Turning CO2 Into Rock
It's not looking good for avoiding the impact of climate change. However, science may step up and provide us with some solutions. For example, The technology that turns CO2 into rock Iceland may have uncovered [a] truly safe method for carbon capture and storage. CO2 reacts with mineral-rich rocks to turn into a solid. [R]esearchers in Iceland have developed a method by which CO2 is dissolved in water before being injected into the island’s mineral-rich, basaltic rocks. Here, it turns into solid white calcite crystals in far less than 100,000 years — in fact, it takes just two years. This is not just theoretical or lab-based research. It has been happening on an industrial scale at CarbFix, part of the Hellisheidi geothermal power plant, near Reykjavik, since 2014. Waste CO2 is captured from the power plant’s steam, is dissolved into large volumes of water and injected into the basalt below, between 400m and 800m deep. There the basalt (which contains up to 25...
