The evaluations of the energy storage density, system efficiency and power output, under the effects of insufficient charging/discharging, are presented in Fig. 8, Fig. 10, Fig. 12. The results demonstrate that the actual performance of density and power, except for the system efficiency, could highly deviate from the targets at design conditions.
However, the effects of insufficient charging and discharging, due to the variability of renewable energy have not been investigated before. The output power and the energy density evaluated in the present work could be incorporated with future work of techno-economic analysis.
A clearly defined sufficient charging/discharging at design conditions is a point in the phase space (noted by the star in green), while the rest of the space can be referred to as “off-design conditions”. For example, two dashed curves are given for off-design charging and discharging.
