Techno-Economic Assessment for a Composite Hollow Fiber Membrane Process for Post Combustion CO2 Capture

GE Global Research, Idaho National Laboratory (INL), Georgia Institute of Technology (Georgia Tech), and Western Research Institute (WRI) are developing high performance polymer composite hollow fiber membranes for economical post-combustion carbon dioxide (CO₂) capture from pulverized coal flue gas at temperatures typical of existing flue gas cleanup processes. Composite membranes are being developed and optimized at the bench scale by coating novel phosphazene polymer coatings on fabricated hollow fiber supports.

We describe the technical and economic feasibility analyses to evaluate the impact of integrating a membrane in a PC boiler. The energy penalty (EP) and increase in cost of electricity (COE) for 90% carbon capture will be discussed. Different scenarios based on membrane properties and system designs will be presented that impact both EP and COE.
