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.

我们大气中的二氧化碳水平在人类历史上第一次达到百万分之415。减少人为二氧化碳排放的短期解决方案是通过碳捕获和封存(CCS)。CCS是一种清洁能源技术，旨在捕获工业设施排放的二氧化碳(CO2)，然后再排放到大气中，从而导致全球变暖。在本研究项目中，我们提出了一种创新的基于石墨烯的混合气凝胶，具有增强的二氧化碳捕获能力(每克吸附器约2 mmol二氧化碳)。我们还开发了一种创新的可扩展制造解决方案，用于大规模生产优化的气凝胶。这种制造解决方案能够实现气凝胶的微观结构控制，产生用于捕获二氧化碳的优化活性表面积。这一处理方案将使我们的技术能够迅速从实验室规模转移到中试规模测试。此外，所提出的基于石墨烯的气凝胶可以通过焦耳加热进行再生。这使得模块化设计在未来的工业运营中得以实现，这将减少资本成本、停机时间和能源需求。考虑到能源密集型油砂作业、大型混凝土和水泥行业以及加拿大已经部署的大量资本投资，艾伯塔省和加拿大迫切需要CCS技术。我们的解决方案是相辅相成的，具有颠覆性的潜力，可以重新考虑二氧化碳捕获操作。此外，我们的解决方案使CCS能够以较小的投资轻松地在现有设施中进行改造。参与这项研究的HQP将发展二氧化碳捕获、纳米材料合成和加工以及材料表征技术方面的技能。考虑到航空航天、生物医学和纳米复合材料行业的发展，以及现有的能源部门，艾伯塔省和加拿大对这些技能的需求很高。
