The first V236-15.0 MW prototype is expected to be installed in 2022, while serial production is scheduled for 2024.
One challenge is to make the blades recyclable, and Vestas is also part of a major consortium developing sustainable techniques for recycling wind turbine blades.
The three year DecomBlades project was launched in Denmark last week and includes Ørsted, LM Wind Power (part of GE Renewable Energy),Siemens Gamesa Renewable Energy, FLSmidth, MAKEEN Power, HJHansen Recycling, Energy Cluster Denmark (ECD), University of Southern Denmark (SDU) and Technical University of Denmark (DTU).
Today 85 to 95 percent of a wind turbine can be recycled, but cost-efficient recycling of composite materials used for the turbines remains a challenge. On a global scale, an estimated 2.5 million tons of composite materials are currently in use in wind turbines.
The wind power industry produces far less composite waste compared to other industries – such as the construction, electronic, transport and shipping industries – nonetheless it is an important objective for the wind power industry to ensure sustainable recycling solutions exist for all materials used in a wind turbine. As the wind power industry grows, that responsibility becomes even bigger.
In DecomBlades, the ten project partners will investigate and develop solutions to recycle the composite material in wind turbine blades. The project focuses on three specific processes: shredding of wind turbine blades such that the material can be reused in different products and processes; use of shredded blade material in cement production; and, finally, a method to separate the composite material under high temperatures, also known as pyrolysis.
