Reykjavík Energy along with the University of Iceland and other international scientific institutions have received two EU grants for climate projects to the combined amount of EUR 12.2 million. The grants will fund further development of methods fixing CO2 as a mineral in basaltic rock, now with special emphasis on the sea-bed.
Dr. Edda Sif Pind Aradóttir, the projects’ manager at Reykjavík Energy, says the grants, that will benefit a score of collaborators, are a valuable recognition of the projects’ merit and their contribution in the fight against climate change. Already, nine doctoral students have done their theses on fixing CO2 in rock.
Gas into rock
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.
Looking to the oceans
Because the methods employed to fix the geothermal gases 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.
