Norwegian technology firm Sway Turbine has unveiled a unique, eye-catching 10 MW offshore wind turbine at the 3rd International Conference on Drivetrain Concepts for Wind Turbines in Bremen, Germany.
Called the ST10, the turbine features a large diameter, direct drive permanent magnet generator, which has an ironless stator core and a unique generator and blade rotor integration.
“This is a very exciting event for us, and we are very pleased to be able to reveal more details about this technology, which we believe represents a very cost competitive turbine alternative to the offshore wind market," said Ingelise Arntsen, Sway Turbine’s CEO.
"Obtaining a lower Cost of Energy is crucial for offshore wind to achieve the position this renewable energy source deserves in the total energy mix,” she said.
Throughout the development of the ST10, the firm's aim was to achieve a cost-effective low-weight design.
To reach this goal, the basic challenge of turbine up-scaling had to be overcome through several unusual design solutions.
The ST10 offers an estimated 15-20 percent reduction in turbine cost compared to current state of the art, conventional design offshore wind turbines, and a considerable reduction in cost per kWh produced on wind park level.
“As a technology development company, we are proud to present the ST10 design which has been developed by our engineers together with some of the most competent partners in the industry. We are now in the process of identifying the best industrial partner to bring this product to the market,” Arntsen said.
