Geological carbon sequestration - silver bullet or pipe dream?
Drastically cutting carbon dioxide emissions while continuing to rely on fossil fuels may sound like having your cake and eating it. But carbon capture and storage - separating carbon dioxide from flue gases or natural gas and storing it in geological formations - opens the door to just that future. Despite its complexity, the idea is gaining some heavyweight supporters. A research collaboration between nine oil companies with backing from the EC and the US and Norwegian governments hopes to make it economically viable within three years.
