Gunnarsson, I.; Aradóttir, E.; Oelkers, E.; Clark, D.; Arnarson, M.; Sigfússon, B. et al. (2018): The rapid and cost-effective capture and subsurface mineral storage of carbon and sulfur at the CarbFix2 site. In: International Journal of Greenhouse Gas Control 79, S. 117–126. DOI: 10.1016/j.ijggc.2018.08.014.

„Here we present a novel integrated carbon capture and storage technology, installed at the CarbFix2 storage site at Hellisheiði, Iceland that lowers considerably the cost and energy required at this site. The CarbFix2 site, located in deeper and hotter rocks than the original CarbFix site, permits the continuous injection of larger quantities of CO₂ and H₂S than the original site. The integrated process consists of soluble gas mixture capture in water followed by the direct injection of the resulting CO₂-H₂S-charged water into basaltic rock, where much of the dissolved carbon and sulfur are mineralized within months.“
