DOE Selects Viryd for Wind Study

Viryd Technologies Inc. has been selected to participate in a U.S Department of Energy (DOE) funded wind energy industry research consortium lead by the Illinois Institute of Technology (IIT). U.S. Energy Secretary Steven Chu announced the recipients last week as part of DOE’s efforts to spur university-led wind research facilities. Viryd was one of three wind turbine companies named as consortium members out of a pool of 100 applicants.

“Viryd’s advanced and efficient drivetrain technology delivers on the promise of small wind, and will help solidify the United States as an industry leader in wind turbine development,” said John Langdon, Viryd’s CEO. “We’re excited for the opportunity to demonstrate our technology on the national stage and are looking forward to working with IIT and DOE to foster development and enable small-scale wind to become a major contributor to the country’s renewable energy mix.”

Currently, testing is underway at the National Renewable Energy Laboratory (NREL) on its Viryd 8000 8-kilowatt turbine, which features NuVinci continuously variable planetary technology (CVP) licensed from Fallbrook Technologies Inc. The NuVinci CVP uses a set of rotating and tilting balls positioned between the input and output components of a transmission. Tilting the balls changes their contact diameters and varies the speed ratio.

As part of the IIT-led consortium’s research, one Viryd 8000 turbine will be installed on campus and another delivered to IIT’s engineering laboratories, where it will undergo reliability testing to monitor performance at different wind speeds and with varying degrees of wind turbulence. The consortium’s research will focus on several key issues facing the wind industry, including advanced concepts for rotor and drivetrain control.
