  • Compressed air energy storage system having a standby warm keeping system including an electric air heater
    Patent number: 6848259
    Abstract: A compressed air energy storage system comprises a cavern (1) for stored compressed air and a system for providing the compressed air to a power train (3, 5), this system including a recuperator (7) and a first valve arrangement (8) that controls the flow of the compressed air from the recuperator and to the power train (3, 5). A system for warm-keeping of the power train (3, 5) during stand-by operation of the compressed air energy storage system comprises the recuperator (2) and/or an auxiliary electrical air heater (11) and a second valve arrangement (10, 13) for controlling the airflow for warm-keeping. The system for warm-keeping of the power train allows improved temperature control and avoids disadvantages associated with a warm-keeping system having a combustor.
