| Abstract Scope |
The concept of direct CO2 capture and conversion has attracted significant interest from industries and academia in recent decades due to its potential to address the current grand challenge of global warming/climate change, rapid depletion of fossil fuels and realization of a future carbon neutral ecosystem. The incumbent benchmark technology for CO2 capture is the post-combustion flue-gas “amine washing”, which is energy intensive and costly for large-scale commercial implementation. The CO2 conversion technologies, on the other hand, are still at their infancy with many technical challenges to overcome, but primarily being explored in laboratory-scale, low-temperature, solution-based and high-temperature, solid-oxide-based electrochemical cells with renewable electricity perceived as the energy input. In this presentation, we provide a high-level overview on recent progress in high-temperature electrochemical CO2 transport membranes that can capture and convert CO2 into valuable chemicals in single catalytic reactor fashion, including chemistry and transport theory, functional materials, reactors, and challenges. |
