Thermodynamic and Economic Analysis of a Trigenerative Adiabatic Compressed Air Energy Storage
Year: 2024
Type: conference-paper
Abstract: Energy storage is indispensable for decarbonising power systems with high penetration of fluctuating renewable generation (e.g., wind, solar). In this study, an innovative trigeneration adiabatic compressed air energy storage (Tri-ACAES) system that produces heating, cooling, and electricity is proposed. The Tri-ACAES system can absorb more wind power than an ACAES system. The Tri-ACAES can work in heating and cooling mode when renewable generation is too low to charge the ACAES system due to the off-design characteristics of the compressor. The results reveal that the round-trip efficiency and turbine power output of the proposed Tri-ACAES system are enhanced by up to 5.8% and 33%, respectively than conventional ACAES system. Further, the proposed system reduced the cost of thermal energy storage by up to 60% than conventional ACAES system.
