“…By looking at the four configurations selected by the algorithm, it is possible to notice that there are optimal values for both bracket thickness and height, which are 3 mm and 200 mm, respectively. Instead, the minimum plate thickness allowable is found to be 3 mm and in correspondence with the maximum number of brackets welded on the plate (9). Therefore, the second configuration of Table 3 can be the final choice for the design of the secondary mirrors since it minimises the plate thickness among the four possible configurations and it guarantees the same thickness for the brackets and the plate itself, helping the welding process.…”

“…The literature focused on plant layout and receiver dimension optimisation by minimising the LCOE or maximising the efficiency of the plants [13,14]. Other works focused on fluidisation technologies [15] or materials for fluidised beds [9,16] for beamdown CSP plants. Studies on CSP plants' exergy analysis are present [2,5], highlighting that heliostats and central receivers are the major sources of exergy loss.…”

“…Beam-down installations have been realised in Japan, Israel, United Arab Emirates, China, and Italy [8]. The beam-down optical experiment [9,10] (BDOE) at the Khalifa University's Masdar Institute Solar Platform (Abu Dhabi, UAE) and Magaldi STEM ® [11], developed by Magaldi Power (Italy), are recent examples of CSP plants implemented with beam-down concentrators.…”

Concentrated Solar Power (CSP) plants use mirrors to reflect and concentrate sunlight onto a receiver, to heat a fluid and store thermal energy, at high temperature and energy density, to produce dispatchable heat and/or electricity. The secondary mirror is a critical component in the optical system of certain Solar Power Tower plants (SPT), as it redirects the concentrated sunlight from the primary mirror onto the receiver, which can be arranged at ground level. In this study, we propose a design optimisation for the secondary mirror of a CSP plant. The design optimisation method consists of two steps. The first step involves the use of the finite element simulation software Abaqus 2022 to analyse the structural performance of the secondary mirror under thermal loads and wind. The second step consists of the use of simulation results to identify the combination of design parameters and best performances, with respect to both design constraints and structural safety. This is carried out by developing an algorithm that selects those configurations which satisfy the constraints by using safety coefficients. The proposed optimisation method is applied to the design of a potential configuration of a secondary mirror for the beam-down of the CSP Magaldi STEM® technology, although the methodology can be extended to other components of CSP plants, such as primary mirrors and receivers, to further enhance the structural performance of these systems.

“…A molten salt mixture consisting of 60% by weight of sodium nitrate (NaNO3) and 40% by weight of potassium nitrate (KNO3), also known as solar salt or nitrate salt [2] - [6], [9], [10], [12], [14] - [17] has emerged as a practical and proven choice especially for solar thermal energy storage systems. Solar salt boasts a low cost and excellent thermal performance, making it an attractive option for thermal applications that use both direct and indirect storage systems, with particular attention to CSP and PV technologies.…”

This research paper thoroughly examines the fundamental principles and design concepts of molten salt thermal energy storage systems, focusing on the critical role of materials selection in choosing the appropriate material for the application. We also discuss the basic design components of these systems when integrated with renewable technology and classify practical systems by their applications. Based on our analysis, we conclude that solar technologies with molten salt storage systems are particularly promising for practical implementation, and the two-reservoir type system utilizing the sensible heat storage method of molten salt is regarded as the most commercially viable and mature electrothermal storage system available. Solar salt is also considered the best choice for these systems due to its low cost and high energy density. The idea of retrofitting fossil fuel plants with molten salt storage systems is also mentioned. Overall, molten salt thermal energy storage systems have the potential to play a crucial role in future energy systems, and further research and development in this field is essential for maximizing the potential of these systems and achieving a sustainable energy future.
