Key points
- DeepGreen describes partnering with ocean scientists to baseline the marine environment from seafloor to surface and study the impact of collecting polymetallic rocks.
- The rocks contain concentrations of cobalt, nickel, copper and manganese, the base metals used in batteries.
- The company says using these metals to make a billion electric car batteries could dramatically reduce environmental and social impact compared to land mining.
- DeepGreen frames its approach as a model where metals are rented and returned rather than mined and dumped.
