Harvested from ORCID Public Data FileCristina Prieto in OpenAIREAbstractCurrent concentrated solar power (CSP) plants that operate at the highest temperature use molten salts as both heat transfer fluid (HTF) and thermal energy storage (TES) medium. Molten salts can reach up to 565°C before becoming chemically unstable and highly corrosive. This is one of the higher weaknesses of the technology. Solid particles have been proposed to overcome current working temperature limits, since the particle media can be stable for temperatures close to 1000°C. This work presents a review of solid particles candidates to be used as HTF and TES in CSP plants in open receivers. In addition, the interactions between solid particles with major system components are described in this review, for example, with TES system or heat exchanger. The parameters and properties of solid particles are identified from the material science point of view explaining their nature and the relation to the power plant efficiency and lifetime durability. Finally, future development is proposed; such as material selection according to each specific design, materials characterization, or durability test.

Harvested from ORCID Public Data FileA. Inés Fernández in OpenAIREThermal energy constitutes up to 90% of global energy budget, centering on heat conversion, transmission, and storage; therefore, the technology for harvesting solar energy worth to be developed. One of them is the concentrated solar power (CSP) solar towers where sun-tracking heliostats reflect solar radiation to the top of a tower where the receiver is located. The great advantage of CSP over other renewable energy sources is that energy storage is feasible, particularly when the heat transfer fluid (HTF) is also used as thermal energy storage (TES) material which is the case of solid particles. A lot of development efforts are under way for achieving commercial direct solar solid-particle systems. Solid particle systems for transferring high temperature thermal energy are purposed for increasing the efficiency of these systems when converting heat into electric power. This review recapitulates the concept of these systems taking into account the main receiver designs, particle conveyance, particle storage systems and components, the heat exchanger, and the main challenges that must be overcome to split this technology as a commercial one, especially from the materials availability point of view. This review summarizes the actual status of the use of solid particles for TES and as HTF for CSP Tower, and condenses all the available information and classifies them considering the main functional parts and remarking the current research in each part as well as the future challenging issues.

Harvested from ORCID Public Data FileSegarra Rubí, Mercè in OpenAIREDurability and reliability of solid particles to be used in concentrating solar power tower plants is crucial for the project viability. Solid particles materials to be implemented in concentrating solar power plants are thermal aged and thermal cycled in this study to evaluation of solid particles at high temperatures. A homemade device has been developed to perform accelerated-durability tests, that allows emulation of thermal cycling stress from days to years, and even evaluate the 11,000 cycles expected to be reached during 20 years' plant's lifetime in less than four months. A detailed description of the operation of this device is included in this paper. In addition, current solar absorptance, chemical composition, physical properties, thermal characteristics, and morphologic analysis of the samples before and after thermal treatments have been performed. The materials under the study are the most reliable solid particles reported in CSP field: silicon carbide (SiC) and CarboHSP® 30/60. Characterization results show that SiC is more affected on its durability by thermal cycling than by constant temperature aging treatment while CarboHSP® is affected by temperature aging rather than thermal cycling. SiC reacts with oxygen to form SiO2 on the surface, with a positive effect in its solar absorptance. Nevertheless, with thermal cycles, SiC particle surface becomes damaged and the reaction continues with more new exposed surface. Meanwhile, CarboHSP® reduces its solar absorptance with high temperature only due to changes in its surface chemical composition. However, thermal cycling shows no negative effect in CarboHSP® properties.

Harvested from ORCID Public Data FileCamila Barreneche in OpenAIREEnergy storage technologies can provide energy security, fight climate change, and improve the value of current or future energy systems. Thermal Energy Storage (TES) is a key enable technology, it allows to stock thermal energy that can be further used for heating and cooling applications and power generation. The methods and tools used to analyse all the literature about the evolution of TES systems research are described in this paper. Bibliometrics is the science that studies, in a statistical way, the written publications of a certain field of research, and it is considered one of the few interdisciplinary research fields that can be extended to almost all scientific areas. The bibliometric analysis of the database Web-of-science (core collection) shows highlighted information in order to figure out the scientific outputs. The importance of the bibliometrics is to analyse a knowledge development from a strategic point of view in order to detect its evolution regarding the research in such a field and to detect which are the opportunities within this area. This study presents the publication evolution in TES field over the last two decades, per year, per country, per authors, per journal, and per TES technology, taking into account sensible heat TES (SHTES), latent heat TES (LHTES), and thermochemical energy storage (TCS), and considering the connection between authorship communities and country interactions. The communities are obtained from the co/authorships, regardless of the country or affiliation; this permits to view the size of the communities, as well as to identify collaboration opportunities between communities with low or no interaction. Furthermore, studies are included regarding detailed analysis on each TES technology, as well as other factors (such as funding) that can influence the current and future research.

Harvested from ORCID Public Data FileMercè Segarra in OpenAIREThe use of paraffin, salts and salt hydrates as phase change materials (PCMs) have been researched extensively and used in a number of commercial applications. However, metals and metal alloys, which possess a high storage density on a volume basis as well as a substantially higher thermal conductivity, has received much less attention. This paper discusses the considerations for the use of metal and metal alloys as phase change materials for high temperature thermal storage applications, as well as summarises the literature on the limited research in this area. Although some pure metals and metal alloys present interesting thermal properties to be used as PCMs in thermal storage systems, there is a lack of understanding on the implications of the metallurgical aspects related to the melting and solidification of these materials under thermal cycling at high temperatures. The main issues to be considered include vapour pressure, undercooling, corrosion, segregation, changes in composition and microstructure, changes in thermal properties and undesired reactions. Further research is needed before these materials can be used as PCMs in thermal energy storage systems in industry. The research leading to these results has received funding from the European Commission Seventh Framework Programme (FP/2007-2013) under grant agreement n° PIRSES-GA-2013-610692 (INNOSTORAGE) and from the European Union's Horizon 2020 Research and Innovation Program under grant agreement No 657466 (INPATH-TES). The authors would like to thank the Catalan Government for the quality accreditation given to their research groups GREA (2014 SGR 123) and DIOPMA (2014 SGR 1543), and also the Spanish Government for the projects ENE2015-64117-C5-1-R and ENE2015-64117-C5-2-R (MINECO/FEDER, UE).

Harvested from ORCID Public Data FileMercè Segarra in OpenAIREAbstract The kinetics of conventional gold cyanidation in air has been studied using open circuit potential measurements, voltammetry and atomic absorption spectrophotometry. The experimental results show that this is a complex process characterized by the interdependency of the different variables (cyanide concentration, pH, temperature and stirring speed). The measurement of the mixed potentials at which the process takes place gives valuable information to ascertain the influence of each variable. A good correlation between mixed potential and dissolution rate, thus having a potential interest for an industrial application, has been found. The study of the current—potential curves for oxygen reduction on gold surface and anodic dissolution of gold in cyanide solutions gives more insight into the control of the process: depending on the experimental conditions, gold dissolution takes place in the active region (oxygen diffusion control) or in the potential region where dissolution of adsorbed species limits the rate of the process. Depending also on the experimental conditions, two or four electrons are transferred per oxygen molecule.

Depending also on the experimental conditions, two or four electrons are transferred per oxygen molecule.

Harvested from ORCID Public Data FileFrank Bruno in OpenAIREConsiderable effort has been devoted to the characterization of thermal properties of the different types of materials that can be used as thermal energy storage (TES) media, but scarce literature exists concerning the materials to manufacture the tanks that can be used to contain these storage media. One of the main concerns when selecting the most suitable material for these tanks is its resistance to corrosion due to molten salts that constitute the TES system. Dynamic gravimetric analysis is a newly proposed method for the study of corrosion on metals, which optimizes the standard procedure described by ASTM G1-03. The new technique avoids the direct handling of samples, so more accurate values can be obtained. In this work, the resistance to corrosion of AISI 316 stainless steel samples in contact with commercial grade molten salts of the Li2CO3-Na2CO3-K2CO3 system, at 600 °C for different exposure times, has been determined by using this new methodology. The results show that the initial corrosion rate is lower at higher amounts of lithium carbonate present in the molten salts mixture.

Harvested from ORCID Public Data FileLuisa F. Cabeza in OpenAIREAbstract Energy consumption for thermal comfort in buildings reached 20–40% of total energy consumption in the developed countries. This study evaluates the performance of a composite material with enhanced thermal inertia formulated with a solid waste to be used in buildings. The feasibility of incorporating electric arc furnace dust (EAFD) was evaluated. EAFD is a special waste used as filler in a polymer matrix. Paraffin wax is added with two functions: on one side as lubricant agent to promote a correct mixing between the inorganic filler and the polymeric matrix. Moreover, paraffin acts as phase change material (PCM) due to their high thermal energy storage (TES) capacity as latent heat from the phase change. In order to evaluate the performance as part of building systems of new material developed in this paper, several composite formulations were prepared and tensile strength test were performed, the thermal properties were analyzed by differential scanning calorimetry (DSC) and airborne noise acoustic properties were tested using an experimental cabin based on the UNE-EN-ISO140. The results were compared with a commercial material for acoustic insulation in constructive solutions. The material developed was a 3 mm dense sheet able to be used in combination with other materials as constructive systems.

Harvested from ORCID Public Data FileMiguel Morales in OpenAIREAbstract Fuel Cells (FCs) are electrochemical devices that directly convert the chemical energy of a reaction into electrical energy. The energy conversion processes theoretically remain unaltered as long as the fuel and oxidant feed the device. A single cell consists of two electrodes (anode and cathode), and an electrolyte, which can be a solid oxide that transports ions, thus becoming a SOFC (solid oxide fuel cell). To achieve the oxide-ion conductivity necessary to ensure high enough power density, these fuel cells require high and/or intermediate temperatures (over 500 °C).The fuel conversion efficiency of conventional SOFCs is usually about 50%. Thus, much of the chemical energy converts into waste heat energy, whereas thermoelectric materials can generate electricity from the waste heat. Some studies have been published in which the cathode of the fuel cell has been replaced by a thermoelectric material, and different simulation studies have been performed in which the waste heat is harnessed by thermoelectrics in a heat exchanger. The aim of this work is to provide an overview of thermoelectric materials that could help to select the best one to harness the heat evolved by a SOFC device to increase its efficiency. Data has been collected for different thermoelectric materials, including their thermoelectric performance, operation temperature range, and cost. To choose a thermoelectric material, it is necessary to define a performance parameter that allows us to classify all the different materials by means of their performance. Among the best, operating temperature and cost will turn into constraints that must be met to find the best material that suits the characteristics of a SOFC operation environment, and that really can be used in combination with the fuel cell.

Harvested from ORCID Public Data FileGeoffrey Will in OpenAIRE Ming Liu; Thermal energy storage (TES) is a critical component in a concentrated solar power (CSP) plant since it is able to provide dispatchability and increase the capacity factor of the plant. Recently the Brayton power cycle using supercritical carbon dioxide (s-CO2) has attracted considerable attention as it allows a higher thermal to electric power conversion efficiency compared to the conventional Rankine cycle using subcritical steam. However, no commercial TES has yet been developed for integration with a s-CO2 based plant. One reason is the lack of a suitable storage material. This work explores the use of a eutectic NaCl-Na2CO3 salt as a reliable high temperature phase change material (PCM). The PCM has been thermally cycled up to 1000 times. Its thermophysical properties have been measured before and after it has been subjected to the thermal cycling and its corrosion behavior has been investigated. This eutectic salt shows good thermal stability without degradation after cycling 1000 times between 600 and 650 °C. The corrosion rate on stainless steel 316 (SS316) increases linearly up to 350 cycles, and thereafter it stabilizes at 70 mg/cm2.
