Iceland, perhaps the world leader in geothermal technology, is launching a project to store carbon dioxide. Reykjavik Energy is building a 300 MW Hellisheidi geothermal power station near the Hengill geothermal area, which will be the site of the CO2 storage project. The project will separate unwanted CO2 from the plant and pump it into basalt lava fields, where a chemical reaction will take place turning the CO2 into calcite, a solid, inert crystal. Reykjavik Energy's Holmfriour Siguroardottir said, "Basaltic rocks are among the most reactive rock types of the earth's crust. The rocks contain reactive minerals with a very high potential for CO2 sequestration."
