentration. These findings lead to the conclusion that tendency of the MgH2 (110) surface to preserve a maximum possible surface H concentration in its most stable configuration is the limiting factor for the H-desorption kinetics. In principle, the obtained results allow us to determine preferred paths of surface and subsurface H-diffusion for a wide range of H concentrations and the principle features of the MgH2 dehydrogenation process, at least for the H-rich region. Being rather comprehensive, the approach is applicable for other metal hydrides, as well. Copyright (C) 2013, Hydrogen Energy Publications, LLC. Published by Elsevier Ltd. All rights reserved.

AB  - The hydrogen desorption properties of vacant MgH2 structure were
investigated both experimentally and theoretically. Ion irradiation by Ar8+
and Xe8+ ions were used to induce structural changes in MgH2. Hydrogen
desorption properties were investigated by temperature programmed
desorption (TPD). To obtained deeper insight in structural changes during
desorption theoretical calculations were performed using DFT approach
within Abinit code. Results showed that there are several mechanisms
involved in desorption process, which depend on defect concentration, their
position and their interaction and ordering. It has been demonstrated that the
changes in near-surface area play the crucial role in desorption kinetics.

AB  - The hydrogen desorption properties and kinetics of MgH2-VO2 composite prepared by mechanical milling of MgH2 and VO2 have been investigated. Structural characterization of produced nanocomposite was done by X-ray powder diffraction (XRD), particle size analysis and scanning electron microscopy (SEM). The structure and morphology of the composite have been correlated with hydrogen desorption properties investigated by differential thermal analysis (DTA). It has been shown that short mechanical milling of nanostructured VO2 and MgH2 leads to decrease of hydrogen desorption temperature of MgH2 by 80 K. The mechanism of desorption has been changed from phase boundary reaction, spherical symmetry for untreated MgH2 to phase boundary reaction, cylindrical symmetry for the composite material. The activation energy for desorption has been reduced by adding VO2 ceramics as a catalyst. (C) 2012 Elsevier Ltd and, Techna Group S.r.l. All rights reserved.
