Mannvit worked on the development of Climeworks' direct air capture plants, that capture CO2 directly from ambient air. Climeworks’ plant called ORCA, was inaugurated in September 2021. The ORCA plant was the world’s first and largest climate-positive direct air capture (DAC) and storage plant, making direct air capture and storage a reality. Climeworks works with the Icelandic innovation company Carbfix to store 4,000 tonnes of CO2 from the atmosphere each year in Hellisheidi after the ORCA plant became fully operational. 

Carbfix stores the carbon dioxide by injecting it into rock layers, where it mineralizes (turns into stone). The plants are located within the Geothermal Park ON. The entire opening event of the ORCA plant can be viewed here

Mannvit has also worked closely with OR, the owner of Carbfix, for over 15 years in research, testing and development of technology for pumping CO2 into the bedrock. Mannvit's field of work in the Carbfix project has been supervision and coordination of design, supervision of construction, installation and supervision during start-up, P&ID and more.
