摘要:The paper presents a thermodynamic analysis of a selected hypothetical liquid air energy storage (LAES) system. Theadiabatic LAES cycle is a combination of an air liquefaction cycle and a gas turbine power generation cycle without fuelcombustion. In such a system, heat of compression is stored and subsequently used during the expansion process in theturbine.A mathematical model of the adiabatic LAES system was constructed. Balance calculation for a selected configuration ofthe energy storage system was performed. The influence of pressure in the air liquefaction cycle and the gas turbine powergeneration cycle on storage energy efficiency was analyzed. The results show that adiabatic liquid air energy storage systemscould be very effective systems for storing electrical power, with efficiency levels reaching as high as 57%.
