Efficient energy systems
Action taken by company: 

Fossil fuels will remain the backbone of energy supplies for a long time. To use coal, oil and gas as efficiently as possible, Siemens is continually improving the efficiency of products, systems and plants. These innovations have been a decisive factor in making coal- and gas-fired power plants worldwide more eco-friendly.


With the biggest and most powerful gas turbine generation (8000H) Siemens achieved an efficiency rating of 60.75%in combined cycle operation, setting a world record in 2011. The Ulrich Hartmann Power Plant in Bavaria’s Irsching, the first to operate the 8000H turbine, is thus the world’s most efficient combined cycle power plant.


In making sure that it would meet all current and future requirements, more than 750 Siemens employees, including 250 engineers, were involved in the development of the new gas turbine and the new combined cycle plant. Over 10 years, Siemens invested more than €500 million in turbine development and in the construction and operation of the prototype plant. The plant became commercial in summer 2011. Shortly afterwards, first orders were received from Florida, USA, South Korea and lately from Dusseldorf, Germany.


The increased efficiency in the power plant results in a reduction of CO2 emissions by 43,000 tons a year, compared with modern power plants. Thus, it eliminates CO2 emissions equal to the amount emitted by 10,000 medium-sized cars driven 20,000 kilometres a year.



Through innovation and long term R&D a continuous improvement even of mature technologies is possible in terms of higher availability and reliability as well as higher efficiency, which meets climate requirements.
