Abstract:
A compressed air storage power generation apparatus is provided with a motor, a compressor, a pressure accumulation tank, an expander, a generator, a first heat exchanger and a cold heat extracting unit. The motor is driven by input power generated using renewable energy. The compressor is mechanically connected to the motor and compresses air. The pressure accumulation tank accumulates the compressed air compressed by the compressor. The expander is driven by the compressed air supplied from the pressure accumulation tank. The generator is mechanically connected to the expander. The first heat exchanger exchanges heat between the compressed air supplied from the compressor and a heat medium and cools the compressed air to room temperature. The cold heat extracting unit extracts air serving as working fluid as cold air of the room temperature or lower. Due to this configuration, the compressed air energy storage power generation apparatus capable of smoothing input power that varies irregularly and efficiently performing heating and cooling with the input power is provided.

Claim (Index 8):
A compressed air energy storage power generation method comprising:\n compressing air with irregularly fluctuating input electric power; cooling the compressed air increased in a temperature in the compressing step to a near room temperature; storing the compressed air cooled to near the near room temperature; and expanding the stored compressed air to be used for power generation and cooling down the compressed air to the room temperature or lower at the same time to be extracted as cold air.
