SHCC – Entwicklung eines neuen Konzeptes für Solar-Hybrid-Kraftwerke

In the medium term Solar Hybrid Combined Cycle (SHCC ® ) power plants are expected to play an important role in power generation since they are able to supply the electricity market its requirements while utilising existing limited and high grade natural resources economically. SHCC ® powerplants are characterised by the integration of high temperature solar heat into the gas turbine process and in addition - depending on the scheme of the process cycle - downstream into the steam cycle. The input of the solar heat is a done between compressor outlet and combustor inlet of the gas turbine either by direct solar thermal heating inside the receivers of the solar tower or by indirect heating via interconnection of a heat transfer medium. In addition high efficiency of a hybrid power plant process based both on high temperature solar heat and fossil fuel, the concept has considerable advantages in the permanent availability of the power plant output by the combination of both energy sources. Thus, the SHCC ® concept requires no additional standby capacity. The development of the SHCC ® concept is funded by the Federal Ministry for Environment, Nature Conservation and Nuclear Safety of the Federal Republic of Germany.
