Gerard Barron, chief executive of The Metals Company, is positioning his firm to become the first in the world to carry out commercial-scale mining on the ocean floor. In a recent interview, Barron made his case for the controversial practice, arguing that extracting metals from the deep sea leaves a much smaller environmental footprint than digging them out of the ground on land.
The Metals Company is pursuing polymetallic nodules—potato-sized rocks rich in nickel, cobalt, copper, and manganese—found scattered across the seabed in international waters. These metals are considered essential for manufacturing electric-vehicle batteries and other clean-energy technology, fueling growing global demand.
Barron’s comparison highlights a broader tension in the push toward a low-carbon economy: sourcing the raw materials needed for renewable energy and electric vehicles often requires mining, whether on land or at sea, and each option carries its own ecological trade-offs. Traditional terrestrial mining can involve deforestation, toxic runoff, and disruption of local communities, while deep-sea mining raises concerns among scientists about damaging fragile, largely unstudied marine ecosystems that could take decades or longer to recover.
As regulators and environmental groups continue to debate the risks, Barron’s company is pushing forward, betting that the deep ocean could become a major new frontier for the metals powering the clean-energy transition.
