The intermittent electricity production from solar energy causes an increase in the need for energy storage technology. This research aims to determine the effect of piston mass on the charging efficiency of compressed air-gravity energy storage (CA-GES) in solar power plant applications. This research was conducted through experiments with a CA-GES prototype connected to an energy source from a solar power plant. The mass of the piston varied by 0.3 kg, 0.7 kg, and 2 kg, and the solar power source varied by 14.4 W, 15.5 W, and 22.6 W input power, with the target pressure on the CA-GES tank side of 2 bar. The results showed that the highest efficiency of 67% was obtained at an input power of 14.4 W and a piston mass of 2 kg. As the piston mass increases, the charging efficiency increases, increasing the stored electrical energy in the CA-GES energy storage system. © Published under licence by IOP Publishing Ltd.
