An Innovative Hybrid Solar Gas-Turbine Power Plant based on the TopCycle Concept

• The TopCycle is an innovative gas-turbine power plant, in which a supercharger unit is added to a conventional industrial gas-turbine to boost the pressure ratio, and large amounts of steam are injected into the combustion chamber in order to achieve near- stoichiometric combustion. A thermoeconomic simulation model of a hybrid solar version of such a power plant has been developed, allowing determination of its thermodynamic and economic performance, and the results are compared with a more conventional hybrid solar combined cycle power plant. The analysis has shown that a hybrid solar TopCycle power plant can produce electricity with CO2 emissions below 300 kgCO2/MWhe at levelized costs around 60 – 80 €/MWhe, lower than the competing hybrid combined cycle units, and directly competitive with wind power.
