325km pipeline
Near depleted Oil field Weyburn, Canada
Synthetic natural gas and other chemicals
Lignite Coal
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 for NZs Lignite Coal

• Storage site
• No depleted gas/oil reservoirs close by
• Unknown if other types of storage site exist

Carbon Capture and StorageCan it make coal
clean ?

• CCS can only address some of the CO2 from the
  process plant
• No storage site chances of finding one and
  implementing CCS unlikely
