Over 15 miles from the coast of Scotland, a wind power project could foreshadow a major part of our clean-energy future. Hywind Scotland, situated in Buchan Deep, is the world’s first floating wind farm, with its five six-megawatt turbines now generating electricity. On shore, a one-megawatt-hour lithium battery also helps smooth its potentially erratic supply of electricity to the grid.
The project, which is a collaboration between the Norwegian oil firm Statoil and Masdar Abu Dhabi Future Energy, makes use of turbine towers that are 253 meters tall, with 78 meters of that submerged in the North Sea. Each tower is tethered using three cables that are anchored to the seabed.
