Beyond Oil: The Rise of Critical Metals
Beyond Oil: The Rise of Critical Metals
Podcast Description
As oil fueled the 20th century, critical metals will drive the 21st century's electrification and clean energy revolution. The entire clean energy supply chain—from generation (wind, solar, nuclear) to transmission (copper) and storage (batteries)—requires massive amounts of critical metals. impossiblemetals.substack.com

Episode Description:
In this episode, Impossible Metals hosts a forward-looking conversation with Shane Tragathon, Head of Business Development and Partnerships at ReElement Technologies. Shane explains how ReElement’s breakthrough refining technology provides a modular, scalable, and environmentally friendly alternative to China’s solvent extraction dominance. He unpacks how chromatographic separation enables ultra-high purity outputs across rare earths, battery metals, and defense-critical elements — and how these systems can process ores, brines, recycled materials, and even seabed nodules.

Host:
Oliver Gunasekara – CEO & Co-Founder, Impossible Metals
Episode Timeline:
* Why refining is the real bottleneck in critical mineral supply chains (0:00 – 3:30)
* How ReElement’s chromatography-based technology works (3:30 – 7:15)
* Achieving 99.999% purity without toxic solvents or legacy inefficiencies (7:15 – 12:00)
* Flexible inputs: from recycled EV batteries to polymetallic nodules (12:00 – 16:40)
* Advantages of modular, deployable refining near ports and mining sites (16:40 – 21:10)
* The role of ReElement in U.S. national security and industrial resilience (21:10 – 25:30)
* Global partnerships in Africa, Europe, and with Impossible Metals (25:30 – 30:00)
* The future of distributed refining and its role in decarbonization (30:00 – 34:20)
Key Takeaways:
* Refining, not mining, is the chokepoint. China’s grip on mineral processing is the strategic bottleneck in supply chains, and ReElement’s approach directly addresses that weakness.
* Chromatography unlocks higher purity with lower impact. The system eliminates toxic solvents, recycles water, and slashes environmental risks while achieving up to 99.999% purity.
* Flexibility is a strategic advantage. Being able to process multiple feedstocks — from ores to brines to recycled batteries and nodules — makes the system resilient and future-proof.
* Modular refining strengthens supply chains. Deploying compact systems close to ports, mines, or recycling hubs reduces logistics costs, increases speed, and limits choke points.
* This is about security as much as sustainability. U.S. defense, aviation, energy, and tech sectors all rely on stable supplies of rare earths and battery metals — and distributed refining is key to resilience.
* Partnerships are accelerating deployment. From African battery hubs to European recycling and Impossible Metals’ seabed projects, ReElement is positioning globally.
