Novel molten/solid composite oxygen transport membranes for CO2 capture
The primary objective of MOC-OTM is to develop novel high flux oxygen separation membranes operating at intermediate temperatures for improving energy efficiency of oxygen combustion in CCS integrated power plants.
About the project
Many of current energy conversion and storage technologies utilize the fine interfaces between porous solid and functional ion-conducting liquid phases. Fundamental and microscopical understanding of how they work is, however, limited. Understanding of the properties of materials confined in constrained geometry is of fundamental interest, as surface interactions due to spatial restriction and low dimensionality of the confining matrix result in the physical and chemical behavior of the confined systems much different from the bulk. The MOC-OTM project addresses these challenges and takes as starting point the recent discoveries of new systems (e.g. dual phase gas separation membranes and apparent proton conduction in ceramics at room temperature pursued separately in preceding RCN projects) and advances in theory, modelling, and high resolution and in-situ instrumentation to call for a deeper and more generic investigation of the principles at hand. This will be exemplified in the present project with the development of high flux oxygen transport membranes operating at intermediate temperature to increase efficiency of oxygen combustion in CCS integrated power plants. The membranes will be designed as molten/solid composite systems exhibiting high oxygen flux density through confinement effects in microstructured solid phases. The project will contain theoretical and modelling activities, experimental studies of key materials systems and fabrication of microstructured ceramic matrices and composite membranes. Membranes will be tested in relevant conditions to evaluate their operating window and address stability of operation over 500h.
The project is led by SINTEF, with UiO, Colorado School of Mines, Imperial College London, University Twente, as national and international collaborators, and has an advisory board including Air Liquide, CoorsTeK Membrane Sciences and Cerpotech to ensure industrial relevance. It trains one PhD candidate and lasts for 3 years.
The project is financed by Norwegian research council , project number 268450
