Knowledge summary, A deep-sea experiment on carbon dioxide storage in oceanic crust
On Iceland, water enriched with carbon dioxide has been injected into the upper ocean crust since 2014 – and successfully. The carbon dioxide mineralises within a short time and is firmly bound for millions of years. However, since ocean crust only rises above sea level in a few places on Earth, res...
