Conception and numerical simulation of heat and mass transfer in a solid state hydrogen storage reactor

Abstract

Nowadays energy storage seems to be a vital point in any new energy paradigm. It has become an important and strategic issue, to ensure the energetic sufficiency of humanity. Indeed, hydrogen storage in solids has been proved and revealed as clean and efficient energy storage. Moreover, it can be thought as a seriously considered solution to enable renewable energy to be a part of our quotidian life. To achieve storing hydrogen in solid form, the present study aimed to concepts and simulates a solid-state hydrogen storage reactor (tank). An investigation of the parameters influencing the hydrogen storage performance is carried out. Meanwhile, to understand the physical phenomenon taking place during the storage of hydrogen, a 2D numerical modelling for a metal hydrides-based in hydrogen reactor is presented. A strong coupling between energy balance, kinetic law, as well as a mass momentum balance at sorbent bed temperature under a non-uniform pressure was resolved based on finite element method. The temporal evolutions of pressure, the raising temperature in the bed during the hydriding process as well as the impact of the hydrogen supply pressure within the tank are analysed and validated by comparison with the experimental work in literature, a good agreement is obtained. From an industrial point of view, this study can be used to design and manufacture an optimal solid-state hydrogen storage reactor.

Sensors and energy harvesters based on (1–x)PMN-xPT piezoelectric ceramics

“…When the piezoelectric materials are deformed or stressed, a voltage appears across the material. The electrical and mechanical behavior can be modeled by two constitutive equation (1) of longitudinal mode [23]:…”

“…However, the mechanical to mechanical coupling effect would indeed result in an additional damping of the host structure due to the energy conversion between the host structure and the harvester (Fig. 1), and thus a decreased output power [23].…”

Advanced materials for energy harvesting, storage, sensing and environmental engineering

“…The present edition is a continuation of the three previous 2016, 2017 and 2018 editions [1][2][3]. It practically includes works on similar themes such as energy transfer and storage [4][5][6], materials for energy and photonics [7][8][9][10], solar thermal and photovoltaic [11,12]. The theme of sensors and the thermal and vibration energy harvesting using piezoelectric and pyroelectric effects received a particular attention [13][14][15].…”

“…This Topical issue to the European Physical Journal À Applied Physics on Materials for Energy Harvesting, Storage, Sensing and Environmental Engineering intends to dress an updated and equilibrated picture of the multidisciplinary connections between energy and man-agement, as previous issues did [10][11][12][13]. This year's issue covers multidisciplinary areas of applied research into which Physics has a say: energy transfer, conversion and storage [14][15][16][17], fluid mechanics and microfluidics [18,19], materials [20][21][22]. Modelling and simulation complement the issue by providing understanding and prediction to experimental situations, with various approaches at multiple scales: nano, micro, meso and macroscopic [23][24][25][26][27].…”

“…Dans ce sens, l'activité scientifique a massivement bénéficié cette année de sa production passée et présente en termes de [10][11][12][13]. Le numéro de cette année couvre des domaines multidisciplinaires de recherche appliquée dans lesquels la physique a son mot à dire: transfert, conversion et stockage d'énergie [14][15][16][17], mécanique des fluides et microfluidique [18,19], matériaux [20][21][22]. La modélisation et la simulation complètent la problématique en permettant de comprendre et de prédire les situations expérimentales, avec différentes approches à plusieurs échelles: nano, micro, méso et macroscopique [23][24][25][26][27].…”
