6 FAQs about [Supplementary combustion air energy storage system]

What is compressed air energy storage?

Cogeneration is a technology related to energy efficiency, but it is not enough to deal with the integration of renewable sources to the grid and meeting fluctuating demands. Compressed air energy storage is a promising technology that can be aggregated within cogeneration systems in order to keep up with those challenges.

Can compressed air energy storage be combined with cogeneration?

Compressed air energy storage is a promising technology that can be aggregated within cogeneration systems in order to keep up with those challenges. Here, we present different systems found in the literature that integrate compressed air energy storage and cogeneration. The main parameters of performance are reviewed and analyzed.

What is a thermal energy storage system?

Heat from compression is stored in a thermal energy storage system (Fig. 2) for pre-heating the air before the expansion or supplying heat for users . The cold air from the expansion is used for cooling the intermediate stages of the compressor or to meet cooling demands.

Why are energy storage systems a promising solution?

Energy storage systems are a promising solution because the generation period is decoupled from the consumption period . Those systems can store the excess of energy generated in off-peak demand periods for later use when the demand is high (a process called peak shaving or valley filling).

What is thermal energy storage (HT-CAES)?

In Ref. , thermal energy storage is used to drive a turbocharger that provides supplementary airflow for the turbine in the expansion process. The system was named by the author as Hybrid Thermal and Compressed Energy Storage (HT-CAES) and achieves a RTE of 24.5%–54.5%.

What are the components of a compressed air system?

It consists of a compression train, an expansion train, air storage cavern, saturator, air preheater, water preheater and water circulatory system. The compression train is driven from renewable sources or power grid.
