CondAlign has been developing gas separation membranes since 2018. The technology builds upon the same principals as the alignment process used for electrically or thermally conductive films.
CondAlign filed two patent applications in 2019 on membranes for gas separation. Gas separation membranes available today, which have high permeability, are not selective enough to be competitive with conventional CCS systems. Insufficient selectivity causes too much of the unwanted gas to pass through, hampering further processing.
Combating climate change
Carbon capture and storage, CCS, is a necessary technology to combat climate change. Efficient and cost-effective membrane-based CO2 capture is one of the processes that is needed to make that happen.
The International Energy Agency has estimated that 3,400 CCS plants will be needed globally by 2050 to fulfil the Paris agreement and keep the global temperature rise below 2 degrees Celsius. CondAlign strives to be a part of the solution.
Gas separation membranes for small scale installations
Gas separation by polymeric membranes is attractive from a process standpoint, as they offer smaller footprint and do not require the use of harmful chemicals. This makes the technology appealing for industrial applications.
Furthermore, smaller facilities such as farms, waste plants and bio-refineries are huge contributors to greenhouse gas emissions. CondAlign’s future membrane modules are compatible with and economically viable for small scale installations.
In the MembrAlign project, CondAlign develops new and improved gas separation membranes, with selectivity of more than 100. This means that for every 100 parts of CO2 transported through the membranes, no more than 1 part of nitrogen or methane can pass.
The increased selectivity will be achieved by embedding advanced nanoparticles within the polymeric matrix to improve the separation performance.
The MembrAlign project
The project started in 2018 and is partly funded by the Research Council of Norway. It combines the membrane competence of SINTEF Industry and the membrane team at NTNU, with CondAlign's alignment technology. If successful, the project will lead to ground-breaking materials and processes that will enable next generation gas separation membranes.
CondAlign Capture elevates the importance of CondAligns work with gas separation membranes. It has the potential of developing a break-through product that enables CCS locally.
