Data underlying the publication: Efficiency and energy consumption analysis of bipolar membrane electrodialysis for electrochemical CO2 capture

This dataset contains data collected during experiments with bipolar membrane electrodialysis employed for carbon capture. The objective of the research was to investigate the efficiency and energy consumption of alkaline solvents regeneration through bipolar membrane electrodialysis (BMED), a process employed for carbon capture. A laboratory-scale BMED system was operated under various conditions, including changes in rich solvent carbon loading, potassium load ratio, and applied current density. Numerous liquid and gas samples were collected and analyzed during the experiments. BMED performance was evaluated based on the following parameters: CO₂ flow rate; pH of the acidic and alkaline compartments; potassium concentration in the influent and acidic compartments; total inorganic carbon concentration in the influent, acidic, and alkaline compartments; applied current density; measured total voltage; and anode and cathode potentials. This research data is being made public to serve as supplementary data for this publication and to allow other researchers to use it in their own work. This work was performed at Wetsus, European Centre of Excellence for Sustainable Water Technology.
