A novel energy storage technology for the integration of variable renewable energy is investigated in this work. The energy is stored as thermal energy at high-temperature in a packed bed of low-cost natural rock. Electrically heated air is used for charge and a heat recovery steam generator, which can supply steam to a turbine or other consumers, for discharge. The investigation includes dynamic system simulation of the air cycle as well as computational fluid dynamics on packed-bed and particle scale. The energy-based air cycle efficiency as well as the ratio of usable to nominal thermal storage capacity are derived for a selection of test cases.
