Material synthesis
(contact: Monika Pilz, monika.pilz@sintef.no)
The development of materials for pre-combustion processes entails the modification and optimization of the innovative hybrid iPOSS membranes for the separation of H2 from the CO2/CO/CH4 components. In GENESIS, the iPOSS technology will be investigated for H2/CO2 separation from coke gas.
iPOSS carbon capture systems for pre-combustion will be optimized for cost-effective scale-up. The strategy aims at optimizing the iPOSS (polyPOSS-imide) thermal stable membrane layer for high permeances and H2/CO2 selectivity. Special attention will be taken to achieve a defect free layer on the ceramic support.
The unique properties of the thin iPOSS membranes received through interfacial polymerization depends on the alternating connections between the organic bridges and the POSS cages.
In GENESIS, SINTEF designs and synthesizes hybrid organic inorganic nanostructures based on FunzioNano®-POSS, using a patented 2-step procedure developed as a technology platform during the last 20 years. The focus is on synthesis methods that allow a cost-efficient production at large scale.

The synthesis of the hybrid POSS nanostructures is conducted via controlled sol-gel conversion upon hydrolysis and condensation of the selected (mixed) alkoxysilane(s) yielding the targeted cage structures. The best formulation of POSS with distinct bridges between the POSS cages and amino groups that is soluble in suitable solvents will be selected for the fabrication and optimization of iPOSS (polyPOSS-imide) as defect-free and stable 100 nm membrane layer on single ceramic support at lab scale and used for scale-up to multichannel supports. The effect of FunzioNano®-POSS on the thermal stability, rigidity, CO2 permeability and selectivity of the iPOSS membranes is studied and optimized.

Membrane and material testing
(contact: Thijs Peters, thijs.peters@sintef.no)
In GENESIS, SINTEF is responsible for the long-term stability testing of both the iPOSS and MOF MMM membranes in the presence of contaminants. Gas permeation experiments are performed applying either the constant-volume variable-pressure (time-lag) method along standard ASTM D1434-82 to obtain solution/diffusion data, or through the constant-pressure method, analogue to ASTM D3985 – 17, though employing gas chromatography (GC) analysis on the permeate stream. The influence of poisonous gases is conveniently studied in the ECCSEL NO3.3 MLAB infrastructure.

Live cycle assessment (LCA)
(contact: Sidsel Meli Hanetho, sidselmeli.hanetho@sintef.no)
In GENESIS, SINTEF assesses the life cycle of the IPOSS membranes according to ISO 14040 and 14044 standards for life cycle assessment. The environmental impacts of the IPOSS membranes are quantified and compared against state-of-the-art carbon capture technology. Environmental benefits and trade-offs between the technologies and impact categories are discussed and compared.
