Siemens Gamesa celebrates the energy production of the first wind turbine equipped with its fully recyclable blades. This newly equipped turbine is part of RWE’s Kaskasi offshore wind project in Germany. In addition, the installation and commercialization of these blades marks a turning point in the sustainability of offshore wind.

Recyclable blades for the Kaskasi wind farm

Siemens Gamesa’s first turbine made of recyclable blades has started to produce energy. This first installation recently took place on RWE’s Kaskasi offshore wind project in Germany.

This wind project is located 35 km north of the island of Helgoland in the German North Sea. It consists of 38 DG 8.0-167 DD wind turbines and has a capacity of 342 MW. Thus, it should produce enough clean energy to power 400,000 homes, the equivalent of Frankfurt am Main.

In addition, Siemens Gamesa will equip a number of turbines in the Kaskasi park with B81 recyclable blades. These handmade blades are 81 meters long.

However, Siemens Gamesa also produces 108-meter (B108) and 115-meter (B115) long recyclable blades. These blades are used respectively on the SG 14-222 DD and SG 14-236 DD wind turbines.

In addition, they are composed of a combination of materials integrated in resin, forming a solid and rigid structure. This technology allows the complete recovery of the blade components at the end of its life.

In addition, after separation with a mild acid solution, the components are used for the development of new products. This creates a real potential for secondary markets and many jobs, especially at the local level.

Siemens Gamesa fights against the climate emergency

Marc Becker, CEO of Siemens Gamesa’s offshore business unit, emphasizes the importance of this innovation:

“We are proving that as leaders in the offshore revolution, we are committed to making disruptive technology innovation commercially viable at the pace that the climate emergency demands.”

The recyclable blades were put on the market in only 10 months. In fact, the company launched them in September 2021 and their installation on the Kaskasi project dates from July 2022. This underscores the pace at which businesses and solutions must evolve to address the global climate emergency.

Furthermore, with the recyclable blades, Siemens Gamesa hopes to create a virtuous circular economy. In fact, the company has set a goal of having only fully recyclable turbines by 2040.

As for Sven Utermöhlen, CEO of Wind Offshore at RWE, he explains:

“Testing the first recyclable wind turbine blades at our Kaskasi wind farm is an important step in taking wind turbine sustainability to the next level.”

Indeed, the expansion of renewable energies must be really pushed. In the offshore area in particular, faster expansion is important to achieve climate goals. Nevertheless, the aspect of energy sovereignty must also be a priority.
