Can a compressed air energy storage system achieve pressure regulation?

In this paper, a novel scheme for a compressed air energy storage system is proposed to realize pressure regulation by adopting an inverter-driven compressor. The system proposed and a reference system are evaluated through exergy analysis, dynamic characteristics analysis, and various other assessments.

How do compressed air storage systems use energy?

The modeled compressed air storage systems use both electrical energy (to compress air and possibly to generate hydrogen) and heating energy provided by natural gas (only conventional CAES). We use three metrics to compare their energy use: heat rate, work ratio, and roundtrip exergy efficiency (storage efficiency).

What is compressed air energy storage (CAES)?

Compressed air energy storage (CAES) is an effective solution for balancing this mismatch and therefore is suitable for use in future electrical systems to achieve a high penetration of renewable energy generation.

Is compressed air energy storage a potential large-scale energy storage technology?

Thermodynamic performance assessment of the proposed system was analysed. The purchased-equipment costs and parametric sensibility analysis were implemented. Compressed air energy storage is considered to be a potential large-scale energy storage technology because of its merits of low cost and long design life.

What is a conventional compressed air energy storage system?

Schematic of a generic conventional compressed air energy storage (CAES) system. The prospects for the conventional CAES technology are poor in low-carbon grids [2,6–8]. Fossil fuel (typically natural gas) combustion is needed to provide heat to prevent freezing of the moisture present in the expanding air .

Can compressed air energy storage system be integrated into coal-fired power plant?

Compressed air energy storage system is integrated into coal-fired power plant. The possible system coupling schemes were discussed. Thermodynamic performance assessment of the proposed system was analysed. The purchased-equipment costs and parametric sensibility analysis were implemented.
