摘要： Provided is an energy storage device, including: a first heat exchanger configured to exchange heat between gas and solid particles; a gas supplier configured to supply gas to the first heat exchanger; a heater configured to consume power to heat any one of or both of gas fed from the gas supplier to be supplied to the first heat exchanger and gas present in the first heat exchanger; a solid-gas separator configured to separate gas and solid in a solid-gas mixture discharged from the first heat exchanger; a high-temperature tank and a low-temperature tank each configured to store the solid particles separated by the solid-gas separator; a first heat utilization device configured to use thermal energy of the gas separated by the solid-gas separator; a high-temperature particle supplier configured to supply the solid particles stored in the high-temperature tank to the first heat exchanger; and a low-temperature particle supplier configured to supply the solid particles stored in the low-temperature tank to the first heat exchanger.
