Study: EU offshore wind expansion faces pressure from rare earth demand
Understand this event
On October 10, Tech Xplore reported that a study published in Nature Energy found that if the EU prioritizes offshore wind expansion, rare earth demand could still approach the level in a full expansion scenario, even if solar and onshore wind construction slows. The model estimates that by 2050, total installed wind and solar capacity in the offshore wind priority scenario would be about 22% lower, but the rare earths required for new equipment would still total about 69,200 tonnes, or 93% of the full expansion scenario. The estimate assumes that material requirements per unit of installed capacity remain unchanged. It covers only new power generation equipment added relative to 2023, excludes materials needed for grids, energy storage, and electric vehicles, and does not represent annual demand.

⚪ Background
What happened
A report dated October 10 describes a study in 《Nature Energy》 that modeled wind and solar expansion across the 27 EU countries through 2050: in the offshore-wind-priority scenario, total installed capacity is about 22% lower than in the full-expansion scenario, while rare earth demand for new equipment remains about 69,200 tonnes, equivalent to 93% of the latter. This is cumulative demand for new equipment relative to 2023, not annual demand; the model assumes material use per unit of capacity remains unchanged and excludes the grid, energy storage, and electric vehicles.

Involves:offshore wind turbines、Permanent magnet、rare earths
Seller impact
- ScenarioAt the macro level, under the model’s assumptions, a smaller scale of expansion does not necessarily mean a proportional drop in rare earth demand: offshore turbines use more rare earths per unit of capacity, and the technology mix constrains long-term demand. This result does not prove that rare earth prices will rise in the near term. [1]
- InferenceAt the micro level, the report cites China’s share of magnetic rare earth refining output in 2024 at 91%, suggesting that refining and magnet production remain bottlenecks. If supply is constrained, related procurement costs and deliveries may come under pressure; pricing power, cost shares, lead times, and substitution certifications are unknown, so recheck supplier quotes over the next two weeks. [1]
Suggested action
When procuring offshore wind turbines or permanent magnets, verify the sources of refining and magnet production, current quotes, and lead times with existing suppliers.
Evidence that would disprove the assessment
- Assessment 1：If an updated model using verified low-rare-earth technologies shows a substantial decline in demand under the offshore-priority scenario, this assessment should be revised.
- Assessment 2：If suppliers confirm that substitute magnets are certified and readily available, and that both quotes and lead times are stable, then the inference of near-term pressure does not hold.
