The Objectives


Since year 2007, scientists have collaborated with Reykjavík Energy’s experts, technicians, and tradespeople on developing the idea and implementation of fixating CO2 into basaltic rock around The Hellisheidi Geothermal Power Plant. The power station co-generates electricity and hot water from geothermal steam which contains sporadic amounts geothermal gases. The same method as has been developed with CO2 is now also employed to sequester H2S, another geothermal gas. Already, 60% of the gases are now fixed as minerals in the bedrock and ON Power, Reykjavík Energy’s subsidiary that operates the power plant, aims at making the operation traceless in terms of these gases.

The CarbFix2 project builds on the success of the CarbFix project. The CarbFix2 goal is to move the demonstrated CarbFix technology from the demonstration phase, to a general and economically viable complete CCS chain that can be used through Europe, and throughout the world. 

Towards this goal CarbFix2 will extend the original CarbFix approach from the demonstration stage in one location to implementation under more diverse conditions, with special emphasis on the sea-bed. Because the methods employed to fix CO2 in the bedrock crave both water and basaltic rock, scientists now have focused on the ocean floor. There, extensive field of basalt can be found and, naturally, lots of water. To significantly lower the cost of CCS, major effort in CarbFix2 is focused on optimising the capture and storage of impure CO2, using a novel water based technique, providing an added value to CCS. By meeting these goals, the CarbFix2 project can increase the safety, and geographical and economical applicability of CCS.
