Rare Earth Elements

What REE are, and why supply matters.

What are REE?

Rare earth elements include scandium, yttrium, and the lanthanides. They are used in magnets, wind turbines, EVs, electronics, optics, catalysts, and defence systems.

Current geopolitical situation

EU supply remains import-dependent and concentrated. Eurostat reported 12,900 tonnes of REE+ imports in 2024, with China the largest partner at 46.3% by weight.

History

Formed around 580 million years ago, the Fen Complex is the preserved root of an ancient volcanic system. The surface volcano has disappeared, but the deeper feeder system remains near Ulefoss and Lake Norsjø.

Geology

Fen is the global reference locality for carbonatites, unusual rock systems often associated with rare earth enrichment. This makes the area one of Europe’s most relevant geological settings for critical minerals exploration.

Today’s estimates

The wider Fen system is estimated at 15.9 Mt total rare earth oxides (TREO). The estimate includes neodymium and praseodymium, key rare earths used in permanent magnets for electric vehicles, wind turbines and advanced technologies.

Bærevann Context

The Bærevann report describes the area as a possible plan area for mass deposition and industry linked to underground extraction. It also records major nature values that would require further planning, avoidance, and mitigation.
