This technology is a platform for capturing atmospheric carbon dioxide in an ion exchange resin and subsequently releasing it into solution for storage.
Carbon emissions from fossil fuels are a source of global concern, and the reduction of these emissions is a complex issue that will involve both technological and geopolitical solutions. Carbon capture provides an alternative approach for the management and reduction of carbon emissions by removing existing carbon dioxide from the air. Current carbon capture technologies include forestation, ocean enrichment, or rock weathering, which require implementation on a massive scale to be effective. Alternatively, chemical pumps work on a smaller scale but are relatively inefficient and expensive to operate. A method to reduce the cost of releasing and condensing captured CO2 is necessary to make these solutions feasible.
This technology is a method to capture carbon dioxide from air using an anionic exchange. The resin is fabricated such that carbon dioxide can be captured when the resin is dry and subsequently released into solution upon washing, regenerating the resin for future capture. The technology includes a series of washing steps with water and alkaline solutions to improve the capacity for dissolved carbon dioxide in solution. The solution can then be collected for storage, and the resin can be dried for further use. This technology also has the potential to be used for low space, continuous run implementation designs.
