How does temperature affect solar power block performance?
Regarding the power block, it is common knowledge that the cycle performance is directly affected by the maximum cycle temperature, improving as that temperature increases. Nevertheless, the solar field efficiency is lower as the working temperature increases, as the heat loss also increases.
What are the efficiencies of a solar-to-electricity power plant (STPP)?
In this type of STPPs, solar-to-electricity efficiencies are around 25%, since the power block is limited and its thermal performance is in a range between 35% and 38% and the solar field efficiency is around 65%.
How to choose a solar thermal power plant?
Solar thermal power plants for electricity production include, at least, two main systems: the solar field and the power block. Regarding this last one, the particular thermodynamic cycle layout and the working fluid employed, have a decisive influence in the plant performance. In turn, this selection depends on the solar technology employed.
What are the benefits of concentrating solar power (CSP)?
Benefits Uniquely Valuable to CSP Reduces capital costs by increasing the efficiency of converting sunlight into energy. Research Focus Areas (also see References) Supercritical carbon dioxide (sCO2) power cycles have the potential to reduce the cost of concentrating solar power (CSP).
What is a concentrating solar system (STPP)?
A STPP includes, at least, two main systems: the solar field and the power block. There are basically four concentrating solar technologies that can be coupled to a power cycle: linear Fresnel collector (LFC), parabolic trough collector (PTC), central receiver (CR) systems, and parabolic dish (PD) (Zarza-Moya, ).
Does the tsrc-sco2 cycle generate less work per unit of solar heat?
This implies that the TSRC-sCO2 cycle generates less work per unit of solar heat than the conventional cycle. Therefore, the benefit of providing electricity storage services and being able to take advantage of price fluctuations should be considered. Economic results are also presented in Table 3.
