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.

大气中的二氧化碳含量在人类历史上首次达到百万分之 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储存（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)，防止其释放到大气中并导致全球变暖。 在这个研究项目中，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 CO2 捕获能力（每克吸附剂约 2 mmol CO2）。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。该制造解决方案能够对气凝胶进行微观结构控制，从而为二氧化碳捕获产生优化的活性表面积。这种处理方案将使我们的技术能够快速从实验室规模转向中试规模测试。此外，所提出的基于石墨烯的气凝胶可以通过焦耳加热再生。这使得未来工业运营中的模块化设计成为可能，从而降低资本成本、停机时间和能源需求。 考虑到加拿大油砂作业的能源强度、大型混凝土和水泥工业以及加拿大已部署的大量资本投资，阿尔伯塔省和加拿大迫切需要 CCS 技术。我们的解决方案是互补的，并且具有重新思考二氧化碳捕集操作的颠覆性潜力。此外，我们的解决方案使 CCS 能够以少量投资轻松地在现有设施中进行改造。 参与这项研究的总部将开发二氧化碳捕获、纳米材料合成和加工以及材料表征技术方面的技能。考虑到除了成熟的能源行业之外，航空航天、生物医学和纳米复合材料行业也在不断发展，这些技能在艾伯塔省和加拿大的需求量很大。
