Wind farms are expanding around the world. This is good for climate change. Wind turbines are being installed on the high seas with nacelle heights of more than 100 meters and rotor diameters of nearly 170 meters. This increases both the electricity yield and economic efficiency. Freudenberg is aiding wind power’s conquest with high performance components and materials.
The name has a military overtone, but it is the future of wind power: In the middle of the Baltic Sea between Germany, Denmark and Sweden, the “Kriegers Flak” wind farm is rising from the sea to over an area of 132 square kilometers. At dizzying heights of more than 100 meters, massive towers bear nacelles and 80-meter blades, giving the wind turbines a total height of almost 200 meters - by comparison the Cologne Cathedral is only 157 meters high. The latest generation of turbines to be built in Kriegers Flak are among the most powerful in the world; each individual turbine can generate up to eight megawatts of electricity. And with good reason. The more powerful turbines require smaller foundations, fewer towers and fewer cables relative to the energy yield – and can thus be run more efficiently. More and more turbines can now operate without any government support. Wind power is thus being established as an independent, climate friendly energy form.
