The primary gaseous products are hydrogen (H₂) and carbon monoxide (CO), forming synthesis-ready syngas. Only minor residual CO₂ is observed, with no detectable C₁ or C₂ hydrocarbon by-products under standard operating conditions. This ensures a clean output stream suitable for downstream synthesis processes.

Because the feedstock is liquid-phase and the electrolyser adopts a zero-gap architecture similar to alkaline water electrolysers, scale-up can be achieved through stack replication. This configuration enables straightforward modular expansion while maintaining electrochemical performance consistency.

The system operates as a CO-focused electrolyser. During electrochemical conversion of the captured CO₂ species to CO, water within the amine solution is simultaneously electrolysed to generate hydrogen. The resulting H₂/CO ratio can be tuned through catalyst selection and applied voltage control, allowing compatibility with different downstream synthesis requirements.

Testing has been conducted using amine-based post-combustion capture solutions containing typical nitrogen- and sulfur-derived species. Under controlled operating conditions, these species do not show measurable impact on electrochemical performance. The platform is therefore compatible with conditioned post-combustion CO₂ capture streams, including industrial flue gas and biogenic sources.
