Climate change is arguably the greatest challenge of our generation, and the need to mitigate CO2 emissions is urgent. Since electricity generation from burning fossil fuels accounts for 40% of the world's CO2 emissions, almost all serious green house gas mitigation strategies include carbon capture and storage (CCS) as a key component of the plan. To date, large scale CCS has yet to be realized, in large part due to the fact that separating CO2 from the flue gas with current technologies requires too much energy. Implementing such technologies would consequently lead to a 60-80% increase in the cost of electricity. To address these issues, nanoporous metal-organic frameworks (MOF) and covalent organic frameworks (COF) have attracted a great deal of attention, as they have the potential to represent energy efficient CO2 scrubbers as a result of their record breaking internal surface areas and their highly tunable nature. Studies have suggested that by choosing the right framework units and substituents, these materials could significantly reduce the cost of CO2 capture making CCS practical. Presently, the information available to formulate rational design principles for these materials is limited due to the arduous synthesis and testing of these materials. In that regard, the current proposal tackles these key challenges, specifically with respect to the testing of CO2 capture by the aforementioned porous materials. The requested funding will be used to acquire a high pressure gas adsorption analyzer that will provide the necessary measurement capabilities, which will be unique in Canada. Moreover, the equipment will enable the researchers to examine materials suitable not only for post-combustion CO2 capture, but also pre-combustion CO2 capture and hydrogen generation, which are expected to be a key technologies for future clean power generation and storage.

气候变化可以说是我们这一代人中最大的挑战，减轻二氧化碳排放的需求是紧迫的。由于燃烧化石燃料的发电量占全球二氧化碳排放量的40％，因此几乎所有严重的温室降温策略都包括碳捕获和储存（CCS）作为该计划的关键组成部分。迄今为止，大规模CCS尚未实现，这在很大程度上是因为将二氧化碳与烟气与当前技术分开需要过多的能量。因此，实施此类技术将导致电力成本增加60-80％。为了解决这些问题，纳米多孔金属有机框架（MOF）和价值有机框架（COF）引起了很多关注，因为它们有可能由于其创纪录的内部表面积和高度可调的性质而代表节能的二氧化碳洗涤器。研究表明，通过选择正确的框架单元和取代基，这些材料可以显着降低二氧化碳捕获的成本，从而使CCS实用。目前，由于这些材料的艰巨合成和测试，可用于制定这些材料的理性设计原理的信息受到限制。在这方面，当前的提案应对这些关键挑战，特别是在上述多孔材料对CO2捕获的测试方面。要求的资金将用于获得高压气体吸附分析仪，该分析仪将提供必要的测量功能，这在加拿大将是独一无二的。此外，设备将使研究人员能够检查不仅适用于燃烧后二氧化碳捕获的材料，还可以检查燃烧前的二氧化碳捕获和氢生成，这预计将是未来清洁电力发电和存储的关键技术。
