Today we review research conducted in Iceland into a technique that converts atmospheric CO2 into a carbonate solid for storage underground rather than the better known CCS approach which attempts to store CO2 underground in its gaseous state, with all of the risks of it leaking back into the atmosphere later. Preliminary testing and drilling near Reykjavik indicate that up to 5,000 tonnes of CO2/year can be stored this way. The feasibility for this to significantly address global emissions will be tested when this technique is scaled up to much larger rates.
