Electrochemical carbon dioxide converter and liquid regenerator

A carbon dioxide conversion system for an environment that is ambient gas, comprising:

• a scrubber downstream of the environment;
• an electrochemical conversion cell downstream of the scrubber;
• an ionic liquid storage intermediate the scrubber and the electrochemical conversion cell;
• a stripper intermediate the electrochemical conversion cell and the ionic liquid storage, wherein,
• wherein:
• the scrubber is configured to receive gas containing carbon dioxide from the environment, receive cleaned liquid absorbent from the ionic liquid storage, and discharge at least one of Ar, N2, and CO to the environment, and
• the stripper is configured to (i) use water vapor as a sweep gas,
• (ii) discharge cleaned liquid absorbent to the ionic liquid storage, and (iii) discharge methane to a methane storage.
