Carbon Capture and Storage fails to deliver

You may perhaps remember it, the International Energy Agency is banking a lot on carbon capture and storage (CCS). Indeed, the IEA believes that it could account for 15 % of greenhouse gases emissions reductions. However, CleanTechnica got an interesting article on how this solution fails to deliver. One of the main reasons is that …
