University of Edinburgh Study Demonstrates Permanent CO2 Storage in Icelandic Volcanic Rocks
Research from the University of Edinburgh shows that CO2 injected into volcanic rocks in Iceland can be permanently stored as solid minerals. By using natural chemical 'fingerprints,' the study reduces the need for artificial tracers, simplifying the monitoring process for carbon capture and storage (CCS) projects.
The research was conducted at Carbfix's storage site, where CO2 was dissolved in water, injected into basalt rock, and observed for reactions forming carbonate minerals. The findings align with previous mineralisation data and highlight the potential for reliable, low-cost monitoring methods essential for public trust and regulatory approval in CCS projects. The study indicates that volcanic formations in the UK could store over 3,000 million tonnes of industrial CO2 waste.
