Wind Turbines

In modern wind turbines, neodymium magnets are used in permanent magnet generators (PMG). They enable higher efficiency and lower energy losses compared to traditional generators. The magnets provide a stable magnetic field, allowing energy generation even at low wind speeds.

Electric Vehicles

Electric motors in electric vehicles (EV) use neodymium magnets to provide high torque and efficiency. Their compact size allows for the design of lighter and more efficient cars, increasing range and reducing energy consumption.

Solar Tracking Systems

In photovoltaic installations, neodymium magnets are used in precision motors that drive solar trackers. These systems rotate solar panels to follow the sun’s movement, increasing efficiency by 20-30% compared to fixed installations.

Challenges and Limitations

• Dependence on China: China controls 90% of neodymium magnet production, posing risks of supply disruptions, as seen with sanctions in 2025.

• Recycling: Used wind turbines and EV motors require efficient magnet recovery methods, which are costly and technologically challenging.

• Environmental Impact: The extraction of neodymium and other rare earth metals generates waste, raising concerns about sustainable development.

Prospects for Poland and the EU

Poland, as a producer of wind turbines and EV components, can benefit from the development of renewable technologies. However, diversifying magnet supplies and investing in recycling are necessary. The EU promotes projects like Horizon Europe, supporting the development of alternative materials and technologies.

Summary

Neodymium magnets are the foundation of renewable technologies, enabling efficient energy production and utilization. Their role in wind turbines, electric vehicles, and solar systems is invaluable. However, supply dependencies, recycling challenges, and environmental impacts require innovation. Poland and the EU have the opportunity to play a key role in the sustainable development of these technologies.
