First offshore wind turbine to be buoyed off Norway
Wind power's best days may be out at sea.
Energy company StatoilHydro on Thursday announced , a project to test a large-scale offshore wind turbine.
The 2.3-megawatt turbine, a Siemens machine that is 65 meters high, will sit atop a buoy tied down by three anchors.
The system can work in depths ranging from 120 meters to 700 meters, according to StatoilHydro. It will be tested, starting in 2009, off the coast of Norway.
But there are a number of technical challenges and the cost burden of building electricity transmission lines back to where it can be used.
So there is still a lot of research and development required before offshore turbines are deployed for commercial power generation.
"The wind turbines must work satisfactorily even when subjected to movements, and it must also be possible to carry out necessary maintenance to the highest of safety standards," said Alexandra Bech Gjørv, the head of new energy at StatoilHydro, in a statement.
