“…174 It is observed that increasing the plant size, the capital cost can be reduced significantly. 175 The specific cost for a PTC with 40 MW can be reduced by 28% at 160 MW, 176 and 12.1% by doubling the plant size of 50 MW. 175 Mokheimer et al 177 found that specific cost for a 10 MW PTC plant can be dropped by 61% at 160 MW, by 48% at 80 MW, by 37% at 40 MW, and by 19% at 20 MW.…”

Inexhaustible energy sources are the focus of the energy industry for meeting the increased need for energy and reducing carbon emissions. Among various alternatives, harnessing solar energy has become a promising choice around the world. Parabolic trough collectors (PTCs) are an effective way to transform radiant energy into thermal energy, as well as electricity. However, these collectors can be improved by refining their design and tweaking the parameters related to thermal behavior. This may be done either by enhancing the surface area or improving the heat transfer coefficient of the heat carrying medium. These kinds of improvements could be achieved by making the use of nanofluids and by using inserts or fins within the collector tube. The current study provides an extensive review of PTCs from the points of view of their design, along with their thermal characteristics. Different types of nanofluids as the working liquid are investigated and discussed to achieve better PTC performance. Inserts within the collector tube and various design approaches, including fins, twisted tubes, U-shaped tubes, coiled wire inserts, and porous twisted tape inserts, are reviewed and discussed in detail. Finally, based on this review, challenges of PTC applications are described and future research recommendations are proposed.

“…As previously mentioned, the parabolic shape of the mirror (approximated to a cylindrical shape in the domain of this application) will be slightly modified by the influence of gravity. The error can be calculated as (15) indicates. The maximum slope perturbation appears approximately at a distance L/4 from its center, which results in an error equal to 12/32 × G.…”

“…One of the negative features of concentrated solar power (CSP) is the huge amount of materials needed to build a solar thermal unit. For a 50-MWe facility with some storage capability, more than 70 km of trough collectors are needed, if this type of "concentrator" is used in the plant, embodying more than 5000 tons of glass, 7000 tons of steel, and 10,000 tons of concrete [15,16]. This is a clear hint in regard to the goal of reaching better CSP economics by making simpler units, which offer remarkable savings in material and significant reductions in complex embodiments [17].…”

“…This is likely the main route to a low cost. Note that a standard 50-MW solar plant with trough collectors and a small solar multiple [19] (about 1.1) has more than 5000 tons of steel, 4000 tons of glass, and 13,000 tons of concrete [15,16]. Some innovative proposals suggest using epoxy resins instead of steel and substituting aluminum foils for glass mirrors, although reflectivity is poorer in this case.…”

A New Thermal-Solar Field Configuration: The Rotatory Fresnel Collector or Sundial

2021

A new type of Fresnel array has been devised and constructed as an answer to the need to reduce the investment costs of solar thermal collectors, without jeopardizing their efficiency in capturing solar radiation at high temperatures. The array of mirror bands is fixed onto a horizontal platform, which rotates around a virtual vertical axis, so that the sun is in the extrapolated vertical plane of symmetry of the array. The receptor central line is also placed in said plane, and it is physically made of at least one tube at each side of the plane. The geometrical relation between the mirrors and the receptor is therefore fixed. The platform rotates with the same speed as that of the sunlight’s azimuthal component. On the contrary, the angle of incidence of the sunlight on the mirrors changes as the sun rises and declines in its daily apparent motion, but this effect does not disturb the radiation concentration kinematics, although it induces a shift along the receptor. This is a new configuration based on the use of simple and cheap flat mirrors to obtain circular cylindrical mirrors. These mirrors are made of originally flat mirrors that are bent by applying an inexpensive and simple bending technique patented by our research group. The radius of curvature of each mirror is tuned to the distance from the mirror to the receiver central line. The integration of different scientific domains (such as structural analysis) and elementary technologies (such as 3D printing) in this innovative solar radiation concentrator and receiver can lead to a large reduction in costs. Nevertheless, the first experimental campaign has shown additional problems in the receiver configuration, which should be addressed in a next stage of research. This paper explains the methodology used and procedures in the development of the first prototype of the Sundial.

Algeria’s energy demands are tremendously growing, and on the African continent it ranks among the countries with the highest energy consumption. To counter its growing energy demand, the country is progressively adopting renewable energy technologies, although conventional energy technologies still play a central role in its electricity production. The huge solar energy potential in Algeria can be exploited and utilized to meet the country’s growing energy demand with minimal greenhouse gas production. Given that concentrating solar power is viewed as one of the most promising alternatives in the field of solar energy utilization, this study investigates the viability of a 100 MW parabolic trough-based power plant at Tamanrasset, Algeria. The plant was simulated in the System Advisor Model software considering the actual electricity load profile of the targeted location and implementing two different condenser types: evaporative and air-cooled. By comparing the plant’s electricity production to the city’s real load, the plant was in position of supplying about 78% and 60% of the city’s electricity demand during the winter and summer seasons, respectively. The results show that implementation of such CSP plants could play an important role in meeting the energy demand as well as mitigating climate change through greenhouse emissions avoided in electricity generation process.
