  2. What do I mean by clean?

  3. What do I mean by clean? Mining Direct environmental impacts

  4. What do I mean by clean? Carbon dioxide Emissions Products: Fertiliser, Diesel Briquettes Lignite Mining Processing Direct environmental impacts

  5. What do I mean by clean? Carbon dioxide Emissions Products: Fertiliser, Diesel Briquettes Lignite Mining Processing Direct environmental impacts

  6. What do I mean by clean? Carbon dioxide Emissions Products: Fertiliser, Diesel Briquettes Lignite Mining Processing CCS applies to this bit only Direct environmental impacts

  7. Carbon capture and storage: What is it? Carbon Dioxide (CO2) Lignite coal Process plant

  8. Carbon capture and storage: What is it? Carbon Dioxide (CO2) Lignite coal Capture Process plant

  9. Carbon capture and storage: What is it? Carbon Dioxide (CO2) Lignite coal Capture Transport (pipeline) Process plant

  10. Carbon capture and storage: What is it? Carbon Dioxide (CO2) Lignite coal Capture Transport (pipeline) Process plant

  11. Carbon capture and storage: What is it? Carbon Dioxide (CO2) Lignite coal Capture Transport (pipeline) Process plant Storage in a depleted oil or gas field

  12. Carbon capture and storage: What is it? Carbon Dioxide (CO2) Lignite coal Capture Transport (pipeline) Process plant Storage in a depleted oil or gas field Or in a saline aquifer

  13. Carbon Capture and Storage: Is it being done? CO2 Synthetic natural gas and other chemicals Lignite Coal Great Plains Synfuels Plant North Dakota, USA,

  14. Carbon Capture and Storage: Is it being done? CO2 325km pipeline Near depleted Oil field Weyburn, Canada Synthetic natural gas and other chemicals Lignite Coal Great Plains Synfuels Plant North Dakota, USA,

  15. Carbon Capture and Storage: Is it being done? CO2 325km pipeline Near depleted Oil field Weyburn, Canada Synthetic natural gas and other chemicals Lignite Coal Great Plains Synfuels Plant North Dakota, USA, Other Non-Coal carbon capture and storage projects Natural gas processing North Sea, Norway Natural gas processing, Algeria

  16. Carbon Capture and Storage: Is it being done? CO2 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 Great Plains Synfuels Plant North Dakota, USA, Other Non-Coal carbon capture and storage projects Natural gas processing North Sea, Norway Natural gas processing, Algeria

  18. Carbon Capture and Storage for NZ’s Lignite Coal

  19. Carbon Capture and Storage for NZ’s Lignite Coal Lignite

  20. Carbon Capture and Storage for NZ’s Lignite Coal Gas (+some oil) Lignite

  21. Carbon Capture and Storage for NZ’s Lignite Coal Storage site: • No depleted gas/oil reservoirs close by • Unknown if other types of storage site exist Gas (+some oil) Lignite

  22. Carbon Capture and Storage for NZ’s Lignite Coal Storage site: • No depleted gas/oil reservoirs close by • Unknown if other types of storage site exist IF CCS did occur, not all CO2 would be captured Gas (+some oil) Lignite

  23. Carbon Capture and Storage for NZ’s Lignite Coal Storage site: • No depleted gas/oil reservoirs close by • Unknown if other types of storage site exist IF CCS did occur, not all CO2 would be captured Gas (+some oil) Lignite 2/3rd of NZ diesel Lignite

  24. Carbon Capture and Storage for NZ’s Lignite Coal Storage site: • No depleted gas/oil reservoirs close by • Unknown if other types of storage site exist IF CCS did occur, not all CO2 would be captured Gas (+some oil) 3.4 Mt/y Lignite 2/3rd of NZ diesel 2.6 Mt/y Lignite

  25. Carbon Capture and Storage for NZ’s Lignite Coal Storage site: • No depleted gas/oil reservoirs close by • Unknown if other types of storage site exist IF CCS did occur, not all CO2 would be captured Gas (+some oil) 3.4 Mt/y Lignite 2/3rd of NZ diesel 2.6 Mt/y Lignite = largest storage project in the world

  26. Carbon Capture and Storage:Can 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 Carbon dioxide Emissions Product Lignite ?
