Claim 12:
13. An electrochemical ocean alkalinity enhancement (OAE) system comprising:
a BPED system comprising:
a buffering system comprising an acid buffer tank configured to store an acid solution,
an electrodialysis apparatus comprising at least one salt chamber, at least one acid chamber, at least one base chamber, and
a flow control system comprising a plurality of flow lines connected between the buffering system and the electrodialysis apparatus; and

a control circuit configured to control the SPED to perform base generating operations during first time periods and descaling maintenance operations during second time periods, wherein:
during each said base generating operation, the control circuit controls the flow control system to direct a salt stream through the at least one salt chamber, to direct an acid stream comprising at least a portion of the acid solution from the acid buffer tank through the at least one acid chamber, and to direct a base stream through the at least one base chamber, and the control circuit controls the electrodialysis apparatus to electrochemically process the salt stream passing through the at least one salt chamber in a way that increases an amount of acid in the acid stream and an amount of base substance in the base stream; and

during each said descaling maintenance operation, the control circuit controls the flow control system to direct the acid stream from the acid buffer tank through the at least one salt chamber and the at least one base chamber.
