Carbon dioxide levels in our atmosphere reached 415 parts per million for the first time in human history. A short term solution to reduce anthropogenic carbon dioxide emissions is through carbon capture and storage (CCS). CCS is a clean energy technology that aims to capture carbon dioxide (CO2) emissions from industrial facilities before they are released into the atmosphere and contribute to global warming.In this research project, we propose an innovative graphene-based hybrid aerogel with enhanced CO2 capturing capabilities (~ 2 mmol of CO2 per gram of adsorber). We also develop an innovative scalable manufacturing solution for mass production of the optimized aerogel. This manufacturing solution enables microstructural control of the aerogel producing an optimized active surface area for CO2 capture. This processing scheme will enable our technology to move quickly from lab scale to pilot scale testing. Moreover, the aerogel proposed being based on graphene can be regenerated by Joule heating. This enables modular design in future industrial operations which will reduce capital costs, down times and energy demands. CCS technology are urgently required in Alberta and Canada considering the energy intensity oil sands operations, the large concrete and cement industries and the large capital investments already deployed in Canada. Our solution is complementary and has disruptive potential to rethink CO2 capturing operations. Moreover, our solution enables CCS to be easily retrofitted in established facilities with minor investments.The HQP involved in this research will develop skills in CO2 capturing, nanomaterial synthesis and processing and material characterization techniques. These skills are in high demand in Alberta and Canada considering the growing aerospatial, biomedical and nanocomposite industries in addition to the established energy sector.
