Carbon dioxide capture from point sources or air and electrolysis are two promising processes to circumvent the gigaton challenges in reducing greenhouse gas emissions. Both processes are energy costly.

Synergistically coupling these two processes has the potential to improve the overall energy efficiency and lowering capital costs by avoiding the requirement for carbon dioxide compression and transport and capture media regeneration and resolving critical issues faced by gas conversions such as costly product separation, inefficient carbon utilisation, and stability issues associated with electrode wettability.

The electrochemical conversion for the integration (also known as integrated electrolysis) directly from capture media is the enabling step for this process intensification but is challenging to achieve industrially applicable rates and selectivity.

Our lab seeks to identify the key rate-determining step for integrated electrolysis and attempts to circumvent such critical issues through material and engineering innovations.
