Metal inputs from offshore wind farms could pose environmental, economic and human health risks
Large offshore wind turbines are made primarily of steel. When exposed to salt water, steel corrodes over time, leading to structural damage. To prevent this, offshore wind farm developers use corrosion protection systems. One of the most common methods involves attaching sacrificial anodes to the turbines. These metal blocks, mainly composed of aluminium, zinc and indium, dissolve into the seawater to protect the steel structure. The research team at the University of Portsmouth set out to quantify how much metal is being released from corrosion protection systems used in European offshore wind farms. Their findings suggest that the accumulation of these metals in the ocean could have long-term consequences for marine ecosystems, with particular concern over the potential to enter food chains.
