Fig. 5: The performance of DREC system under different current densities.
From: Continuous decoupled redox electrochemical CO2 capture
A Electrolysis durability test at a constant current density of 10 mA cm−2 for simulated flue gas capture for a total period of 200 h. B Absorption efficiencies at different current densities. C Desorption efficiencies at different current densities. D Carbon removal efficiency of DREC system at different current densities. The carbon removal efficiency is calculated using Eq. 5. The error bars indicate that each group was subjected to three repeated experiments. E Energy consumption of DREC system at different current densities. The energy consumption is calculated using Eq. 8.
