The EU aims to reduce dependency on imports of raw materials. Large quantities of raw materials can be found in deep sea Polymetallic Nodules. Polymetallic Nodules contain relatively high concentrations of Nickel, Copper and Cobalt. Cobalt is especially valuable to harvest since it is used in batteries for electric cars. Nodules occur at any depth, but the highest abundance has been found between 4,000 and 6,000m. How do you harvest these nodules at such a large depth?DeRegt was asked to join an EU funded consortium of 14 companies. Industry, research institutes and service companies across seven different countries joined hands to solve the question on how to harvest them, avoiding serious harm and minimizing the environmental risks.
