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.
Compressed air energy storage may be stored in undersea caves in Northern Ireland. In order to achieve a near- thermodynamically-reversible process so that most of the energy is saved in the system and can be retrieved, and losses are kept negligible, a near-reversible isothermal process or an isentropic process is desired.
Compressed air energy storage has a significant impact on the energy sector by providing large-scale, long-duration energy storage solutions. CAES systems can store excess energy during periods of low demand and release it during peak demand, helping to balance supply and demand on the grid.
This compressed air is then stored in large underground caverns, aquifers, or above-ground tanks. The compression process generates heat, which can also be captured and stored using heat exchangers to improve the system's overall efficiency. When electricity demand is high, the compressed air is released from the storage reservoir and heated.
The air, which is pressurized, is kept in volumes, and when demand of electricity is high, the pressurized air is used to run turbines to produce electricity . There are three main types used to deal with heat in compressed air energy storage system .
Compressed air energy storage could be a valuable tool in allowing us to hit these ambitious targets. Spare Electricity within the grid is used to compress and store air under pressure, which can then be released on demand to make electricity.
