Using alkaline rock minerals to combat climate change

Press release on geomar.de

How can carbon dioxide (CO2) be removed from the atmosphere and stored safely and permanently in the ocean? This question is being investigated by scientists from seven nations led by GEOMAR Helmholtz Centre for Ocean Research Kiel in an experiment just starting in the Raunefjord near Bergen, Norway. In mesocosms, free-floating, experimental enclosures, they are exploring whether the ocean can absorb additional CO2 from the atmosphere through the addition of alkaline minerals – known as ocean alkalinisation – and what influence this has on marine communities. The study will last until mid-July and takes place as part of the Ocean-based Negative Emission Technologies (OceanNETs) project funded by the European Union.
