Advanced Compressed Air Energy Storage integrates thermochemical recuperation, where direct heat transfer is achieved between gas and solid. Both known and hypothetical redox reactions are considered. This integration enables a more stable turbine inlet temperature, leading to longer storage durations and higher round trip efficiencies.
The developed systems are analyzed based on the first and second laws of thermodynamics. Results indicate that heat recovery in the air compression process has great potential to improve the system performance. Heat storage option is included in the develped systems to provide opportunity for later use.
The energy recovered from the compressed air system forms a supplementary heat source that reduces the load on the boiler, saves heating fuel and could potentially result in the use of a smaller boiler. Prerequisites for energy recovery from compressed air compressors differ in part depending on the type of compressor.
The amount of the recovered heat increases with the increasing air flow rate as the cooling demand of the air increases. When the total energy flows for all system is considered, compressors cover 53% of the total power energy flows. While 32% of total energy flows occurs via the generator, the useful heat outputs cover its 15%.
Compressed Air Energy Storage (CAES) is a method of energy storage. It suffers from low energy and exergy conversion efficiencies (ca. 50% or less) due to the inherent losses in compression, heat loss during storage, and the commonly employed natural gas-fired reheat prior to expansion.
Compressed air energy storage (CAES) is considered a grid-scale electricity storage method; however, it suffers from inherent inefficiencies, specifically the loss of heat produced during compression.
