By technical reasons (limitation of the height of the tower to about 100 m because of the lack of availability of suitable systems to convey very high flowrates of hot particles up to the solar receiver beyond that height) and optimization of the solar receiver efficiency by using cavities that reduce the impact of high radiation thermal losses, the thermal power demanded
One form of electricity generation which is able to meet both of these requirements is concentrating solar power (CSP). CSP technologies are among the most viable and promising renewable energy technologies that can be scaled up for a rapid transition towards high renewable energy utilization scenarios [2], [3], [4].

Solar power towers generate electric power from sunlight by focusing concentrated solar radiation on a tower-mounted heat exchanger (receiver). The system uses hundreds to thousands of sun-tracking mirrors called heliostats to reflect the incident sunlight onto the receiver. These plants are best suited for utility-scale applications in the 30 to 400 MW e range. In a molten-salt solar

Emerging Technologies for Reduced Carbon Footprint. Bruce G. Miller, in Clean Coal Engineering Technology (Second Edition), 2017 Solar power tower. In the solar power tower concept, a field of tracking heliostats reflect solar energy onto a single receiver at the top of the tower (Ugolini et al., 2009; Sheu et al., 2012; Kuravi et al., 2013).The heat transfer media include steam/water,
Solar receivers, integral to solar power tower (SPT) plants, are responsible for capturing solar energy reflected by heliostats [1]. The efficacy of receiver surface coatings directly impacts energy absorption and radiation losses, thus crucially influencing thermal efficiency. Over time, the operation of receivers leads to a gradual decline in the optical performance of the coatings.

Requirements to a solar receiver include high thermal conductivity, dark color of the body for high absorptivity, and temperature resistance. Four concepts for receivers are described in this section.
The receiver has a height of 30.5 m and 14 panels (seven per flow path), each made up of 66 identical tubes. The receiver diameter is 15.8 m [ 8 ], hence with an AR of 1.93 and a lateral area of around 1500 m 2. The HTF is solar salt (40 % KNO3–60 % NaNO3, mol.%) operating between 290 °C and 565 °C [ 8 ].
These figures do not include effects of volume production or scaling of the power size of the plants beyond 50 MW unit size, which would result in further cost reductions [ 92 ]. Solar tower power plants need to be built in areas of high direct solar radiation, which generally translates into arid, desert areas where water is a scarce resource.
Improved operating procedures will be developed to provide more reliable operation and to raise the capacity factor of a solar tower plant. Use of efficient Rankine cycles and construction of new steam generator, which are developed specifically for solar application, enable the rising of the efficiency of a CRS.
Thus, it is possible that dry cooling technology of the power block will be a necessity for power towers to become a major provider of solar electricity in the future. In these fields, in the future, the demand for investments and research activities will rise for many companies.
Thus, solar thermal power stations can also be used for grid stabilization and a need-based power production. The parabolic trough, the solar dish, the Fresnel collector, and the solar tower belong to the group of solar thermal power systems. Parabolic trough and the solar tower are already competitive and economically feasible.
