Coal

Largest CCS Project in Operation

Companies continue to increase the size of carbon capture and sequestration test projects. Mitsubishi Heavy Industries (MHI) has launched operation of what it calls the world’s largest demonstration of carbon capture on a pulverized coal plant. The 25-MW coal-fired carbon capture facility at Southern Co.’s Plant Barry (Figure 4) is owned and operated by Alabama Power. The facility uses MHI’s KM CDR Process, and it is expected to capture nearly 150,000 tons of CO2 annually (500 tons/day) at a successful CO2 capture rate of over 90%. The CO2 will then be permanently stored underground in a deep saline geologic formation.

The facility consists of a flue gas scrubber, CO2 capture and utilization technology, CO2 compression machinery, and electrical components, among other features. MHI’s KM CDR Process technology uses an advanced solvent called KS-1 to capture the CO2 from a flue gas stack. The flue gas is directed to the KM CDR Process, where the KS-1 solvent reacts with and captures the CO2. CO2 can then be separated from the KS-1 and compressed for pipeline transport.
