Grid-Scale Storage of Electrical Energy

Cycle efficiency High benchmark small scale capacitors close to 100%, grid scale pumped hydro 80% [Pg.40]

Power density High often opposite to energy density [Pg.40]

Cycle stability High, problematic for various battery types [Pg.40]

Self discharge Ideally zero, highly problematic for flywheels, problematic for some types of battery [Pg.40]

Investment cost Low, but has to be considered together with cycle cost [Pg.40]

Grid-scale electrical energy storage requires that the battery be capable of being charged and discharged in one to two hours. The discharge rate capability of the iron electrode can be improved if the passivation by the electrically non-conductive iron (II) hydroxide can be achieved (107,108). [Pg.104]
