Hence, the electricity generation by solar thermal technologies involves the collection and concentration of solar radiation in the form of heat and its conversion into electricity. The limitation of solar power generation technologies is the diurnal (day and night) and intermittent (hourly, daily, and seasonal) nature of solar radiation.
Harnessing solar energy for electric power generation is one of the growing technologies which provide a sustainable solution to the severe environmental issues such as climate change, global warming, and pollution. This chapter deals with the solar thermal power generation based on the line and point focussing solar concentrators.
To compare the different solar thermal power generation systems, some key characteristics/parameters are important to analyze the performance of the power generation system. Some of those parameters are discussed as follows: Aperture is the plane of entrance for the solar radiation incident on the concentrator.
Solar thermal power plants are primarily built in desert-like areas that are not suitable for agri-cultural use due to lack of water. Land consumption is therefore not an obstacle. The specific land requirement for a solar thermal power plant is around 1.3 hectares per gigawatt-hour of electricity per year (Ong 2013).
Together with industrial partners, we transfer innovations from the laboratory to large-scale applications. New heat transfer and storage media can withstand temperatures of 600 °C, higher than has previously been possible in solar thermal power plants. This increases the efi-ciency of converting solar radiation into heat and then into electricity.
Since solar thermal power plants can feed their electricity into the power grid even after sunset, they are of particular value for an energy system based on renewable energy sources. Solar thermal power plants are of strategic importance in sunny countries to be able to phase out coal and gas power plants in the future.
Technology Fundamentals: Solar thermal power plants
Volker Quaschning describes the basics of the most important types of solar thermal power plants. Most techniques for generating electricity from heat need high temperatures to achieve reasonable efficiencies. The output temperatures of non-concentrating solar collectors are limited to temperatures below 200°C.

Supercritical Carbon Dioxide Solar Thermal Power Generation
The key advantage of solar thermal power generation technology when compared with PV technology is the lower cost of thermal storage compared with battery storage. In trough plants, the mineral oil can be used for sensible thermal storage. Solar salt, a 60–40% mixture of sodium and potassium nitrate, has been used for central receiver plants.

Solar thermal power plant
Solar thermal power plants are electricity generation plants that utilize energy from the Sun to heat a fluid to a high temperature. This fluid then transfers its heat to water, which then becomes superheated steam. This steam is then used to turn turbines in a power plant, and this mechanical energy is converted into electricity by a generator.
