Carbfix

Carbfix is an Icelandic company that has developed an approach to capturing and storing CO2 in water, and its injection into subsurface basalts. Once in the subsurface, the injected CO2 reacts with the host rock forming stable carbonate minerals, thus providing storage of the captured gas. Approximately 200 tons of CO2 were injected into subsurface basalts in 2012. Research results published in 2016 showed that 95% of the injected CO2 was solidified into calcite within 2 years, using 25 tons of water per tonne of CO2. Since this time this approach has been upscaled at Hellisheiði and ongoing research is implementing this approach at other sites across Europe. Background Carbfix was founded by the then Icelandic President, Dr Ólafur Ragnar Grímsson, Einar Gunnlaugsson at Reykjavík Energy, Wallace S. Broecker at Columbia University, Eric H. Oelkers at CNRS Toulouse (France...
