Abstract

There is an expected increase in demand of critical raw materials, e.g. nickel and cobalt, mainly driven by the shift towards renewable energy solutions and the increase in production of electric vehicles. That trend has raised the interests for the mining of polymetallic nodules. The most extensive nodule depostions are found on the abyssal plains of the deep seas. In spite of their economic interest, concerns have been raised regarding the environmental impact of deep sea mining.
