Siemens' New SGT5-8000H Gas Turbine Recipient of Innovation Award

Posted on July 7, 2009

The Siemens Energy Sector received the special award for “Climate protection with steel” at the German Steel Innovation Awards for its new SGT5-8000H gas turbine. The machine is deployed as a prime mover in combined cycle power plants. In combination with a steam turbine it will attain a world-record efficiency of over 60 percent. High efficiency levels are essential for saving fuels and thus conserving natural resources, and for significantly reducing CO2 emissions to protect the climate

Combined cycle power plants currently attain efficiencies of over 58 percent. An increase in efficiency of two percent points translates into annual CO2 savings totaling approximately 40,000 metric tons. That is equivalent to the CO2 emissions of approximately 10,000 mid-range automobiles clocking up 20,000 kilometers a year. Siemens invested approximately US$700 million in development of the new turbine, construction of the gas turbine plant in Irsching and subsequent trial operation.

Approximately 95 percent of the new Siemens gas turbine weighing a total of 444 metric tons is made of steel. In spite of this these machines are not “heavy metal“ but special “high tech“ products, in which steel contributes toward climate and environmental protection. The new gas turbine is a unique combination of classic heavy mechanical engineering and ultramodern manufacturing technology.

The new Siemens H Class gas turbine has an output of approximately 340 megawatts (MW) in simple cycle operation. That is sufficient to provide electricity for the entire population of a city the size of Hamburg. In combined cycle duty the output will be approximately 530 MW, which would be enough to supply the city of Berlin with its more than 3 million inhabitants with eco-friendly electricity. The turbine was produced at the gas turbine manafacturing plant in Berlin, which has since 1972 delivered over 600 gas turbines for deloyment in power plants to customers in more than 60 countries around the globe.
