Extracting battery metals from seafloor may beat traditional mining — study – by Cecilia Jamasmie (Mining.com – April 22, 2020)

Mining battery metals from the ocean floor could potentially eliminate or dramatically reduce most of the environmental and social impacts associated with the extraction of riches from the Earth’s surface, a new study claims.

According to a research published this week and funded by Canada’s DeepGreen Metals, a start-up planning to extract cobalt and other battery metals from the seabed, undersea mining generates up to 70% less direct CO2 emissions, 94% less stored carbon risk, as well as 90% less sulphur oxides (SOx) and nitrogen oxides (NOx) emissions — air pollution from maritime transportation.

Mining the ocean floor would also eliminate the issue of solid waste, while using 94% less land and 92% less forest, the report reads.

The study provides a broader context for a deeper, multi-year environmental and social impact assessment (ESIA) being conducted by DeepGreen.

The company says the study will be the largest integrated seabed-to-surface deep-ocean science program ever conducted, with over 100 separate studies being undertaken.
