Exergy Analysis of Adiabatic Liquid Air Energy Storage (A-LAES) System Based on Linde–Hampson Cycle

Efficiently storing energy on a large scale poses major challenge and one that is growing in importance with the increasing share of renewables mix. The only options at present are either pumped hydro or compressed air storage. One novel alternative to store using liquid air, but this technology not yet fully mature requires substantial research development, including in-depth exergy analysis. This paper presents an analysis Adiabatic Liquid Air Energy Storage (A-LAES) system based Linde–Hampson cycle. was carried out for four cases different parameters, particular discharge pressure inlet turbine (20, 40, 100, 150 bar). results show greatest destruction can be observed evaporator Joule–Thompson valve. In case evaporator, lowest pressure, i.e., 20 bar, reaches over 118 MWh/cycle. It decreases down approximately 24 MWh/cycle which caused by decrease heat vaporization air. valve, changes reversed. highest considered (150 bar) amounts 183 as lowered 57.5 bar. other components do greater than 50 all pressures. Specific liquefaction work ranged from 0.189 kWh/kgLA 0.295 efficiency 44.61% 55.18%.
