Seattle, United States [RenewableEnergyWorld.com] Principle Power Inc. has been awarded a U.S. Department of Energy grant to support the development of advanced water power technologies. The scope of work for the US $750,000 grant will be finalized in the coming months with government coordinators. Proceeds are to be used for the design, validation and levelized cost analysis of an innovative floating support structure for wind and wave energy power take-off mechanisms.
Project partners include the U.S. National Renewable Energy Lab (NREL) and Marine Innovation and Technology (MI&T). A support structure for large offshore wind turbines, called the WindFloat, will be adapted to accommodate wave energy generation.
Conceived by MI&T and owned by Principle Power, the WindFloat is a patent pending floating support structure for offshore wind turbines with a simple and elegant design. Features of the WindFloat dampen wave and turbine induced motion, enabling wind turbines to be sited in previously inaccessible locations where water depth exceeds 50 meters and wind resources are superior.
