ROTOR BLADES: WHY REPURPOSING THEM?
Wind power is one of the leading drivers of energy system transformation. However, within the coming years, the economic life cycle of a significant number of first-generation wind turbines is coming to an end. Nowadays there are hardly any established recycling and repurpose concepts for used rotor blades. Such high-quality material offers interesting possibilities for new fields of application. Fiberglass is both stiff and strong in tension and compression and is therefore capable of substituting other materials in innovative solutions. This substitution of otherwise needed materials has a positive effect on the environmental balance of the rotor blade and thus makes wind energy more sustainable. Since only a few people considered reusing rotor blades, the developed solutions will be innovative and unprecedented solutions.
The Answers You Need
HOW HEAVY AND LONG IS AN AVERAGE ROTOR BLADE?
The blade weighs about 10 tons when complete and is 45 m long. Each megawatt more needs about 10 tons more rotor blade weight.
WHAT IS THE AVERAGE SERVICE LIFE OF A ROTOR BLADE?
Normally 18 to 20 years.
