AQDSH 2 refers to the reduced form of AQDS. The technology could fundamentally transform the way electricity is stored on the grid, making power from renewable energy sources such as wind and sun far more economical and reliable. Cell schematic. Discharge mode is shown; the arrows are reversed for electrolytic/charge mode.
