Assessing the value of battery energy storage in future power grids
The paper found that in both regions, the value of battery energy storage generally declines with increasing storage penetration. "As more and more storage is deployed, the value of additional storage steadily falls," explains Jenkins. "That creates a race between the declining cost of batteries and their declining value, and our paper ...
Battery cycle life vs ''energy throughput''
A typical lithium-ion battery, for example, will typically have a cycle life of 4000-8000 cycles, while low-end lead acid batteries could have cycle lives as short as 800-1,000 cycles. Generally speaking, the more you cycle a battery, the more its ability to hold a charge is diminished (the exception if flow batteries like those from Redflow.)
