“…In another study, it was reported that concrete is a superior material for TES application because of better thermal and mechanical properties over a long period of time. Initial experiments at lab scale and in prototype showed good results, and the material was to be tested in actual field experiments at the Masdar Institute Solar Platform (MISP) in the United Arab Emirates [41]. Recently, dune sand had been investigated as a sensible energy storage system.…”

Solar energy is the most viable and abundant renewable energy source. Its intermittent nature and mismatch between source availability and energy demand, however, are critical issues in its deployment and market penetrability. This problem can be addressed by storing surplus energy during peak sun hours to be used during nighttime for continuous electricity production in concentrated solar power (CSP) plants. This article reviews the thermal energy storage (TES) for CSPs and focuses on detailing the latest advancement in materials for TES systems and advanced thermal fluids for high energy conversion efficiency. Problems of TES systems, such as high temperature corrosion with their proposed solutions, as well as successful implementations are reported. The article also reviews the economic analysis on CSP plants with TES systems and life-cycle assessment to quantify the environmental impacts of different TES systems.

“…Un enfoque de diseño para el intercambiador de calor entre el hormigón y el FTC es tener tuberías a través del bloque de hormigón, por medio de estas fluye el FTC. Uno de los problemas a considerar es que, a alta temperatura, se producen grietas después de ciclos repetidos de expansión y contracción térmica [22], [23].…”

Context: The energy and environmental panorama that our societies confront nowadays, demand for renew-able, clean and abundant sources of energy, not reliant on fossil fuels and detached from the geopolitical pressures the latter represent. In this scenario solar thermal energy arises as a viable and functional option. The main disadvantage of this emerging source of energy lies in the intermittent availability of solar radiation. Because of this difficulty, efficient processes for the storage of thermal solar energy becomes a highly relevant area of research. The aim of this paper is to present a survey on this topic.Method: A bibliographic review was carried out using the Scopus catalog. The search criteria for this purpose was defined using the following terms: solar+thermal+energy+storage+materials. This search pattern was applied to the title, abstracts and keywords of the contributions. Using the bibliometric tools of the citation database, the most cited documents were selected and the survey was developed.Results: A growing interest in the scientific community regarding this energy practice is evident starting from 2010. Characteristics, advances and trends in systems that use thermal energy storage materials are presented for sensible and latent heat, materials compound changeover phase, and finally thermo-chemical thermal storage materials.Conclusions: Improving the thermal conductivity of thermal storage materials is an important trend in current re-search. On the other hand, profitable practices for micro-encapsulated phase change materials and composite materials are analyzed. The optimization of thermo-physical properties as the melting point of thermal storage materials is explored with techniques such as eutectic mixtures and hydro-carbon chain length. Although the thermochemical materials are still in laboratory stage, they have a great potential as thermal storage materials in the future, given their large energy storage capacity per unit volume.

“…There is no available solution for TES at higher temperatures yet. Current research is focused on the development of refractory concretes and ceramics as new TES materials (Fernandez et al, 2010;Fernández and Grageda, 2015;Gil et al, 2010;John et al, 2013;Kuravi et al, 2013;Martins et al, 2015). However, these materials still need improvements mostly concerning their low thermal conductivity, their difficulty for shaping, or their high cost.…”

“…When they are used as TES material, nitrate salts of high quality are recommended to avoid corrosion of tank and other equipment, which usually increases cost of CSP plant (Kuravi et al, 2013). Thus, numerous works have recently been devoted to the improvement of Solar Salt or the development of new materials for sensible heat energy storage (Fernandez et al, 2010;Fernández and Grageda, 2015;Gil et al, 2010;John et al, 2013;Kuravi et al, 2013;Martins et al, 2015).…”

Alkali polyphosphates as new potential materials for thermal energy storage

et al. 2017

Until now, molten salts (nitrate-based salts) are the main materials for sensible heat storage at industrial scale. The working temperature range of these materials is limited below 500°C. There is not yet a solution for sensible heat storage at high temperature. This paper aimed to investigate alkali polyphosphates ((MPO 3) n , with M = Li, Na or K) as new promising materials for sensible heat storage at high temperature. Alkali polyphosphates could be formed by dehydration of monoalkali dihydrogenphosphates (MH 2 PO 4 , with M = Li, Na or K), which occurs below 400°C. Alkali polyphosphates resulted from this dehydration melted at 628, 657 and 812°C for sodium, lithium and potassium polyphosphate, respectively. All these liquids evaporated above 900°C but no destruction of their chemical structure was recorded. Sodium polyphosphate seemed to be the most promising material for sensible heat storage at high temperature because of its large potential working temperature (628-900°C), its availability and its low cost compared to lithium and potassium polyphosphates. The results open new prospects for the development of the thermal energy storage field.
