What happened
The United States is developing a technology to recover rare earth elements from coal ash, a waste byproduct of burning coal.
According to the announcement, the rare earth materials that could be extracted from these ash piles are valued at around $100 billion.
Why it matters
Global demand for rare earths is rising sharply as clean energy transition efforts and high-tech industries require more critical minerals.
Transforming coal waste into a source of these elements could address supply challenges without relying on conventional mining alone.
Key facts
The US is developing technology to extract rare earth elements from coal ash.
The recoverable rare earths are valued at approximately $100 billion.
Rare earth element demand is surging due to the clean energy transition and high-tech sectors.
What to watch next
Future updates will show whether this extraction technology can move from development to commercial-scale deployment.
Observers will be looking for cost comparisons between coal ash recovery and other rare earth production methods.
