Awarded: NOK 8.1 mill.

This project aims to research and develop improved H2 selective membrane materials for integration in pre-combustion decarbonisation process schemes, thereby targeting the priority areas in CLIMIT. Hydrogen selective membranes have frequently been studie d in membrane reactors for water-gas shift (WGS-MR) and steam reforming (SR-MR) reactions to simultaneously achieve a high CO or methane conversion and production of pure H2. A key feature of this process intensification, achieving pre-combustion decarbon isation, is that such a membrane reactor would produce both a high pressure CO2 stream, and high-purity H2 for power generation. This can greatly facilitate the economics of power generation with carbon sequestration, as recently been demonstrated by the 6th FP EU-CACHET Project . The CACHET European project evaluated and benchmarked CO2 capture technology on an aligned and consistent basis, and concluded that the WGS-MR has the highest efficiency and highest cost reduction potential of all the evaluated technologies for natural gas pre-combustion, low CO2 carbon power generation. The project projected that an integrated membrane WGS reactor increases the energy efficiency by ~6%pt and reduces the cost of CO2 capture by ~30% compared to state-of-the-art t echnology. The concept has also been proven to be an efficient technology for hydrogen production combined with CO2 capture, and is pursued by companies in the US, Japan and Europe. The partners basic knowledge in this field has been built to a high leve l through funding by the Research Council of Norway and the EU. The present project proposes extensive efforts to pursue these fundamental topics further by bridging the gap between theory and application of these material systems, thereby strengthening t he competiveness of the technology.
