“…This will increase the heat transfer rate, decrease the receiver temperature and thermal losses, and improve thermal efficiency, as discussed in the subsequent sections. 80,104 Flow inserts.-According to Table VIII, it was found that flow inserts can help to enhance the Nusselt number in the range of 50% to 742%. This indicates that the flow inserts can help to improve the heat transfer between the HTF and the receiver tube.…”

Recently, there has been a shift towards renewable energy sources for electricity generation due to rapidly depleting non-renewable energy sources. Solar energy is generally the most promising renewable energy source to be harvested by concentrated solar power (CSP) and solar photovoltaic (PV) technologies. CSP technology can be further classified into a few categories, such as parabolic trough collector (PTC), solar power tower, linear Fresnel reflector, and solar parabolic dish. In contrast, solar PV can be further developed into concentrated photovoltaic and concentrated photovoltaic thermal (CPVT) systems. The modifications (e.g. optical and thermal modifications) done on PTC and parabolic trough based CPVT systems on enhancing system performance are discussed. Next, the economic analyses conducted for both systems are discussed to compare the economic feasibility of the technologies employed in different countries. The appropriate recycling and CE approaches applied for PTC and PV technologies are reviewed and classified based on the key material elements within this industry. Overall, this paper compares PTC and parabolic trough-based CPVT systems from the technical, economic, and environmental aspects to provide insight for the solar energy harvesting field researchers.

“…The other common commercial HTF, molten salts, can theoretically withstand 600 • C, but there is a lot of literature showing that impurities seriously compromise this limit, since their decomposition starts at around 380-400 • C [25]. Therefore, future CSP plants are considering the use of air as a HTF [26]. (v) HTF thermal oil or molten salts in direct contact with concrete: migration of oil/salt in concrete.…”

Thermal energy storage (TES) allows the existing mismatch between supply and demand in energy systems to be overcome. Considering temperatures above 150 °C, there are major potential benefits for applications, such as process heat and electricity production, where TES coupled with concentrating solar power (CSP) plants can increase the penetration of renewable energies. To this end, this paper performs a critical analysis of the literature on the current and most promising concrete energy storage technologies, identifying five challenges that must be overcome for the successful exploitation of this technology. With these five challenges in mind, this paper proposes an approach that uses a new modular design of concrete-based TES. A preliminary study of the feasibility of the proposed system was performed using computational fluid dynamics (CFD) techniques, showing promising results.

“…The PTC is the most mature thermal concentrating solar power (CSP) technology (Bilal Awan et al, 2020; Fuqiang et al, 2017; Gharat et al, 2021, among others) including STE. As a basic common feature, in a PTC a cylindrical parabolic‐shaped reflector focuses the incoming direct component of the solar irradiance.…”

Parabolic trough collectors and linear Fresnel collectors are mature technologies for power production, and they are being recently applied to provide solar heat for industrial needs. Conventionally, they use a liquid as heat transfer fluid, either thermal oil or water, to carry heat from the receivers up to the point of conversion or delivery. Although liquids offer excellent thermal properties, they show technical limitations, besides environmental concerns, which have encouraged the research on alternative solutions. This work reviews the main research works on the use of gases as heat transfer fluid in linear concentrating collectors, including solar power and heat production, highlighting the potential applications and technical challenges. The review indicates: first, gases offer potential to replace liquids, and second, there is a need for more research and development to define the best technical compromises to reach practical application in every sector.
