“…Particle Receiver ▪ Design and testing of configurations to reduce radiative and thermal losses, especially at high temperatures (>700 reviewed as one of the promising energy conversion systems for the next-generation CSP plants [98] alongside the financial support that has been made available internationally to aid technological advancement. Compared to the conventional modern steam power cycle in CSP plants, with a thermal to electrical energy efficiency of ~44 %, recent studies have concluded that sCO 2 Brayton power cycle thermal to electrical energy efficiency higher than 50 % coupled to solar central receiver technologies [44,94,[99][100][101]. Greater thermal efficiency of the power cycle is key to lowering LCoE of CSP plants.…”

Concentrated solar thermal (CST) systems are pivotal in the pursuit of renewable energy solutions to meet emissions reduction targets. They play a vital role in addressing the negative impacts of energy-intensive industrial processes, such as the high-temperature calcination step in the alumina Bayer process, requiring temperatures of approximately 1000 °C. However, achieving such high temperatures poses challenges, as radiative losses increase significantly with temperature. Current commercially available CST technologies, employing heat transfer mediums like molten salts, are constrained to temperatures below 600 °C. The emerging focus on sand-like ceramic particles, either as standalone materials or in suspension within an air stream, as heat transfer mediums signifies a promising avenue in the development of high-temperature receiver-based CST technologies. These particle-laden suspension flow receiver systems have the potential to reach operating temperatures exceeding 1000 °C. This review paper provides a comprehensive overview of CST technologies, with a primary focus on high-temperature particle receivers. It sheds light on the existing challenges within the CST state-of-the-art technologies and introduces the concept of refractory-lined particle receivers. This paper also underscores the significance of transient-based thermal analysis for high-temperature particle receivers and highlights the necessity of such analyses to guide their practical implementation. By addressing these critical aspects, this review paper contributes to the advancement of CST technologies, emphasizing their role in achieving sustainable, high-temperature heat for emission reduction objectives.

The energy consumption has gradually increased in the current context. Fossil fuels are the primary source of energy for the world’s population. Furthermore, energy derived from fossil fuels has significant disadvantages, including increased pollution and global warming. Solar energy is the fastest-growing alternative to fossil fuels among the various energy options. As a result, the focus of the present work is on the thermo-economic analysis of a hybrid solar-assisted intercooled gas turbine (GT) and organic Rankine cycle (ORC) for waste heat recovery and power production at near-zero-emissions. The work outcome and maximum efficiency of the hybrid arrangement are 1342.12 kW and 71.12% respectively at the cycle pressure ratio of 8, and 443 K entry point turbine temperature. The economic model of the integrated system depicts that the unit power production cost for the combined system has been evaluated as 1932 e per kW.
