In a novel way to fight global warming, scientists are trying how they could remove excess carbon dioxide from the atmosphere and store the gas deep under the sea bed where it can cause no trouble.
Researchers at the University of Iceland are studying the possibility of sequestration of carbon dioxide (CO2) in basalt, a common extrusive volcanic rock that makes up most of the world’s oceanic crust.
Sequestration is the carbon-capturing method which involves injecting the gas directly into underground geological formations. Oil fields, gas fields, saline formations, unminable coal seams, and saline-filled basalt formations have been suggested as storage sites.
Sigurdur Gislason, of University of Iceland, who is is leading an international team of scientists on the “Carbfix Project” for an Icelandic geothermal power plant, presented his findings today at the annual Goldschmidt Conference at the University of Tennessee, Knoxville.
