For years we have been trying to find different ways to limit carbon dioxide produced from fossil fuels. Some researchers believe that things would be very convenient if we could just deposit carbon dioxide in rocks. A pilot project around this idea has shown an impressive result
. John Ross, reporting for the Australian: Scientists say they have demonstrated a foolproof way of sequestering atmospheric carbon dioxide -- turning it into rock. An international team of researchers says it has demonstrated for the first time that CO2 can be permanently locked away from the atmosphere by injecting it into volcanic bedrock. The study, reported this morning in the journal Science, could overcome the leakage problems that have plagued attempts to bury CO2 gas underground. Lead author Juerg Matter said between 95 per cent and 98 per cent of the injected CO2 had been mineralised in less than two years, "which is amazingly fast."
"Until now it was thought this process would take hundreds to thousands of years," University of Southampton, which led the new study, said in a statement. "The current study has demonstrated that it can take as little as two years."
