Solar tower


Technology Description

Solar towers, also known as central receiver systems (CRS), use hundreds or thousands of small reflectors (called heliostats) to concentrate the sun's rays on a central receiver placed atop a fixed tower. The concentrating power of the tower concept achieves very high temperatures, thereby increasing the efficiency at which heat is converted into electricity and reducing the cost of thermal storage.

Relevance for Net Zero

High in regions with good Direct Normal Irradiation (DNI) resources, as solar thermal electricity (STE) plants in combination with thermal storage can provide electricity after sunset and support the integration of solar PV.
