The UK Government has an ambitious target to reduce CO2 emissions by 80% by 2050, where Carbon Capture and Storage (CCS) together with bioenergy are critical for the UK to meet its reduction targets, whilst delivering affordable, secure and sustainable energy.  However, significant challenges remain in growing CCS from the megaton level on CO2 emissions reductions, where it is today, to the gigaton level where it needs to be to help mitigate global climate change. These challenges include the efficiency and capital cost penalties associated with CO2capture, which are hindering the deployment of CCS. The advancement of sorption-based technologies for capturing CO2 from power plants and large industrial facilities has attracted a lot of interest in recent years. Some of the main advantages of a sorption-based process over the conventional amine scrubbing process include low regeneration energy requirements, no liquid waste and a much wider range of possible operating temperature (typically ranging from ambient temperature to 700°C). 
In the past few years, our group has engaged in the development of novel solid sorbents for CO2 capture with superior performance and desirable economics. This seminar will provide an overview of our research – past and current – in that field. I will present selected examples of our work, where our group’s approach encompasses not only materials synthesis but also characterization, lab-scale performance testing, process intensification and process modelling including process integration and optimisation. By establishing the materials composition-structure-performance relationship and by anticipating the required process performance, we can ultimately provide guidance for the development of more advanced, next-generation materials for cost-competitive and efficient separation processes in energy, industrial and environmental applications.
