caption_attribution_description: English: The Hellisheiði Geothermal Power Plant is the site of the original CarbFix project, which injected approximately 200 tons of CO2 into the subsurface and fixed it as stable carbonate minerals.
context_page_description: Carbfix is a process that captures CO₂ and other acid gases in water, then injects this water into the subsurface where the gases are stored as stable minerals. Work developing this process began in 2007. Since 2020 Carbfix is a subsidiary of Reykjavik Energy.
  Carbfix was initiated jointly by the Icelandic President, Dr Ólafur Ragnar Grímsson, Einar Gunnlaugsson at Reykjavík Energy, Wallace S. Broecker at Columbia University, Eric H. Oelkers at CNRS Toulouse, and Sigurður Reynir Gíslason at University of Iceland to limit the Greenhouse gas emissions in Iceland. Reykjavik Energy supplied the initial funding for Carbfix. Further funding has been supplied by The European Commission and the Department of Energy of the United States. In addition to finding a new method for permanent carbon dioxide storage, another objective of the project was to train scientists for years of work to come.
  After years of preliminary experimental and field characterisation approximately 200 tons 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 tonnes of water per tonne of CO₂.

Research results published in 2016 showed that 95% of the injected CO₂ was solidified into calcite within 2 years, using 25 tonnes of water per tonne of CO₂. Since this time this successful carbon capture and storage approach has been upscaled at Hellisheiði and ongoing research is implementing this approach at other sites across Europe.
