Siemens Presents New Energy Efficient Technologies

At the World Energy Congress, September 12 to 16, 2010, in Montreal, Canada, the world's energy leaders have been gathering to present new concepts and promising solutions for our planet's future energy supply. This year's theme is: "Responding now to global challenges - Energy in transition for a living planet."

According to Wolfgang Dehen, CEO of Siemens' Energy Sector and member of the company's Managing Board, "... the 20th century was distinguished by meeting growing energy demand, and thus rapid consumption of fossil fuels, [but ] now ... we face the question of how we can put our energy system on a sustainable foundation given continued expansion in energy demand but declining fossil fuel resources and climate change."

"An integrated energy system is needed worldwide," he asserts, "to help ... make electricity the most important source of energy. Besides its versatile usage, electricity allows the extensive integration of a variety of renewable energy sources and highly efficient bulk power transport over huge distances."

At the congress, Siemens offered a variety of new technologies to help optimize the energy mix towards greener energy generation. For example, Siemens is supplying wind turbines with a combined capacity of 227 megawatts (MW) for a wind farm located in Oklahoma, North America, and recently signed a framework agreement with Samsung C&T Corporation to supply wind turbines in Ontario, Canada, with a combined capacity of up to 600 MW (enough for 240,000 Canadian households).

Siemens has also pioneered  a new generation of energy-efficient gas turbines, which cut fossil fuel consumption in combined-cycle power plants by a third.

Siemens will supply two of these high-efficiency gas turbine packages for a coal-fired integrated gasification combined-cycle (IGCC) power plant in Liberty, Mississippi. Approximately 65 percent of CO2 emissions from this power plant are expected to be captured and recycled - a reduction of three million tons of CO2 per year.
