A new study has shown that using GE Vernova’s exhaust gas recirculation (EGR) system can reduce carbon capture costs.
In the study, the James M. Barry Electric Generating Plant, situated at Alabama Power in Bucks, Alabama, was retrofitted with GE Vernova’s exhaust gas recirculation (EGR) system.
In collaboration, study participants Southern Company, Linde, BASF and Kiewit showed that integrating the EGR system, which can capture up to 95% of a plant’s CO2 emissions, could lead to a reduction of more than 6% of the total cost of the carbon capture facility. This is as compared to installing carbon capture without the EGR system.
As well as employing GE Vernova’s EGR system, which reintroduces part of the exhaust gas back into the gas turbine inlet, the study explored GE Vernova measures and technologies including the use of NGCC steam in the carbon capture system facility, potential gas turbine upgrades, and installing NGCC and carbon capture control systems.
The official findings were released by the U.S. Department of Energy’s (DOE) Office of Fossil Energy and Carbon Management.
