Resumen

[0000] A solar power tower system includes a solar tower receiver, a cold storage tank and a hot storage tank at the bottom of the tower receiver with a heat transfer fluid down pipe from the receiver and a working fluid up pipe into the receiver. A potential energy recovery system is located at the bottom of the tower configured such that it recovers part of the mechanical energy of the heat transfer fluid and uses it in the pumping of the working fluid to the receiver and providing power to other equipment in the solar power tower system in any kind of energy.
