About this episode
The episode discusses the critical minerals challenge in clean energy, focusing on the refining process rather than mining.
Rare earths are having a moment. And if you work anywhere near clean energy, batteries, EVs, data centers, defense, or domestic manufacturing, this conversation should be on your radar. And, when it comes to rare earths (aka critical minerals), it seems everyone talks about mining. But according to Mark LaVerghetta, that's not where the real critical minerals challenge lies. Nico got a chance to sit down with Mark, co-founder of ReElement Technologies, in person finally, and learned that the true bottleneck in the clean energy transition is refining . You can dig rare earth elements out of the ground, but they still need to be separated, purified, and transformed into the high-purity materials used in batteries, EVs, defense systems, data centers, and advanced electronics. Today, much of that refining capacity remains concentrated overseas (yes, largely China), creating vulnerabilities that extend far beyond clean energy. As AI accelerates demand for advanced materials and geopolitical tensions reshape global trade, domestic refining has become a matter of economic resilience and national security. Mark explains why ReElement is pursuing an "innovation, not imitation" approach to…
