OFFSHORE WIND – Denmark : recyclable blades for an offshore wind farm

The German energy company RWE announced on June 14 the installation of recyclable blades on the rotors of 40 of the 72 wind turbines (SG 14-236 DD) of the Thor park, located in the North Sea near the Danish coast. The company had already announced, last April, the installation of more ecological “GreenerTower” steel masts from Siemens Gamesa to equip this same park. The German company reiterates its confidence by equipping more than half of the wind turbines with recyclable blades from the same manufacturer. Thanks to a new type of resin, the composite materials of the blades can be separated at the end of their life and reused in other applications, the automotive industry for example. Offshore installation is scheduled for 2026 and the wind farm will enter production no later than the end of 2027. With a capacity of 1,000 MW, the wind farm will be able to produce enough electricity to supply the equivalent of more than one million households, or one in three Danish households. 

Wind power with vision: RWE to install recyclable rotor blades at Thor offshore wind farm to drive sustainability ; 

Sven Utermöhlen, CEO RWE Offshore Wind: “ At RWE we are fully committed to working towards circularity and net – zero emissions. We are already testing the world’s first recyclable wind turbine blades under real – life conditions at our German offshore wind farm Kaskasi and we have decided to install them at Sofia.

By using these rotor blades at our Thor offshore wind farm, too, RWE continues lead the way towards a circular offshore sector. And we are doing even more. We are the first developer in the world to pilot Siemens Gamesa’s CO2 reduced steel towers, which significantly reduce the carbon footprint of wind turbines. This is the right direction for the future of our sector, which has sustainability at its core.”

Maximilian Schnippering, Head of Sustainability at Siemens Gamesa: “More than one million tons of blade material are expected to be installed globally every year. Our recyclable blades can avoid those materials ending their life in a landfill and give them a second use.”
