“…The feasibility of several hybrid concepts for CO 2 capture such as membrane–PSA and membrane–distillation have been investigated . A promising hybrid system with potential energy savings has recently been developed by American Air Liquide, by which subambient‐temperature (−50 to −20 °C) CO 2 capture is performed through a hybrid membrane–cryogenic distillation process . This hybrid process aims at retrofitting existing pulverized coal‐fired power plants and is sought to enhance both the productivity and selectivity of the membrane module, which thus reduces both the energy and capital costs of the capture process.…”

In recent years, carbon capture and utilization (CCU) has been proposed as a potential technological solution to the problems of greenhouse‐gas emissions and the ever‐growing energy demand. To combat climate change and ocean acidification as a result of anthropogenic CO2 emissions, efforts have already been put forth to capture and sequester CO2 from large point sources, especially power plants; however, the utilization of CO2 as a feedstock to make valuable chemicals, materials, and transportation fuels is potentially more desirable and provides a better and long‐term solution than sequestration. The products of CO2 utilization can supplement or replace chemical feedstocks in the fine chemicals, pharmaceutical, and polymer industries. In this review, we first provide an overview of the current status of CO2‐capture technologies and their associated challenges and opportunities with respect to efficiency and economy followed by an overview of various carbon‐utilization approaches. The current status of combined CO2 capture and utilization, as a novel efficient and cost‐effective approach, is also briefly discussed. We summarize the main challenges associated with the design, development, and large‐scale deployment of CO2 capture and utilization processes to provide a perspective and roadmap for the development of new technologies and opportunities to accelerate their scale‐up in the near future.

“…Also, all permeation selectivities are ideal values that are based on the measurement of individual gases. Although humidity can have a detrimental effect on the permeability properties of PEMs, it has already been shown by other researchers that all water vapor can be effectively removed from flue gas using drying agents and that regeneration of the agents do not require the input of additional energy; i. e., advantage can be taken of the heat of combustion …”

“…Because of the known ability of poly(ethylene oxide)‐based polymers to favor the permeation of CO 2 over N 2 due to favored solubility, we were motivated to design hyperthin polyelectrolyte multilayers that were rich in poly(ethylene oxide) . With this goal in mind we devised an ion linker strategy that allowed us to form polyelectrolytes that were suitable for LbL deposition.…”

Thin film formation via the Layer‐by‐Layer method is now a well‐established and broadly used method in materials science. We have been keenly interested in exploiting this technique in the area of gas separations. Specifically, we have sought to create hyperthin (<100 nm) polyelectrolyte‐based membranes that have practical potential for the separation of CO2 from N2 (flue gas) and H2 from CO2 (syngas). In this personal account, we summarize recent studies that have been aimed at measuring the influence of a variety of factors that can affect the permeability and permeation selectivity of hyperthin polyelectrolyte multilayers (PEMs).

Carbon capture and storage has declined in prominence as a large scale response to climate change, but carbon dioxide capture will remain important into the future for the hydrogen economy, for steel and cement, as well as chemical production. Membrane technology can be a significant component of this industry if cost competitive. While most scientific research is focussed on developing novel materials for this application, it is the process design of the membrane operations that is much more critical in reducing these costs. In post combustion capture, this involves optimisation of the pressure driving force across the membrane, either through feed compression or permeate vacuum pumping, integration of downstream cryogenic purification and the use of combustion air sweeps. In pre-combustion capture, integration of the membrane into the water gas shift reactor is key. Membrane contactors can also play a role, but must be carefully engineered to ensure pressure drop control and to minimise capillary condensation of water.
