Solid particle thermal energy storage design for a fluidized-bed concentrating solar power plant

A fluidized-bed concentrating solar power plant comprising:

• a particle receiver configured to contain solid state particles, wherein the particle receiver heats the solid state particles by transferring thermal energy from sunlight to the solid state particles;
• a first silo configured to receive and store heated solid state particles from the particle receiver;
• a heat exchanger configured to receive the heated solid state particles from the first silo and generate a fluidized mixture comprising the heated solid state particles suspended in a gas;
• a second silo configured to feed cooled solid state particles to the particle receiver, the cooled solid state particle extracted from the fluidized mixture;
• wherein the first silo and the second silo each comprise:
• a foundation comprising a base supported by a plurality of micropile units, wherein each micropile unit comprises a plurality of micropile columns coupled to a support block, wherein the base is supported by the support block of each of the plurality of micropile units and each of the plurality of micropile columns extending into the ground under the foundation.
