Critical Minerals

Critical minerals sit at the center of nearly every clean energy transition story worth telling. Lithium, cobalt, rare earth elements, copper, and dozens of other materials form the physical backbone of batteries, motors, solar panels, and grid infrastructure. Without reliable, responsible access to these resources, the math on decarbonization simply does not work.

On The Grove, Earth Onward returns to this topic because it surfaces in almost every corner of climate tech. Founders building in energy storage, industrial decarbonization, and advanced manufacturing all eventually face the same upstream question: where do the materials come from, and what does it cost to get them cleanly and at scale?

The throughline across these episodes is the gap between what the energy transition demands and what current supply chains can actually deliver. Guests like Gaurav and Anat Tewari of Tewari De-Ox Systems bring the conversation down to earth, showing how process-level innovation in extraction and refining can move the needle on both economics and environmental impact.

If you are exploring this hub, you will come away with a clearer sense of where real technical progress is happening, what the remaining bottlenecks look like, and which founders are building serious companies around the problem. These are not abstract policy conversations. They are practitioner accounts from people working inside one of the harder material challenges of the century.
