CO2 Footprint and Life‐Cycle Costs of Electrochemical Energy Storage
This study presents a probabilistic economic and environmental assessment of different battery technologies for hypothetical stationary energy storage systems over their
Theinherentphysicalandchemicalpropertiesofbatteriesmakeelectrochemicalenergy storage systems suffer from reduced lifetime and energy loss during charging and dis- charging. These problems cause battery life curtailment and energy loss, which in turn increase the total cost of electrochemical energy storage.
Keywords:Electrochemical energy storage · Life-cycle cost · Lifetime decay · Discharge depth 1 Introduction Electrochemical energy storage is widely used in power systems due to its advantages of high specific energy, good cycle performance and environmental protection .
The operation and maintenance costs of electrochemical energy storage systems are the labor,operationandinspection,andmaintenance coststoensurethattheenergystorage system can be put into normal operation, as well as the replacement costs of battery fluids and wear and tear device, which can be expressed as:
In order to evaluate the cost of energy storage technologies, it is necessary to establish a cost analysis model suitable for various energy storage technologies. The LCOS model is a tool for comparing the unit costs of different energy storage technologies.
