As the world evolves, so does the energy demand. The storage of hydrogen using metal hydrides shows great promise due to the ability to store and deliver energy on demand while achieving higher volumetric density and safer storage conditions compared with traditional storage options such as compressed gas or liquid hydrogen. Research is typically performed on lab-sized samples and tanks and shows great potential for large scale applications. However, the effects of scale-up on the metal hydride’s performance are relatively less investigated. Studies performed so far on both materials, and hydride-based storage tanks show that the scale-up can significantly impact the system’s capacity, kinetics, and sorption properties. The findings presented in this review suggest areas of further investigation in order to implement metal hydrides in real scale applications.

Thermal conduction capability of metal hydrides can be enhanced by 400 ~ 500% through pelletizing the metal hydride powder after a well-controlled copper-coating treatment. In this paper, pelletized LaNi5 metal hydride is studied to evaluate its heat transfer performance and hydrogen absorption rate. In order to analyze the transient heat transfer and hydriding reaction, numerical simulations are carried out based on a multiple-physics modeling. The reactor temperature variation and the dimensionless mass of absorbed hydrogen are plotted for different hydrogen gas supply pressures. The results are compared with the conventional powder-type metal hydride reactor.

Metal hydrides are promising hydrogen storage materials widely studied and accepted by many authorities, but still, it has not reached the set goal. In this work, polymer-based carbon particles along with metal hydride materials are proposed as a storage medium for hydrogen. Metal hydride particles were integrated into a polymeric matrix with carbon particles to improve the thermal stability and hydrogen storage capacity. Some physical properties, morphological effects, and thermal conductivity values of the polymeric composite were investigated using X-ray diffraction (XRD), Fourier Transform Infrared Spectroscopy (FTIR), and scanning electron microscopy (SEM). The test results indicated that metal hydrides and carbon particles were well integrated into the polymeric structure, which could drastically affect the hydrogen storage capacity of the polymeric composites for applications in the transportation industry.

Energy production, distribution, and storage remain paramount to a variety of applications that reflect on our daily lives, from renewable energy systems, to electric vehicles and consumer electronics. Hydrogen is the sole element promising high energy, emission-free, and sustainable energy, and metal hydrides in particular have been investigated as promising materials for this purpose. While offering the highest gravimetric and volumetric hydrogen storage capacity of all known materials, metal hydrides are plagued by some serious deficiencies, such as poor kinetics, high activation energies that lead to high operating temperatures, poor recyclability, and/or stability, while environmental considerations related to the treatment of end-of-life fuel disposal are also of concern. A strategy to overcome these limitations is offered by nanotechnology, namely embedding reactive hydride compounds in nanosized supports such as graphene. Graphene is a 2D carbon material featuring unique mechanical, thermal, and electronic properties, which all recommend its use as the support for metal hydrides. With its high surface area, excellent mechanical strength, and thermal conductivity parameters, graphene can serve as the support for simple and complex hydrides as well as RHC (reactive hydride composites), producing nanocomposites with very attractive hydrogen storage properties.

Complex metal hydrides such as sodium aluminohydride (NaAlH4) and sodium borohydride (NaBH4) are solid-state hydrogen-storage materials with high hydrogen capacities. They can be used in combination with fuel cells as a hydrogen source thus enabling longer operation times compared with classical metal hydrides. The most important point for a wide application of these materials is the reversibility under moderate technical conditions. At present, only NaAlH4 has favorable thermodynamic properties and can be employed as a thermally reversible means of hydrogen storage. By contrast, NaBH4 is a typical non-reversible complex metal hydride; it reacts with water to produce hydrogen.

Metal hydrides are a class of materials that can absorb and release large amounts of hydrogen. They have a wide range of potential applications, including their use as a hydrogen storage medium for fuel cells or as a hydrogen release agent for chemical processing. While being a technology that can supersede existing energy storage systems in manifold ways, the use of metal hydrides also faces some challenges that currently hinder their widespread applicability. As the effectiveness of heat transfer across metal hydride systems can have a major impact on their overall efficiency, an affluent description of more efficient heat transfer systems is needed. The literature on the subject has proposed various methods that have been used to improve heat transfer in metal hydride systems over the years, such as optimization of the shape of the reactor vessel, the use of heat exchangers, phase change materials (PCM), nano oxide additives, adding cooling tubes and water jackets, and adding high thermal conductivity additives. This review article provides a comprehensive overview of the latest, state-of-the-art techniques in metal hydride reactor design and heat transfer enhancement methodologies and identifies key areas for future researchers to target. A comprehensive analysis of thermal management techniques is documented, including performance comparisons among various approaches and guidance on selecting appropriate thermal management techniques. For the comparisons, the hydrogen adsorption time relative to the reactor size and to the amount of hydrogen absorbed is studied. This review wishes to examine the various methods that have been used to improve heat transfer in metal hydride systems and thus aims to provide researchers and engineers working in the field of hydrogen storage with valuable insights and a roadmap to guide them to further explore the development of effective thermal management techniques for metal hydrides.

The application of an innovative heat-storage system with metal hydride to building air-conditioning is investigated. Metal hydrides characteristically generate heat through the absorption process and absorb heat through the desorption process, allowing the development of a new air-conditioning system without chlorofluorocarbons. The trial system is composed of two heat-storage vessels, a “shell-and-tube-type” heat exchanger built with heat transfer fins and filled with metal hydride, and a compressor equipped for hydrogen transfer. The purpose of heat storage is to decrease the difference between electric power demand in the daytime and at night. This system transfers hydrogen using electric power at night and reverses the reaction during the day using only the pressure difference between two heat-storage vessels. The experimental results indicate that heat-storage is attained within a limited time, and the heat-storage quantity is 13.5MJ, which is sufficient for the heat capacity to cool the 10m2 room for 3hr. The stored heat per unit metal hydride volume is 289MJ∕m3, which is sufficiently higher than the conventional system using water or ice. In addition, the coefficient of performance of the system is 2.44.

Significant progress in the installation of renewable energy requires the improvement of energy production and storage technologies. Hydrogen energy storage systems based on reversible metal hydride materials can be used as an energy backup system. Metal hydride hydrogen storage systems are distinguished by a high degree of safety of their use, since hydrogen is stored in a solid phase, a high volumetric density of stored hydrogen, and the possibility of long-term storage without losses. A distinctive feature of metal hydride materials is the reversible and selective absorption and release of high-purity hydrogen. This paper presents experimental studies of LaNi5-based metal hydride materials with a useful hydrogen capacity of 1.0–1.3 wt.% H2 with equilibrium pressures of 0.025 - 0.05 MPa and 0.1 - 1.2 MPa at moderate temperatures of 295 - 353 K for the hydrogen purification systems and hydrogen long-term storage systems, respectively. The applicability of metal hydride technologies for renewable energy sources as energy storage systems in the form of hydrogen is also shown.

Hydrogen technology has become essential to fulfill our mobile and stationary energy needs in a global low–carbon energy system. The non-renewability of fossil fuels and the increasing environmental problems caused by our fossil fuel–running economy have led to our efforts towards the application of hydrogen as an energy vector. However, the development of volumetric and gravimetric efficient hydrogen storage media is still to be addressed. LiBH4 is one of the most interesting media to store hydrogen as a compound due to its large gravimetric (18.5 wt.%) and volumetric (121 kgH2/m3) hydrogen densities. In this review, we focus on some of the main explored approaches to tune the thermodynamics and kinetics of LiBH4: (I) LiBH4 + MgH2 destabilized system, (II) metal and metal hydride added LiBH4, (III) destabilization of LiBH4 by rare-earth metal hydrides, and (IV) the nanoconfinement of LiBH4 and destabilized LiBH4 hydride systems. Thorough discussions about the reaction pathways, destabilizing and catalytic effects of metals and metal hydrides, novel synthesis processes of rare earth destabilizing agents, and all the essential aspects of nanoconfinement are led.

Annotation:

This thesis describes the preparation and characterisation of potential ‘modular’ solid state hydrogen storage solutions for on-board applications. The systems investigated throughout this work are based on reactions between light weight hydroxides and hydrides. In many senses light metal hydroxides can be seen as attractive candidates for hydrogen storage: they are low cost, present negligible toxicity and it is not possible to poison the fuel cell with decomposition products, unlike in nitrogen or boron containing systems. However, as the dehydrogenation products are the respective oxides, the major drawback of such systems lays in the fact the thermodynamics of rehydrogenation are not favourable for onboard applications. Hence, the system must be considered as a ‘charged module’, where the regeneration is performed ex-situ. Dehydrogenation can be achieved through reaction with light metal hydrides such as LiH or MgH2. A wide range of ‘modular’ release systems can be studied, however the most interesting in terms of theoretical gravimetric capacity, kinetics and thermodynamics within reasonable temperature range (RT - 350°C) use magnesium and lithium hydroxide and their hydrate forms. The present work focuses on the full investigation of three main systems: · Mg(OH)2 – MgH2 system · Mg(OH)2 – LiH system · LiOH(·H2O) – MgH2 system (both anhydrous and monohydrate LiOH were used) Mixtures of hydroxides and hydrides were prepared by manually grinding stoichiometric amounts of the starting materials. Further, nanostructuring the reactants was investigated as a means to control the dehydrogenation reaction and enhance the kinetics and thermodynamics of the process. Nanostructured Mg(OH)2 and LiOH(·H2O) have been successfully obtained using both novel and conventional synthetic routes. Reduction of the particle size of both hydrides was effectively achieved by mechanically milling the bulk materials. As detailed throughout Chapters 3, 4 and 5, promising results were obtained when employing nanosized reactants. The onset temperatures of hydrogen release were decreased and the overall systems performances enhanced. Particularly interesting results were obtained for the LiOH – MgH2 system, which exhibit a dramatic decrease of the onset temperature of H2 release of nearly 100 K when working with milled and nanostructured materials with respect to bulk reagents. All systems were characterised mainly by Powder X-ray diffraction (PXD) and simultaneous thermogravimetric analysis (TG-DTA) mass spectroscopy (MS). TG-DTA2 MS experiments were performed to obtain information on the onset and peak temperature of hydrogen release, weight loss percentage and nature and amount of the gases evolved during the reaction. Ex-situ PXD studies have been performed for each system in order to try and identify any intermediate species forming during the dehydrogenation process and ultimately propose a mechanism of H2 release. Since two fundamentally different types of reaction pathway could be proposed for the Mg(OH)2 – LiH system, powder neutron diffraction (PND) was employed for following the reaction in-situ. Developing a complete model of the dehydrogenation process in terms of mechanistic steps was found to be pivotal in order to understand and enhance such systems further.

The hydrogen storage properties of a metal are highly dependent on its structure, including the crystal structures of the metal and the hydride, the defect structures of the metal and the relationship between hydrogen cycling and these properties. The aim of this project was to establish a greater understanding of the link between hysteresis and the structure of the metal, investigated by conducting in-situ diraction experiments on both palladium and LaNi5 and their hydrides. Dislocations have a signicant impact on the pressure hysteresis in metal hydrides, but the exact link between them is poorly understood. A first experiment was performed aiming to increase the understanding of pressure hysteresis by investigating the annealing characteristics of dislocations in palladium hydride. Dislocations are created in the first traversal of the two-phase region in hydrogen cycled palladium but it is not clear what happens to the dislocations subsequent to the first cycle. An experiment was carried out to measure the density of dislocations while annealing in the phase, annealing under vacuum, and hydrogen cycling at increasing and decreasing temperatures. The dislocation density was measured using high resolution in-situ neutron diraction. It was found that annealing under vacuum and annealing in the phase produced the same result, but the dislocation density decreased much faster with temperature when the sample was hydrogen-cycled. Therefore the phase transformation signicantly aided in the removal of dislocations from the sample. It is suggested that the dislocations are gliding at the front of the advancing phase boundary, resulting in the removal of dislocations once the absorption/desorption is complete and the dislocations have reached the edge of a grain. This means that dislocations can be created and removed simultaneously during hydrogen cycling, resulting in a stable dislocation density. Dislocations gliding at the front of the phase boundary can also accommodate the strain of the transformation, explaining the reduced hysteresis on subsequent cycles compared to the first cycle.

In an experimental stand [1] for investigation of properties of hydrogen accumulating the materials investigated a new type of reactor cleaning and storage of hydrogen. The applicability of hydrogen purging through metal hydride beds for the purification from nonpoisoning admixtures is studied experimentally. The main characteristics of the process together with the main technical barriers of the proposed technology are defined. Specially designed stainless steel continuous flow reactor filled with LaFe0.1Mn0.3Ni4.8 intermetallic compound is tested at variable inlet hydrogen/inert gas composition with measuring mass flow, pressure, temperature and hydrogen content at the outlet both for charging and discharging mode. The estimations of hydrogen losses and purification capacity show certain advantages of the studied technology in comparison with PSA-like mode [1], especially from the point of view of operation regime simplification. The evident process slow-down observed in the experiment is connected with saturation of metal hydride porous bed by hydrogen and with temperature increase due to high thermal effect at sorption (~ 40 kJ/mole Н2). The ways for heat and mass transfer optimization together with the range of applicability of the method for fine hydrogen purification are described and discussed.

The main objective of this study was to advance kinetic performances of formation and decomposition of magnesium hydride by design strategies which include high energy ball milling in hydrogen (HRBM), in combination with the introduction of catalytic/dopant additives. In this regard, the transformation of Mg → MgH2 by high energy reactive ball milling in hydrogen atmosphere (HRBM) of Mg with various additives to yield nanostructured composite hydrogen storage materials was studied using in situ pressure-temperature monitoring that allowed to get time-resolved results about hydrogenation behaviour during HRBM. The as-prepared and re-hydrogenated nanocomposites were characterized using XRD, high-resolution SEM and TEM, as well as measurements of the mean particle size. Dehydrogenation performances of the nanocomposites were studied by DSC / TGA and TDS; and the re-hydrogenation behaviour was investigated using Sieverts volumetric technique.

Ni - MH batteries have superior properties which are long cycle life, low maintenance, high power, light weight, good thermal performance and configurable design. Hydrogen storage alloys play a dominant role in power service life of a Ni - MH battery and determining the electrochemical properties of the battery. LaNi5, belonging to the CaCu5 crystal structure type, satisfy many of the properties. The most important property of LaNi5 is fast hydrogen kinetics. Recently, CaNi5, belonging to same crystal type, has taken some attention due to its low cost, higher hydrogen storage capacity, good kinetic properties. However, the main restriction of its use is its very low cycle life. The aim of the study is to obtain a more stable structure providing higher cycle life by the addition of different alloying elements. In this study, the effect of sixteen alloying elements (Mn, Sm, Sn, Al, Y, Cu, Si, Zn, Cr, Mg, Fe, Dy, V, Ti, Hf and Er) on cycle life was investigated. Sm, Y, Dy, Ti, Hf and Er were added for replacement of Ca and Mn, Sn, Al, Cu, Si, Zn, Cr, Mg, Fe and V were added for replacement of Ni. Alloys were produced by vacuum casting and heat treating followed by ball milling. The cells assembled, using the produced active materials as anode, which were cycled for charging and discharging. As a result, replacement of Ca with Hf, Ti, Dy and Er, and replacement of Ni with Si and Mn were observed to show better cycle durability rather than pure CaNi5.

Modelling and simulation are essential tools for concept evaluation and for predicting the performance of a hybrid energy system, since prototyping and testing each candidate design for such a complex system would almost always be prohibitively cumbersome, expensive and time consuming. To meet the modelling and simulation objectives, the various components of the system (sources, storage, loads, and converters) need to be characterised and modelled in a tractable way. The tuning of the models to reflect the actual system components is a key milestone in this process and requires reliable and comprehensive experimental data. Furthermore, environmental conditions such as ambient temperature may have a significant impact on the performance, which has to be taken into account. The complexity of hybrid energy systems and their dependence on embedded control software increases the difficulty in predicting interactions among the various components and subsystems. A modelling environment that can model not only the components but also control algorithms (such as Matlab/Simulink, Homer etc.) is therefore advantageous. Effective diagnosis of faults in an installed system also presents a challenge, because of the interactions between the components and the control system. Modelling may play an important role in diagnosis of the operating components. For example, running an electrolyser model and comparing actual electrolyser operating variables with those obtained from the model may help to diagnose a fault in the real electrolyser. This thesis focuses on modelling the principal components of hybrid solar energy systems that include energy storage in the form of hydrogen: a large photovoltaic array subject to manufacturer’s variability and temperature inhomogeneity; two types of electrolyser as commonly found in hydrogen energy systems; a metal-hydride hydrogen storage tank; a fuel cell. Attention is given here to building physics-based component models with minimum empiricism and to critically analysing the state of the art in modelling such components. The models have been realised in Simulink, so that they are mutually compatible and can be linked into a whole of system model. All the models were validated against experimental data and performed at least as well as models found in the literature. The thesis is based on six papers, four already published and two submitted.

AbstractSolid-state hydrogen storage is gradually becoming an effective way for the large-scale storage and transportation of hydrogen energy. Magnesium hydride (MgH2) has become a promising candidate among solid-state hydrogen storage materials due to its high hydrogen storage density, low cost and good safety. However, ambiguous H-Mg bond weakening mechanism of various catalysts on MgH2 hinders the development of novel catalysts for MgH2 dehydrogenation. To overcome this problem, we applied the model catalyst, single-atom catalyst with accurately characterizable coordination structure, to understand the interaction between catalyst and MgH2 surface through spin-polarized density-functional theory calculation. We constructed heterogeneous interface structures between single-atom catalysts and MgH2 surface including nine kinds of transition metal atoms. The interaction between single-atom catalysts and MgH2 surface has been well explored through bond length, electron localization function, charge density difference and crystal orbital Hamiltonian population, providing the intrinsic information of H-Mg bond weakening mechanism over single-atom catalysts. This work can establish the foundational guide for the design of novel dehydrogenation catalysts.

Directed Energy Weapon (DEW) systems in a pulse operation mode dissipate excessively large, transient waste heat because of their inherent inefficiencies. The heat storage system can store such a pulsed heat load not relying on oversized systems and dissipate the stored heat over time after the pulse operation. A compressor-driven metal hydride heat storage system was developed for efficient, compact heat storage and dissipation of the transient heat from the DEW systems. The greater volumetric heat storage capacity of metal hydride material was realized into more compact design than conventional Phase Change Material (PCM) systems. Other exclusive advantages of the metal hydride system were fast thermal response time and active heat pumping capability required for precision temperature control and on-demand cooling. This paper presented the operating principle and heat storage performance results of the compressor-driven metal hydride heat storage system through system modeling and prototype testing. The modeling and test results showed that the metal hydride system can store the average heat of 4.4kW during the heat storage period of 250 seconds and release the stored heat during the subsequent regeneration period of 900 seconds.

Over the past two years, key issues associated with the development of realistic metal hydride storage systems have been identified and studied at Purdue University’s Hydrogen Systems Laboratory, part of the Energy Center at Discovery Park. Ongoing research projects are aimed at the demonstration of a prototype large-scale metal hydride tank that achieves fill and release rates compatible with current automotive use. The large-scale storage system is a prototype with multiple pressure vessels compatible with 350 bar operation. Tests are conducted at the Hydrogen Systems Lab in a 1000 ft2 laboratory space comprised of two test cells and a control room that has been upgraded for hydrogen service compatibility. The infrastructure and associated data acquisition and control systems allow for remote testing with several kilograms of high-pressure reversible metal hydride powder. Managing the large amount of heat generated during hydrogen loading directly affects the refueling time. However, the thermal management of hydride systems is problematic because of the low thermal conductivity of the metal hydrides (∼ 1 W/m-K). Current efforts are aimed at optimizing the filling-dependent thermal performance of the metal hydride storage system to minimize the refueling time of a practical system. Combined heat conduction within the metal hydride and the enhancing material particles, across the contacts of particles and within the hydrogen gas between non-contacted particles plays a critical role in dissipating heat to sustain high reaction rates during refueling. Methods to increase the effective thermal conductivity of metal hydride powders include using additives with substantially higher thermal conductivity such as aluminum, graphite, metal foams and carbon nanotubes. This paper presents the results of experimental studies in which various thermal enhancement materials are added to the metal hydride powder in an effort to maximize the effective thermal conductivity of the test bed. The size, aspect ratio, and intrinsic thermal conductivity of the enhancement materials are taken into account to adapt heat conduction models through composite nanoporous media. Thermal conductivity and density of the composite materials are measured and enhancement metrics are calculated to rate performance of composites. Experimental results of the hydriding process of thermally enhanced metal hydride powder are compared to un-enhanced metal hydride powder and to model predictions. The development of the Hydrogen Systems Laboratory is also discussed in light of the lessons learned in managing large quantities of metal hydride and high pressure hydrogen gas.

Palladium is capable of storing a large atomic percent of hydrogen at room temperature and allows for hydrogen to diffuse with a high mobility. These unique properties make it an efficient storage medium for hydrogen and hydrogen isotopes, such as tritium, a byproduct of nuclear reaction. Palladium thus can be used for applications where fast diffusion and large storage density are important. Better understanding of molecular level phenomena such as hydride phase transformation in the metal and the effect of defects in the materials provides clues to designing metal hydrides that perform better. Atomic simulations are useful in the evaluation of palladium-hydrogen systems as changes in composition can be more easily explored than with experiments. In this paper, we present the palladium hydride potentials to investigate and identify the relevant physical mechanisms necessary to describe the absorption of hydrogen within a metal lattice.

High power solid state laser systems operating in a pulse mode dissipate the transient and excessively large waste heat from the laser diode arrays and gain material. The heat storage option using Phase Change Materials (PCMs) has been considered to manage such peak heat loads not relying on oversized systems for real-time cooling. However, the PCM heat storage systems suffer from the low heat storage densities and poor thermal conductivities of the conventional PCMs, consequently requiring large PCM volumes housed in thermal conductors such as aluminum or graphite foams. We developed a high performance metal hydride heat storage system for efficient and passive acquisition, storage, transport and dissipation of the transient, high heat flux heat from the high power solid state laser systems. The greater volumetric heat storage capacity of metal hydrides than the conventional PCMs can be translated into very compact systems with shorter heat transfer paths and therefore less thermal resistance. Other exclusive properties of the metal hydride materials consist of fast thermal response and active cooling capability required for the precision temperature control and transient high heat flux cooling. This paper discusses the operating principle and heat storage performance results of the metal hydride heat storage system through system analysis and prototype testing. The results revealed the superior heat storage performance of the metal hydride system to a conventional PCM system in terms of temperature excursion and system volume requirement.

Pelletized Porous Metal Hydride (PMH) was investigated in order to assess its thermal capability for energy storage/transfer applications. Metal hydrides have been known as promising materials for hydrogen storage systems, heat storage systems, and thermal devices, thanks to their nearly reversible reaction characteristics during the hydrogen absorbing and desorbing processes. The conventional powder-type metal hydrides however have a relatively low thermal conductivity, which is responsible for low heat generation. In the present study three representative metal hydrides, LaNi5, Ca0.6Mm0.4Ni5, and LaNi4.75Al0.25, metal hydride powders were coated with thin copper and pressed at 3,000 psig with metal additives in order to improve the thermal conductivity. This pelletizing process does not require the use of an organic binder and additional processes such as sintering under high pressure. The pelletized PMH compacts employing the copper coating exhibit higher thermal conductivity compared to raw metal hydride powders. However, pelletizing may deteriorate the permeability of the PMH compacts, lowering mass transfer of hydrogen. Therefore, the permeability must be observed to verify whether it meets the required level for suitable applications. Measurements were performed by varying copper fractions and plotted against the upstream/downstream pressure differential. Darcy’s equation in conjunction with an ideal gas assumption was used to calculate the permeability of a rigid wall design. This investigation reveals that rising copper content is accompanied with decreases in permeability. Permeability values for most samples tested in this study were found to be larger than the desirable level, 5 × 10−15 m2. Additionally, the thermal performance of the LaNi5 PMH compacts was tested by calculating and comparing the heat generation of the PMH pellets and powders filled reactors during the hydrogen absorption process in water bath medium.

Metal hydrides are promising hydrogen storage materials with potential for practical use in a passenger car. To be a viable hydrogen storage option, metal hydride heat transfer behavior must be well understood and accounted for. As such, the thermal properties of the metal hydride are measured and compiled to assess this behavior. These properties include thermal conductivity, specific heat, and thermal diffusivity. The transient plane source (TPS) method was selected primarily due to a high level of versatility, including customization for high pressure hydrogen environments. To perform this measurement, a TPS 2500 S thermal property analyzer by the Hot Disk Company was employed. To understand the measurement and analysis process of the TPS method, two different sample materials were evaluated at ambient conditions. These samples included a stainless steel pellet and an inactivated (non-pyrophoric) metal hydride pellet. Thermal conductivity and thermal diffusivity of these samples were measured using the TPS method. The thermal property measurements are compared to the data available in the literature (stainless steel) and the data obtained using laser flash method (metal hydride). The improvements needed to successfully implement the TPS method are discussed in detail.

Thermal storage in an important operational aspect of a solar thermal system which enables it to deliver power or energy when there is no sunlight available. Current thermal storage systems in solar thermal systems work based on transferring the generated heat from sunlight to a thermal mass material in an insulated reservoir and then withdraw it during dark hours. Some common thermal mass materials are stone, concrete, water, pressurized steam, phase changing materials, and molten salts. In the current paper, a hybrid thermal energy storage system which is based on two metal hydrides is proposed for a solar thermal system. The two hydrides which are considered for this system are magnesium hydride and lanthanum nickel. Although metal hydride Energy Storage Systems (ESS) suffer from slow response time which restricts them as a practical option for frequency regulation, off peak shaving and power supply stabilization; they can still demonstrate significant flexibility and good energy capacity. These specifications make them good candidates for thermal energy storage which are applicable to any capacity of a solar thermal system just by changing the size of the ESS unit.

Reversible metal hydrides are ideal vehicular hydrogen storage materials for the realization of on-board filling. Systems utilizing metal hydrides with high hydrogen release pressure (> 3 bar at -30 °C) can provide excellent cold-start capability. Although the required hydrogen filling pressure will also be high accordingly (> 100 bar), high-pressure (HP) metal hydride (MH) systems can store 20% to 50% more hydrogen in the void space between hydride particles in addition to the hydrogen absorbed by the metal alloys. To maintain a sufficiently high hydriding driving force during filling, it is very important to keep the MH temperature below a desirable level (85 °C). This issue becomes more important when the systems operate at high pressures, because the stress limits of materials for the container and other components decrease with increasing temperature. Efficient thermal management is needed to dissipate the large amount of heat produced during the initial rapid compression process (< 20 seconds) and the subsequent fast hydriding process (< 5 minutes). In this paper, thermal management design and analysis of a bench-scale rectangular-shaped HPMH module is reported. This module is approximately 1/70 of a vehicle-scale hydrogen storage tank. The modular approach provides flexibility to apply the knowledge obtained in this study to vehicle-scale designs. A typical AB2 HPMH is used as the hydrogen storage material. During the hydrogen filling process, the time-averaged volumetric heat release rate is approximately 3 MW/m3. Inner coolant passages are adopted to remove the heat. Through a scaling analysis of the energy conservation equation, the results indicate that thermal conduction in the metal hydride bed and convection in the coolant passages are both important factors. For the test module under development, finned tubes in conjunction with two-phase convection have been designed to meet the cooling requirements. Fin designs (material, thickness and spacing) have been evaluated using 3D numerical analysis. The knowledge learned from theoretical and numerical analyses is used to guide the construction of the HPME module, and hydrogen filling tests will be conducted soon.

Hydride formation in metals is a widely studied and applied phenomenon necessary to transition to clean energy solutions and various technological applications. We focus on three perspective applications of these materials, namely near-ambient hydrogen storage, hydrogen storage compressor materials, and alkali metal conversion electrodes, to demonstrate acceleration in the research achieved by utilizing a data-driven approach. Graph neural network was developed using a transfer learning approach from the MEGNet model and data related to the thermodynamics of hydride formation obtained in experimental work. Based on the crystal structure and composition as input features, we apply the MetalHydrideEnth model developed in our previous work to predict hydride formation enthalpy in intermetallic compounds. In this work, we focus on demonstrating how this approach, combined with available crystal information obtained from density functional theory calculations, can be applied for fast and extensive searches of novel metal hydride materials, having in mind the above-listed applications.
