Description
Summary:The objective of the “MEM-BRAIN” project is the development and integration of ceramic and polymeric gas separation membranes for zero-emission fossil power plants. This will be achieved using membranes with a high permeability and selectivity for either CO 2, O 2 or H 2, for the three CO 2 capture process routes in power plants, thus enabling CO 2 to be captured with high-purity in a readily condensable form. For the pre-combustion process, we have developed ceramic microporous membranes that operate at intermediate temperatures (≤400 °C) for H 2/CO 2 separation. For the oxyfuel process, we have developed dense ceramic mixed oxygen ionic-electronic conducting membranes that operate at 800–1000 °C for O 2/N 2 separation. The perovskite-type oxide Ba 0.5Sr 0.5Co 0.8Fe 0.2O 3−δ (BSCF5582) was taken as the reference material for this application. For the post-combustion process, polymeric and organic/inorganic hybrid membranes have been developed for CO 2/N 2 separation at temperatures up to 200 °C. In addition to the development of membranes, we consider the integration of the membranes into power plants by modelling and optimization. Finally, specific technical, economic and environmental properties of CO 2 capture as a component in a CCS process chain are assessed, analysing the energy supply system as a whole.
