OverviewComparison between CSP and other electricity sourcesHistoryCurrent technologyCSP with thermal energy storageDeployment around the worldCostEfficiency

As a thermal energy generating power station, CSP has more in common with thermal power stations such as coal, gas, or geothermal. A CSP plant can incorporate thermal energy storage, which stores energy either in the form of sensible heat or as latent heat (for example, using molten salt), which enables these plants to continue supplying electricity whenever it is needed, day or night. This makes CSP a dispatchable form of solar. Dispatchable renewable energy is particularl

Thermal storage for concentrating solar power plants

Solar thermal power plants use the energy of the solar radiation to provide the heat needed to operate a thermal power cycle.
