Scientists try to convert CO2 into solid magnesite
Researchers at Stanford University, in the United States, believes his latest study, conducted in an abandoned mine in California, can help create solutions to a very important issue: how to store the carbon emitted by human activities?The team spent two years trying to unravel a mystery in the mine geological Red Mountain, located about 100 km from Palo Alto, California. In it, are some of the largest veins of pure magnesium carbonate, a mineral made of carbon dioxide (CO2) and magnesium. The big question was trying to find out how these veins were formed, millions of years ago.Researchers have proposed a solution that could lead to a new technique to convert carbon dioxide, a potent greenhouse gas, in solid magnesite. In fact, the conventional geological armazamento involves the capture of CO2 from industrial chimneys â€" and its injection as subsurface fluid. But there's a big concern: prevent CO2 leak back into the atmosphere. So, the solution found through convert CO2 into a stable mineral.According to the sustainable planet, one of the most difficult parts of the task goes through from the rock to accommodate the C02. "And this may require brute force. This type of violent rupture happened in the region studied, with the intense geological activity millions of years ago in coastal California mountain chain, near the famous San Andreas fault. The idea is to replicate this process, "explains the site.The mine had 140 thousand metric tons of CO2 equivalent, before the magensita were mineralized in the early 20th century. The whole area could contain 13 gigatonnes of carbon.Human activity put in the atmosphere more than 500 gigatons of carbon. According to scientists, an irreversible change of climate is expected to happen around 1000 gigatons, a threshold for which humanity walks up to the middle of this century.
