Electrochemical methods of sequestering co2

A system comprising:

• a) a reactor configured to produce a CO2-charged solution from
• 1) a gaseous waste stream comprising carbon dioxide and
• 2) a solution of sodium hydroxide;
• b) an electrochemical system configured to produce the solution of sodium hydroxide and provide it to the reactor;
• and
• c) a gas conveyer configured to convey the gaseous waste stream to the reactor from a source of the gaseous waste stream.

A system comprising:

• a) a reactor for producing a CO2-charged solution from an industrial source of CO2 and
• b) an electrochemical system comprising an anode and a cathode,
• wherein the electrochemical system is configured to produce hydroxide at the cathode without producing gas at the anode, and further
• wherein the electrochemical system is configured to provide the hydroxide to the reactor.

A system comprising:

• a) a reactor for producing a CO2-charged solution from an industrial source of CO2 and
• b) an electrochemical system comprising an anode and a cathode,
• wherein the electrochemical system is configured to produce hydroxide at the cathode when the voltage across the anode and the cathode is less than 2.0 V, and further
• wherein the electrochemical system is configured to provide the hydroxide to the reactor.
