Could Sucking Up the Seafloor Solve Battery Shortage? The Metals Company wants to try, but opposition is fierce – by Prachi Patel (IEEE Spectrum – September 13, 2021)

Reeling from a crushing shortage of semiconductor chips for vehicles, carmakers also face another looming crisis: producing enough batteries to drive the global pivot towards electric vehicles.

The supply of metals like cobalt, copper, lithium, and nickel needed for batteries is already shaky, and soaring demand for the hundreds of millions of batteries in the coming decades is likely to trigger shortage and high prices.

Some companies want to harvest metallic treasures from the sea. Strewn across large swaths of ocean plains some 5,000 meters deep are potato-like lumps called polymetallic nodules rich in metals and rare-earth elements critical for batteries and electronics. Nodules in the Clarion-Clipperton Zone (CCZ), which stretches between Mexico and Hawaii, are estimated to contain more cobalt and nickel than there are in deposits on land.

The Metals Company (previously DeepGreen Metals) in Vancouver expects to be the first to commercially produce metals from these nodules by 2024. And CEO Gerard Barron is confident they can do this without harming critical subsea ecosystems.
