Abstract: An apparatus for removing an acid gas from a feed gas stream includes an absorber and an electrochemical regenerator. The absorber is adapted for separating the acid gas from the feed gas feed stream using a lean carbon capture solvent. The electrochemical regenerator is connected to the absorber and adapted for (a) regenerating the carbon capture solvent and (b) generating hydrogen gas. A method for removing acid gas from a feed gas stream includes steps of separating, delivering, releasing, generating and returning.
