Title: Thermal Analysis of of Near-Isothermal Compressed Gas Energy Storage System

In this paper, alternative system configurations for a novel Ground-Level Integrated Diverse Energy Storage (GLIDES) system, which can store energy via input of electricity and heat and deliver dispatchable electricity, is presented. The proposed system is low-cost and hybridizes compressed air and pumped hydro storage approaches that will allow for the off-peak storage of intermittent renewable energy for use during peak times. This study reveals that implementing direct-contact low grade heat exchange via sprayed falling droplets to cool the gas during charging (compression) and warm the gas during discharging (expansion) can be achieved through a secondary recirculating loop of liquid. This study shows that if the recirculating liquid loop is pre-conditioned with waste-heat prior to spraying during gas expansion and considering all the round trip conversion losses from standard 120 V 60 HZ electricity input and output with utilization of low grade heat at 90 C the alternative system design leads to a 16% boost in round trip efficiency of the electricity storage to elec = 82% with an energy density of ED = 3.59 MJ/m3.
