TABLE 1Costs of different capture and disposal optionsStorage 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.
