Hydrogen-halogen energy storage system: preliminary feasibility and economic assessment
The hydrogen-chlorine (H/sub 2/-Cl/sub 2/) cell has been suggested as an electric energy storage battery. Recently, this system was proposed for energy storage applications in electric utilities with the following advantages over the batteries and the hydrogen-oxygen (H/sub 2/-O/sub 2/) system which are being considered for the same purpose: (1) since the electrode reactions of H/sub 2/ and Cl/sub 2/ are quite reversible, one can expect an overall efficiency (electric ..-->.. electric) of over 75 percent; (2) the same electrodes can be used as electrocatalysts in both modes (chemical and electricity generation). Therefore, the same electrochemical cell can be used for both functions, which reduces the capital costs; (3) the reactants for chemical and electricity generation are stored outside the cell which appears beneficial for a weekly cycle. A preliminary technical and economic feasibility assessment of the hydrogen-halogen battery as an electric energy storage system was undertaken and results are presented.
