Economic evaluation of compressed air energy storage

Is compressed air energy storage a feasible energy storage solution?

Underlines CAES's importance as a feasible energy storage solution for RES. Compressed air energy storage (CAES) is a large-scale energy storage system with long-term capacity for utility applications. This study evaluates different business models' economic feasibility of CAES pre-selected reservoir case studies.

Can compressed air energy storage help balancing electricity supply and demand?

Compressed air energy storage (CAES) could play an important role in balancing electricity supply and demand when linked with fluctuating wind power. This study aims to investigate design and operation of a CAES system kg), generate more electricity (76.00 MWh) and provide longer discharging time than that at constant shaft speed mode.

How efficient is a compressed air energy storage system?

The results show that the round-trip efficiency, energy storage density, and exergy efficiency of the compressed air energy storage system can reach 68.24%, 4.98 MJ/m 3, and 64.28%, respectively, and the overall efficiency of the whole integrated system improves by 1.33%. 1. Introduction

Is compressed air energy storage data confidential?

The data that has been used is confidential. Succar S, Williams R. Compressed air energy storage : theory, resources, and applications for wind power. Princeton University; 2008.

How does a compressed air energy storage system work?

In a compressed air energy storage system, electricity is used to drive compressors to compress the air during the charging process, and during the discharge process, the compressed air is expanded in turbines to generate electricity .

Can a compressed air energy storage system be integrated with a water electrolysis system?

Energy, exergy, economic, and parametric analyses are deeply evaluated. In this paper, a novel compressed air energy storage system is proposed, integrated with a water electrolysis system and an H 2 -fueled solid oxide fuel cell-gas turbine-steam turbine combined cycle system.
