Climeworks Plant Construction

New Climeworks plant will capture 4000 tons of CO₂ per year. Mannvit is working on behalf of Climeworks on the construction of their direct air capture of CO₂ plant called Orca in the geothermal park in Hellisheidi, Iceland, just outside Reykjavik. The plant will be the largest CO2 plant in the world and is expected to be in operation this spring. The energy required to run the direct air capture process comes from purely renewable resources and is supplied by ON Power, operating the Hellisheidi Geothermal Power Plant. Learn more about the Orca plant on Climeworks' website.  

Carbfix will then handle the sequestration of the CO₂ into stone deep underground. Carbfix, carbon storage pioneers, and ON Power and Icelandic geothermal energy provider, will work together that will significantly scale-up carbon removal and storage in Iceland. Carbfix ensures the safe storage of the CO₂ through underground mineralization. The underground basaltic rock formations in Iceland provide the ideal conditions for this process, providing a permanent solution for CO₂ storage. 

Mannvit was also the main consultant to Carbfix during the development of the Carbfix CO₂ storage process, dating back to 2007. The CarbFix and SulFix projects are part of the NCG (non-condensable gas) treatment plant at Hellisheidi Geothermal power plant. Mannvit lead the design and commissioning of the CO₂ and H₂S abatement plant at Hellisheidi Geothermal Power Plant. The owner of the power plant is Orka Náttúrunnar (ON Power).
