The project, which is a continuation of the CLIMIT project (KMB) “Clean Energy by using High Performance Membranes” (CEPEME), will verify that low pressure fixed site carrier (FSC) membranes can be used for CO2 capture from typical power plant sources. This is done through further development of NTNU’s patented FSC membrane technology.
The membrane that is focused on is a composite membrane where the membrane itself is a very thin layer of polyvinylamine (PVAm), where the amine group is a “carrier” that contributes to CO2 being transported quickly through the membrane when it is wet. This gives the membrane superior separation properties over a conventional polymer membrane.
The performance of the membrane material has been demonstrated by experiments in a laboratory scale pilot module. Very good separation properties were shown, and the membrane has very high selectivity for CO2. Based on data from the pilot module and techno-economic assessments, the technology has shown a potential to reduce the cost of CO2 capture on a commercial scale. In order to evaluate the potential further, there is a need to test the membrane under realistic process conditions. Therefore, a hollow fiber module should be built in a next project phase, and it is recommended that commercial suppliers be brought in as partners in the next development phase.
