“Wind energy is expanding rapidly across the United States and now is the time to be planning for the complete life cycle of wind turbine materials,” said Jeff Marootian, principal deputy assistant secretary for the Office of Energy Efficiency and Renewable Energy at DOE. “The winners of this prize, and their innovative recycling technologies, prove that we can decommission turbines in a manner that is sustainable, economical, and advances our vision for building a comprehensive domestic recycling ecosystem.”
In January of this year, 20 teams were selected as winners of the first phase of the prize, Initiate!, and awarded $75,000 each for their innovative wind material recycling concepts that focused on economic and environmental sustainability. These teams have since been competing in the final Accelerate! phase, where they’ve worked to further develop their concepts, perform prototype demonstrations of their technologies, and submit a plan to demonstrate the technology at full scale.
As wind energy deployment in the United States continues to accelerate, enhancing recycling has been a key piece of DOE’s ongoing efforts to create a circular economy for wind energy. A critical component of this work is addressing the 10%–15% of a wind turbine’s mass that cannot currently be commercially recycled. This prize incentivized the development of novel recycling solutions for these difficult-to-recycle materials—such as carbon fiber or fiberglass composites and rare earth elements—and supports the commercialization of these technologies to help grow the U.S. wind energy industry.
The Accelerate! phase submissions showcased the wide range of technology that can contribute to a sustainable wind energy ecosystem in the United States, from solutions for recovering rare earth elements from used wind turbine magnets to technologies that transform the fiber-reinforced composites in turbine blades into usable materials for other applications. The six winning teams, who hail from five states, demonstrated that their prototypes have exceptional potential as full-scale technologies that will enhance the wind recycling industry.
The Accelerate! phase winners are:
Cimentaire (Houston, Texas)
Critical Materials Recycling (Boone, Iowa)
Fletcher Team (Huntington, West Virginia)
GreenTex Solutions, LLC (Charleston, South Carolina)
United Standard Materials Corporation (Houston, Texas)
WIND REWIND (Orono, Maine).
The winning teams can use their $500,000 cash award and technical support vouchers to advance their prototypes toward relevant scale demonstration and validation. While Accelerate! is the final competition phase of the Wind Turbine Materials Recycling Prize, a Pitch Day event is planned for 2025, at which participants will have the opportunity to present work completed since the close of the prize and demonstrate the commercial potential of their technologies.
