Gas Technology Institute (GTI) is developing a transformational graphene oxide (GO)-based membrane process that can be installed in a new or retrofitted into an existing pulverized coal or natural gas power plant for carbon dioxide (CO2) capture ready for demonstration by 2030. The expected product from this project will be a compact, GO-based membrane prototype system capable of achieving at least 70% CO2 removal with a single-stage process and 90% CO2 removal with a two-stage process. The system will be tested over an extended duration on actual flue gas at GTI and the National Carbon Capture Center (NCCC).
