Recently, carbon neutrality has been promoted as a potentially practical solution to global CO2 emissions and increasing energy‐consumption challenges. Many attempts have been made to remove CO2 from the environment to address climate change and rising sea levels owing to anthropogenic CO2 emissions. Herein, membrane technology is proposed as a suitable solution for carbon neutrality. This review aims to comprehensively evaluate the currently available scientific research on membranes for carbon capture, focusing on innovative microporous material membranes used for CO2 separation and considering their material, chemical, and physical characteristics and permeability factors. Membranes from such materials comprise metal‐organic frameworks, zeolites, silica, porous organic frameworks, and microporous polymers. The critical obstacles related to membrane design, growth, and CO2 capture and usage processes are summarized to establish novel membranes and strategies and accelerate their scaleup.

“…Fundamentally, two types of membranes, inorganic and polymeric membranes, are available. Inorganic membrane, which is synthesized from inorganic materials such as zeolite and metal–organic framework (MOF), possesses attractive gas separation performance as well as better chemical and thermal stability 8 . However, its brittleness, poor processability, and high fabrication cost make it less appealing commercially 9 .…”

Polyimide (PI), a glassy polymer, suffers from permeability–selectivity trade‐off and plasticization, which restrict its gas separation performance. Instead of exploring new materials, polymer blend and mixed matrix membrane (MMM) emerge as promising approaches in improving membrane gas separation efficiency attributed to their simplicity and cost efficiency. However, polymer immiscibility and polymer‐filler incompatibility are the main challenges encountered in these two approaches, respectively. Thus far, only limited reviews target the comparison between PI/glassy and PI/rubbery polymer blends. Besides, the review on improving the compatibility between polymer and filler in PI‐metal–organic framework (MOF) MMM is also lacking. Hence, this review aims to assess the gas separation characteristics of PI blended with glassy and rubbery polymers, focusing on the blend miscibility. It was discovered that the casting solvent's solubility parameter and solvent volatility play a part in governing the blend miscibility. Meanwhile, the efficiency of surface functionalization and ionic liquid addition in improving the polymer–filler compatibility in MMM is also reviewed. The wet method for filler incorporation demonstrates a more homogeneous filler dispersion within the membrane. Hence, its employment in MOF‐based MMM fabrication can be explored further.

“…This calls for the separation of pure hydrogen from the product gases of SMR, which can be realized via a number of technologies, such as pressure swing adsorption − or through the use of a galvanic hydrogen pump employing a perovskite based protonic ceramic membrane. − For the former techniques, hydrogen permeation occurs under a high pressure gradient across a selective metal-based membrane (usually composed of palladium or its alloys with a thickness of 10–15 μm) or molecular sieves . Although an established hydrogen purification technology operates well at large scales with a high pressure gradient (5–20 bar) across the membrane, it is capital and energy intensive.…”

Protonic ceramic solid oxide cells (P-SOCs) have gained widespread attention due to their potential for operation in the temperature range of 300–500 °C, which is not only beneficial in terms of material stability but also offers unique possibilities from a thermodynamic point of view to realize a series of reactions. For instance, they are ideal for the production of synthetic fuels by hydrogenation of carbon dioxide and nitrogen, upgradation of hydrocarbons, or dehydrogenation reactions. However, the development of P-SOC is quite challenging because it requires a multifront optimization in terms of material synthesis and fabrication procedures. Herein, we report in detail a method to overcome various fabrication challenges for the development of efficient and robust electrode-supported P-SOCs (Ni-BCZY/BCZY/Ni-BCZY) based on a BaCe 0.2 Zr 0.7 Y 0.1 O 3−δ (BCZY271) electrolyte. We examined the effect of pore formers on the porosity of the Ni-BCZY support electrode, various electrolyte deposition techniques (spray, spin, and vacuum-assisted), and thermal treatments for developing robust and flat half-cells. Half-cells containing a thin (10–12 μm) pinhole-free electrolyte layer were completed by a screen-printed Ni-BCZY electrode and evaluated as an electrochemical hydrogen pump to access the functionality. The P-SOCs are found to show a current density ranging from 150 to 525 mA cm –2 at 1 V over an operating temperature range of 350–450 °C. The faradaic efficiency of the P-SOCs as well as their stability were also evaluated.
