Research shows up to 90% carbon footprint reduction for critical minerals for electric vehicle batteries when sourcing them from deep-sea polymetallic nodules compared to conventionally mined land ores
Polymetallic nodules from the Clarion Clipperton Zone (CCZ) of the Pacific Ocean contain rich concentrations of four metals required for EVs in a single ore, including nickel, a crucial ingredient in EV batteries, which will increasingly be mined from beneath large forested carbon sinks in tropical areas like Indonesia and the Philippines
As governments scramble to secure supplies of critical minerals to build renewable infrastructure, the paper analyzes the planetary-scale and full lifecycle
