Costs of different capture and disposal options

Storage potential in the ocean and in geological formations is largest, but these options are also the most expensive. Further research may narrow down cost-range estimates.

CO2 mitigation option Reduction potential (million metric tons CO2) Net cost (in 1990 dollars; $/metric ton CO2 emissions avoided)
High Low
Capture with utilizationa 20 5 0
Capture with enhanced oil recovery 50 45 10
Capture (industrial sources) with storage 80 76 24
Capture with geological storageb 900 91 31
Capture with ocean storagec 600 91 31

a Capture options refer to power plants, except as noted. Utilization refers to food industry use and soda ash production.
bIncludes storage under the ocean.
cDirect injection into the ocean.
