Exploring the scope of capacitance-assisted electrochemical carbon dioxide capture†
Optimisation of a capacitance-assisted electrochemical carbon-capture process is facilitated by the physical separation of the graphite and aluminium anode electrodes. This facilitates graphite electrode recycling and enables high current and increased aluminium surface area experiments which fix carbon at a higher rate and the same cell-voltage. Quantification of the H2 cathode byproduct shows that this process could be a net energy producer if recycled aluminium is used as the sacrificial anode.
