With global energy demand predicted to rise as the world population increases, there is a serious challenge to ensure energy security and also to reduce CO2 emissions. Atmospheric CO2 levels will reach about 800 ppm by 2100 resulting in about 4 C rise in the earth surface temperature if no action is taken (CO2 Earth 2017). At the 21st Conference of Parties (COP21) to the United Nations Framework Convention on Climate Change (UNFCCC) held in Paris, France from 30th November to 12th December 2015, 195 nations historically agreed to ‘‘combat climate change and unleash actions and investment towards a low carbon, resilient and sustainable future’’ with the aim to ensure global temperature rise is kept well below 2 C (UNFCCC 2015). To achieve this aim, a portfolio of technologies have been proposed, one of which is carbon capture, utilization and storage (CCUS) (Dixon 2016). CCUS comprises of CCS and CCU, both of which involve capture of CO2 from various sources such as large stationary power plants (Cuéllar-Franca and Azapagic 2015). However, they differ in the destination of the captured CO2: (1) in CCS, CO2 is transported and injected into underground storage sites; (2) CO2 is converted to commercial products in CCU. The energy trilemma including energy security, energy affordability and environmental sustainability makes CCUS the most probable technology for reducing emissions from power plants and carbon intensive industries (IPCC 2014). Without CCUS, mitigation cost is predicted to be as high 138% as shown in Table 1. CCUS has attracted a great deal of research interest worldwide in recent years. Most research in the context of CCUS focuses on carbon capture since it offers the biggest challenges in terms of capital and operating cost contributing about 70%–80% of the total cost of the full CCUS network including capture, transport conversion/storage (Leung et al. 2014). CO2 capture is broadly classified into pre-combustion, post-combustion and oxy-fuel carbon capture approaches (Rubin et al. 2015). This is summed up in Fig. 1. In the different approaches, there are different processes for separating CO2 from gas mixtures such as chemical absorption, physical absorption, adsorption and membrane separation (Wang et al. 2011). Post-combustion based on chemical absorption is the most promising and also mature technologies because it uses very familiar technologies, retrofits more easily to existing power plants and there are already many demonstration projects across the world. The purpose of this special issue is to create a platform for scientists, engineers and practitioners to present their latest theoretical and technological advancements on carbon capture. In 2013, the EU International Research Staff Exchange Scheme (EU IRSES) funded an international collaboration project between partners in European and Chinese Universities namely the University of Sheffield (UK), the University of Hull (UK), Newcastle University (UK), University of Valenciennes and Hainaut-Cambresis (UVHC, France), Tsinghua University (China), East China University of Science and technology (ECUST, China) and SouthEast University (China).
