1) Just one coal CCS project in operation
2) Not all CO2 is captured and stored
3) All CO2 storage projects involve oil/gas recovery

Carbon Capture and Storage:Can it make coal clean ?
?
Carbon dioxide Emissions
ProductLignite
• CCS can only address some of the CO2 from the process plant
• No storage site – chances of finding one and implementing CCS; unlikely
