The Way I Heard It with Mike Rowe 484: Tom Albanese—The Metals at the Bottom of the Ocean
14 snips
May 12, 2026 Tom Albanese, a mining executive who led Rio Tinto and Vedanta and now chairs American Ocean Minerals, talks about polymetallic nodules three miles under the Pacific. He explains why these potato-sized rocks matter for batteries, AI, and defense. The conversation covers nodule harvesting technology, environmental science on plumes and regeneration, and the geopolitical race for critical metals.

Episode notes
Polymetallic Nodules Are An Oceanic Battery Resource
- Polymetallic nodules are a massive, underutilized source of battery metals sitting on abyssal plains rather than embedded in rock.
- Tom Albanese describes golf-ball to softball sized nodules rich in nickel, cobalt, copper, manganese, titanium and rare earths scattered across huge seafloor areas.
Copper Demand Will Reach Historical Cumulative Levels
- Global copper demand will consume as much copper in the next 25 years as all prior human history.
- Albanese warns electrification, data centers and decarbonization drive unprecedented copper demand, pressuring existing terrestrial supply.
Nodule Sample Is A Layered Battery With Shark Teeth
- Tom demonstrates a nodules sample and calls it a 'battery in a rock' with layers like tree rings and sometimes shark teeth inside.
- He notes nodules contain around 30 elements and form over millions of years by ocean chemistry cycles.
