Burying CO2 safer

Storing carbon dioxide in reservoirs deep underground may be better for  climate than emitting the gas directly into atmosphere as researchers have found that this process is much safer over long periods of time than previously thought. The researchers found that natural accumulations of CO2 that have been trapped underground for around 100,000 years have not significantly corroded the rocks above. These findings, published in a journal, demonstrate the viability of a process called carbon capture and storage (CCS) as a solution to reducing carbon emissions from coal and gas-fired power stations, the researchers said.
