Abstract

A solar energy power plant is provided with a steam cycle for providing steam for driving a turbine, a thermal absorption cycle with a working fluid for absorbing solar energy and at least one heat exchanger for transferring absorbed solar energy to water of the steam cycle. The working fluid is supercritical water. The steam cycle and the thermal absorbing cycle are working with water, but they are separated from each other.
