Looking at 100 MW systems, at a 2-hour duration, gravity-based energy storage is estimated to be over $1,100/kWh but drops to approximately $200/kWh at 100 hours. Li-ion LFP offers the lowest installed cost ($/kWh) for battery systems across many of the power capacity and energy duration combinations.
Cost information for various gravity-based storage systems was obtained directly from developers. For brick-based storage systems, cost and performance information was obtained for a single power output (10 MW) with two different energy outputs (40 and 2,40 MWh) (Terruzzin, 2021).
For Gravity Storage systems, the levelized cost of storage decreases as the system size increases. Based on the system cost, GES with an energy storage capacity of 1 GWh, 5 GWh, and 10 GWh has an LCOS of 202 US$/MWh, 111 US$/MWh, 92 US$/MWh, respectively. This can be explained by the fact that the system CAPEX decreases with an increased capacity.
