Abstract
A concentrating solar power plant includes a solar light capturing part configured to capture solar light; and a heat exchange part configured to transform solar energy, from the captured solar light, into heat, which is stored in a solid medium, wherein the solid medium is stored underground. The solar light capturing part has a heliostat farm, a beam down solar concentrator, and a compound concentrator, each configured to reflect the solar light.
Claims20
A concentrating solar power plant comprising:
- a solar light capturing part configured to capture solar light;
- and
- a heat exchange part configured to transform solar energy, from the captured solar light, into heat, which is stored in a solid medium, wherein the solid medium is stored underground,
- wherein the solar light capturing part has a heliostat farm, a beam down solar concentrator, and a compound concentrator, each configured to reflect the solar light so that reflected light from the compound concentrator is directed to the solid medium to directly interact with the solid medium.
A concentrating solar power plant comprising:
- a solar light capturing part configured to capture solar light;
- and
- a heat exchange part configured to transform solar energy, from the captured solar light, into heat, which is stored in a solid medium, wherein the solid medium is stored underground,
- wherein the heat exchange part includes a solid medium bowl that receives the solid medium and the solar light simultaneously, so that the heat from the solar light is directly transferred to the solid medium, and
- wherein the heat exchange part further includes an underground storage tank configured to store the heated solid medium.
A method for generating electrical energy from solar power, the method comprising:
- capturing solar light with a solar light capturing part;
- heating a solid medium with the solar light reflected by a solar light capturing part, wherein the solid medium is stored underground, in a storage tank of a heat exchange part, and the solar light capturing part incudes a heliostat farm, a beam down solar concentrator, and a compound concentrator, each configured to reflect the solar light so that reflected light from the compound concentrator is directed to the solid medium to directly interact with the solid medium;
- spreading the heat uniformly in the solid medium by moving the solid medium from a bottom of the storage tank to a top of the storage tank with a conveyor system;
- transferring the heat from the solid medium to a liquid that flows through a coil located in the storage tank;
- boiling water in a boiler, based on the heated liquid;
- and
- generating the electrical energy with a turbine based on steam obtained by boiling the water.
