Flow batteries also boast impressive longevity. In ideal conditions, they can withstand many years of use with minimal degradation, allowing for up to 20,000 cycles. This fact is especially significant, as it can directly affect the total cost of energy storage, bringing down the cost per kWh over the battery's lifespan.
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.
Non-battery systems, on the other hand, range considerably more depending on duration. 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.
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). From this information, costs were extrapolated for the various energy and power levels considered in this study by solving two linear equations.
For those seeking long-duration energy storage or tailored power solutions, flow batteries offer a promising option. So, it''s not just about the upfront cost per kWh, but understanding the
