A Review of Compressed Air Energy Storage Technology for Renewable Energy Storage in the Sudano-Sahelian Zone of Nigeria

Abstract

Electrical energy storage has been identified as the basic founding technology to meet the challenges in the power network due to the rapidly increasing penetration of renewable energy. Compressed Air Energy Storage (CAES) has gained substantial worldwide attention in recent years due to its low cost and high reliability in large-scale energy storage systems. Reviews of different CAES technologies were discussed; Small-scale CAESs are more suitable for integration with renewable energy for backup, load following and uninterruptible power supply. Wind and solar energy technologies in the Sudano-Sahelian Zone were also presented. The potential of both wind and solar energy in the study area is highly sufficient for electrical power generation and storage. The paper provided essential and critical information for CAES plant planning and building. The regeneration of the stored renewable Energy electrical energy from the compressed air was also presented.
