“…It is worth observing that the above assessment was made assuming typical CSP plants with "medium size" heat storage capacity, i.e., in the range of 6-8 h [5,60]. However, CSP plants with larger TES size (up to 16 h or more) are expected to be developed in the future due to the increasing importance of "dispatchability" in the management of power grids with increasing penetration of vRES (variable Renewable Energy Sources) and technologies such as PV and wind [64].…”

“…Considering a 50 MWe CSP plant with overall reflective area of the solar field of 735,750 m 2 , 2.0 solar multiple and 35.6% Power Block efficiency [60], the average solar heat collected by the HTF will be QHTF = 2.0 * (50 MWe)/0.356 = 280.9 MWth; this thermal output (QHTF) results from the difference between the effective solar radiation on solar receivers (Qrec) minus the overall heat losses in the solar field (Qloss):…”

Different fluid compositions have been considered as heat transfer fluids (HTF) for concentrating solar power (CSP) applications. In linear focusing CSP systems synthetic oils are prevalently employed; more recently, the use of molten salt mixtures in linear focusing CSP systems has been proposed too. This paper presents a comparative assessment of thermal oils and five four nitrate/nitrite mixtures, among the ones mostly employed or proposed so far for CSP applications. The typical medium-size CSP plant (50 MWe) operating with synthetic oil as HTF and the “solar salt” as TES was considered as a benchmark. In the first part of the paper, physical properties and operation ranges of different HTFs are reviewed; corrosion and environmental issues are highlighted too. Besides an extensive review of HTFs based on data available from the open literature, the authors report their own obtained experimental data needed to thoroughly compare different solutions. In the second part of the paper, the impact of the different HTF options on the design and operation of CSP plants are analyzed from techno-economic perspectives.

“…[19] revealed that the photovoltaic (PV)-wind hybrid system is more cost-effective than the PV or wind system alone. Aseri et al [20] also evaluated the techno economics, possibilities, and capital investment cost for the parabolic trough collector (PTC) and STPP models in India. Their study revealed that solar tower power plants (STPP) are able to deliver higher annual electricity and reduce LCOE.…”

India is endowed with a lot of solar radiation as a result of its location. The Indian government therefore intends to maximize the usage of its solar energy resources through the development of solar power plants across the country. The concentrated solar power plant (CSP) is one of the technologies that rely on solar energy for its electricity generation. The type of condenser model in the CSP technology has the potential to affect its techno-economic viability. In this paper, a 100 MW solar tower power plant (STPP) with two different condenser models, i.e., the dry-cooled STPP and wet-cooled STPP models, are studied using the System Advisor Model (SAM) at six different geographical areas in India. The study employed the optimization of the thermal energy storage and the solar field size to identify the minimum levelized cost of electricity (LCOE) for all six locations. Results from the simulation show that the LCOE will range between 13 and 17 cents/kWh under the optimization conditions for the STPP dry-cooled condenser model, while that of the wet-cooled condenser model will range between 12.40 and 12.96 USD cents/kWh for the study locations. It was also observed that the optimized solar multiple (SM) for the dry-cooled STPP model ranges between 1.4 and 1.8, whereas that of the wet-cooled model ranges between 1 and 1.8. The study identified Bhopal as the best location for installing the STPP plant for both condenser models. In addition, this paper also discusses major potential barriers and government policies that are needed to develop CSP technologies in India. The outcome of the study is expected to help both government and other stakeholders in decision making and policy formulation for the sector.

“…During the operation of the CSP plants, the heliostats concentrate the solar energy on the heat receiver. The molten salt in the receiver is heated by solar energy and then guided to the molten salt heat storage device or power circulation device 7 . The storage tank is an integral part of the thermal energy storage system (TESS) in the CSP plant.…”

“…The molten salt in the receiver is heated by solar energy and then guided to the molten salt heat storage device or power circulation device. 7 The storage tank is an integral part of the thermal energy storage system (TESS) in the CSP plant. The unreasonable design of the storage tank may make the molten salt cool to the freezing point, which seriously threatens the safe operation of the power plant.…”

The leakage of molten salt storage tanks in concentrating solar power plants has attracted much attention. This paper focused on seepage and migration characteristics of molten salt in the thermal‐steady foundation fillers with different configurations after leakage occurs through a self‐built experimental system modeling the actual leaking process. The results show that the thermal insulation of light expanded clay aggregate (LECA) as foundation fillers is better than that of sand and gravel. When the operating temperature is 565°C, the average temperatures of each layer of LECA, sand, and gravel are 131.73°C, 141.91°C, and 149.27°C, respectively. And the seepage depths in light expanded clay aggregate, sand, and gravel are 482 mm, 223 mm, and 270 mm, respectively. It is found that the seepage depth of molten salt distinctly increases with higher operating temperature in all kinds of fillers. Nevertheless, the seepage depth of molten salt in the multi‐layer fillers diminishes with the increase of the thickness of the sand or gravel layer. The results obtained from this research would be helpful for the engineering design of storage tank foundations and reduce economic losses and the complexity of accident handling.
