Carbon Capture and Storage - can it make coal clean? Dr. Shannon Page Department of Environmental Management Lincoln University
3
What do I mean by clean?
4
Mining Direct environmental impacts
5
What do I mean by clean? Mining Processing Direct environmental impacts Products: Fertiliser, Diesel Briquettes Lignite Carbon dioxide Emissions
6
What do I mean by clean? Mining Processing Direct environmental impacts Products: Fertiliser, Diesel Briquettes Lignite Carbon dioxide Emissions
7
What do I mean by clean? Mining Processing Direct environmental impacts Products: Fertiliser, Diesel Briquettes Lignite Carbon dioxide Emissions CCS applies to this bit only
8
Carbon capture and storage: What is it? Lignite coal Carbon Dioxide (CO 2 ) Process plant
9
Carbon capture and storage: What is it? Lignite coal Carbon Dioxide (CO 2 ) Capture Process plant
10
Carbon capture and storage: What is it? Lignite coal Carbon Dioxide (CO 2 ) Capture Transport (pipeline) Process plant
11
Carbon capture and storage: What is it? Lignite coal Carbon Dioxide (CO 2 ) Capture Transport (pipeline) Process plant
12
Carbon capture and storage: What is it? Lignite coal Carbon Dioxide (CO 2 ) Capture Transport (pipeline) Process plant Storage in a depleted oil or gas field
13
Carbon capture and storage: What is it? Lignite coal Carbon Dioxide (CO 2 ) Capture Transport (pipeline) Or in a saline aquifer Process plant Storage in a depleted oil or gas field
14
Lignite Coal Synthetic natural gas and other chemicals CO 2 Great Plains Synfuels Plant North Dakota, USA, Carbon Capture and Storage: Is it being done?
15
Lignite Coal Synthetic natural gas and other chemicals CO 2 Near depleted Oil field Weyburn, Canada 325km pipeline Great Plains Synfuels Plant North Dakota, USA, Carbon Capture and Storage: Is it being done?
16
Lignite Coal Synthetic natural gas and other chemicals CO 2 Near depleted Oil field Weyburn, Canada 325km pipeline Great Plains Synfuels Plant North Dakota, USA, Other Non-Coal carbon capture and storage projects Carbon Capture and Storage: Is it being done? Natural gas processing North Sea, Norway Natural gas processing, Algeria
17
Lignite Coal Synthetic natural gas and other chemicals CO 2 Near depleted Oil field Weyburn, Canada 325km pipeline Great Plains Synfuels Plant North Dakota, USA, Other Non-Coal carbon capture and storage projects Carbon Capture and Storage: Is it being done? Natural gas processing North Sea, Norway Natural gas processing, Algeria 1) Just one coal CCS project in operation 2) Not all CO 2 is captured and stored 3) All CO 2 storage projects involve oil/gas recovery

19
Carbon Capture and Storage for NZ’s Lignite Coal
20
Lignite
21
Carbon Capture and Storage for NZ’s Lignite Coal 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 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 CO 2 would be captured Gas (+some oil) 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 CO 2 would be captured Gas (+some oil) Lignite 2/3 rd of NZ diesel 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 CO 2 would be captured Gas (+some oil) Lignite 2/3 rd of NZ diesel Lignite 3.4 Mt/y 2.6 Mt/y
26
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 CO 2 would be captured Gas (+some oil) Lignite 2/3 rd of NZ diesel Lignite 3.4 Mt/y 2.6 Mt/y = largest storage project in the world
27
Carbon Capture and Storage: Can it make coal clean ? ? Carbon dioxide Emissions Product Lignite CCS can only address some of the CO 2 from the process plant No storage site – chances of finding one and implementing CCS; unlikely
