Urgent actions are needed to reduce CO2 emissions and mitigate the increasingly severe impacts of climate change. Since 1990s, membrane research group (MEMFO) at Norwegian University Science Technology has been committed developing effective membranes processes for separation. MEMFO's can be categorized into five main themes: facilitated transport membranes, hybrid carbon contactors, related modeling process simulation. These themes tied industrial applications in capture from flue gas, biogas upgrading, natural gas sweetening, hydrogen purification. Promising identified based on their laboratory-scale performances, have selected onsite testing validate performances as well stability durability. Verified upscaled pilot tests. This account paper summarizes development outcomes over past decade discusses our strategies perspectives future work.

In this work, a membrane separation process is designed and optimized to purify dark fermentative biohydrogen by removing CO2. A CO2-selective PVAm-based nanocomposite was selected considering its high CO2/H2 performance unique features suitable for the process. We tested performances under conditions provide more accurate simulation basis. Several design scenarios were investigated. two-stage with recycle stream determined as optimal design, in which specific cost purifying H2 99.5 vol% loss of <10% reaches only 0.156 $/Nm3. The techno-economic feasibility study purification simultaneous CO2 capture also performed through an alternative introducing 3rd-stage using same or H2-selective membrane. Adding can side product various purities, further decreases loss, leading additional economic benefits.
