The National Energy Technology Laboratory’s Research and Innovation Center (NETL-RIC) is assessing the potential of integrating small-scale modular pre-combustion carbon dioxide (CO2) capture processes with small-scale modular coal gasification technologies. The research is focused on the development of a hybrid process combining hydrogen (H2)-selective membranes followed by solvent capture for CO2. NETL-RIC is developing an H2-selective cross-linked polyamide nanofilm-based composite membrane for upstream CO2 capture. NETL-RIC is also investigating the corrosion rates in carbon and stainless steels from solvent-based pre-combustion carbon capture processes.
