Geothermal power plant technology

Siemens uses an advanced, optimized form of Kalina technology for geothermal power plants. Unlike conventional power plants, which use water as the working medium, SiGeo uses a mixture of ammonia and water. This mixture vaporizes at considerably lower temperatures than water and provides the most efficient means of transferring heat compared with other working media.

Siemens optimizes the power plant for your requirements (see graphic).

We take into account your requirements for tapping process heat and district heating as well as all possible cooling options, such as wet, dry, hybrid, and direct cooling, depending on local factors. Connection to the existing power supply system, including adapting the voltage levels if necessary, rounds out our range of services.   We pay particular attention to selecting the right material for the heat exchangers to ensure that it is suitable for the thermal water that you’ll be using. The modern equipment in our Erlangen materials test laboratory enables us to select the optimum material for the heat exchangers through comprehensive testing and research.

This scientific approach allows us to offer you an unlimited guarantee on this critical component.
