Concentrating Solar Thermal Power (CSP)

By April 1, 2022No Comments

Also called concentrating solar power or solar thermal electricity, STE. Technology which uses mirrors to focus sunlight into an intense solar beam that heats a working fluid in a solar receiver, which then drives a turbine or heat engine/generator to produce electricity. The mirrors can be arranged in a variety of ways, but they all deliver the solar beam to the receiver. There are four types of commercial CSP systems: parabolic troughs, linear Fresnel, power towers and dish/engines. The first two technologies are line-focus systems, capable of concentrating the sun’s energy to produce temperatures of 400 °C, while the latter two are point-focus systems which can produce temperatures of 800 °C or higher .
