Assignee: VOLTA ENERGY, INC.
Field: Electrical machinery, apparatus, energy (Electrical engineering)
Classification: CPC H  Y | IPC H

Claim 8:
9. A system comprising:
a source of alkaline negative electrolyte configured to produce CO2-bearing anions;
a source of acidic positive electrolyte, the alkaline negative electrolyte and the acidic positive electrolyte further comprising redox active molecules that participate in redox reactions to store electrical energy; and
a plurality of flow electrochemical cells in fluid communication with the sources of electrolyte, the flow electrochemical cells comprising:
a negative electrode,
a positive electrode,
two ion-exchange membranes in contact with the negative electrode and the positive electrode, respectively, and
an intermediate neutralyte layer between the two ion-exchange membranes, the CO2-bearing anions transported to the neutralyte layer, via ion migration through the first ion-exchange membrane, or by pump transport of the alkaline negative electrolyte, to react with protons and thereby release the CO2 as a gas,
wherein the flow electrochemical cells are configured for simultaneous CO2 capture and electrical energy storage.
