Advances in Floating Platforms To Take Wind Farms Off Coasts
Advances in floating platforms could take wind farms far from coasts, reducing costs and skirting controversy.
Offshore wind-farm developers would love to build in deep water more than 32 kilometers from shore, where stronger and steadier winds prevail and complaints about marred scenery are less likely. But building foundations to support wind turbines in water deeper than 20 meters is prohibitively expensive. Now, technology developers are stepping up work in floating turbines to make such farms feasible.
Several companies are on their way to demonstrating systems by borrowing heavily from oil and gas offshore platform technology. If these efforts succeed, they could open up a resource of immense scale. For example, according to a 2006 analysis by the U.S. Department of Energy, General Electric, and the Massachusetts Technology Collaborative, offshore wind resources on the Atlantic and Pacific coasts exceed the current electricity generation of the entire U.S. power industry.
