Launch of world’s first recyclable wind turbine blade for commercial use offshore
Siemens Gamesa launches the RecyclableBlade, the world’s first wind turbine blade that can be recycled at the end of its lifecycle
Siemens Gamesa is leading the way for a sustainable future with the RecyclableBlade, the world’s first recyclable wind turbine blades ready for commercial use offshore. With this technology, separation of the materials in the blade is possible at the end of its lifetime, enabling recycling into new applications and thereby defines the next milestone in sustainability.
The first six 81-meter long RecyclableBlades have been produced at the Siemens Gamesa blade factory in Aalborg, Denmark.
Andreas Nauen, CEO of Siemens Gamesa, states:
“In pioneering wind circularity – where elements contribute to a circular economy of the wind industry – we have reached a major milestone in a society that puts care for the environment at its heart. The RecyclableBlade is another tangible example of how Siemens Gamesa is leading technological development in the wind industry.”
Many components of a wind turbine, such as the tower and nacelle components have established recycling practices. Until now, the composite materials used in wind turbine blades have been more challenging to recycle. Built on proven, reliable processes, the Siemens Gamesa RecyclableBlade breaks this mould and is the first of its kind, enabling recycling at the end of its lifecycle, and sets the path to a future where the full recyclability of projects will be a market requirement.
Siemens Gamesa is committed with RWE to install and monitor the world's first wind turbines with recyclable blades in Germany at the Kaskasi offshore wind power plant. Current plans are for the project to be producing energy from 2022 onwards.
Sven Utermöhlen, CEO Wind Offshore, RWE Renewables:
“We are pleased that our offshore wind farm Kaskasi is able to provide a fantastic facility for testing innovations; here we are preparing to test special steel collars and to use an improved installation method for foundations. Now, Kaskasi installs the world’s first recyclable wind turbine blade manufactured by Siemens Gamesa. This is a significant step in advancing the sustainability of wind turbines to the next level”.
Siemens Gamesa wind turbine blades are made from a combination of materials cast together with resin to form a strong and flexible lightweight structure. The chemical structure of this new resin type makes it possible to efficiently separate the resin from the other components at end of the blade’s working life. This mild process protects the properties of the materials in the blade, in contrast to other existing ways of recycling conventional wind turbine blades. The materials can then be reused in new applications after separation.
Siemens Gamesa offshore customers will now have the unique possibility to choose the RecyclableBlade as an option for their future projects.
Siemens Gamesa recently launched an ambitious Sustainability Vision towards 2040, pushing the boundaries of sustainability to create a better future for generations to come. Under this umbrella, the company announced an ambitious goal to make turbines fully recyclable by 2040.
Gregorio Acero, Head of Quality Management & Health, Safety, and Environment at Siemens Gamesa, said:
“Our aspiration is to produce wind turbines that can generate renewable electricity for 20-30 years. When they reach the end of their useful life, we can separate the materials and use them for new relevant applications. The RecyclableBlade is a great step in that direction and well ahead of our 2040 goal.”
