RWE Proves Even Giant Turbines Can Be Reborn

RWE deploys the first offshore turbine featuring CO₂-reduced steel and recyclable blades at the massive 1.1 GW Thor project in Denmark

22 Apr 2026

RWE has completed the installation of a wind turbine designed for circularity at the Thor offshore wind farm in Denmark. The unit is the first of its kind to integrate a steel tower produced with lower carbon emissions alongside rotor blades that can be fully recycled at the end of their operational life.

The development addresses long-standing concerns regarding the environmental impact of decommissioned turbine components. Standard rotor blades are typically made of composite materials that are difficult to break down, often resulting in disposal in landfills. The new blades use a specialized resin that allows materials to be separated and reused in the automotive and consumer goods industries.

Sven Utermöhlen, chief executive of RWE Offshore Wind, said the company is taking a significant step toward a fully circular offshore wind economy. He noted that the integration of these materials reduces the carbon footprint of the turbine by roughly 20 per cent.

The 1.1 gigawatt Thor project is currently the largest offshore wind development in Denmark. Once complete, it will comprise 72 turbines, with half of the towers constructed from steel produced in renewable-powered furnaces using scrap metal. This manufacturing process results in 63 per cent fewer emissions than traditional methods.

The Danish project began delivering its first power to the national grid earlier this year. RWE expects to complete the installation of all units by the end of 2026. Of these, 40 turbines will be equipped with recyclable blade technology.

European regulators are increasingly focusing on the lifecycle of renewable energy infrastructure. As governments tighten environmental standards, the adoption of circular manufacturing processes is expected to become a standard requirement for offshore tenders. The successful deployment of these technologies at scale suggests that the supply chain is beginning to adapt to these shifting regulatory expectations.
