Manganese nodules found in the deep sea could provide critical metals needed for the energy transition with low CO2 emissions, as the demand for metals increases with the electrification of industrial processes, transport, and heat generation. Deep-sea mining of manganese nodules offers a more sustainable solution compared to land-based mining, which has negative environmental impacts. A new process developed by the Max Planck Institute for Sustainable Materials utilizes hydrogen for reduction, significantly reducing CO2 emissions compared to traditional methods. This innovative approach to sourcing critical metals could play a key role in advancing climate solutions and promoting a more sustainable energy transition.
