Infographic: Looking for Capturable Carbon
Not all carbon emissions can be sequestered economically.
Access to a geologic storage site—or at least a pipeline that could reach it—was a limitation for many of the technically qualifying plants. Another limit is the projected cost of capture, which ranges from less than $20 a ton for ethanol and gas processing plants to $59 a ton for a steel mill.
Together, those 418 plants produce 358 million metric tons of capturable CO2, a far cry from the more than 2,500 million tons produced by all stationary sources.
