A new study published in Environment Research Letters, led by Katarzyna Kowalczyk of the Potsdam Institute for Climate Impact Research (PIK), explores a promising carbon dioxide removal (CDR) strategy: Ocean Alkalinity Enhancement (OAE), specifically through ‘ocean liming.’ This method, using hydrated lime, shows significant potential for contributing to the Paris climate target, with costs ranging from $130 to $295 per ton of CO2 removed.
The study calls for expanded research into ecosystem impacts and policy frameworks, suggesting ocean liming could play a crucial role in our CDR portfolio. Dive deeper into the findings and explore how we can harness the ocean’s power in the fight against climate change.
