CO2 aquifer research helping to identify safe carbon capture storage

Natural underground pools of carbon dioxide are providing clues on how best to store manmade greenhouse gas emissions. The findings of a worldwide research study will help further develop carbon capture and storage (CCS) technology, whereby CO2 from power stations is stored deep underground to stop them from contributing to climate change. Scientists from the Universities of Edinburgh and Strathclyde have analysed 76 natural CO2 reservoirs and identified the best geological conditions for long-term CO2 storage. Sites deeper than 1,200 metres, a high density of gas and thick rocks to cap reservoirs were all found to be beneficial. The findings will influence the selection and design of future CO2 storage sites.

Ancient rocks yield hard facts on safe storage of greenhouse gas

Natural underground reservoirs of carbon dioxide are giving scientists vital clues how best to store man-made emissions of the greenhouse gas.
