Denmark’s largest offshore wind farm, known as Thor, says it has installed the world’s first turbine with CO2-reduced steel towers and recyclable rotor blades, according to project operator, RWE.
The German-based energy group says it is the first company worldwide to use Siemens Gamesa’s GreenerTower. The tower plates are made from steel with at least 63% lower CO2 emissions than conventional steel by using renewable-powered furnaces and scrap steel, Kallanish understands.
In addition, the Thor windfarm will feature Siemens Gamesa’s recyclable rotor blades. Due to an innovative resin, the composite materials in these blades can be separated and reused, for instance in new casting applications in the automotive or consumer goods industries. RWE explains.
The Thor offshore wind farm off Denmark’s west coast will be laid out for a capacity of 1.1 gigawatts. In total, 72 wind turbines, each with a capacity of up to 15 megawatts, will be installed by the end of 2026. Half of them will be equipped with steel towers produced with a lower carbon footprint, and 40 turbines will feature a total of 120 recyclable rotor blades.
When fully operational in 2027, Thor will be capable of producing enough green electricity to supply the equivalent of more than one million Danish households. Thor offshore wind farm is a joint project between RWE (51%) and Norges Bank Investment Management (49%). RWE is in charge of construction and operations throughout Thor’s lifecycle.
