From the perspective of life cycle cost analysis, this paper conducts an economic evaluation of four mainstream energy storage technologies: lithium iron phosphate battery, pumped storage, compressed air energy storage, and hydrogen energy storage, and quantifies and compares the life cycle cost of multiple energy storage technologies.
Does storage duration affect the cost of energy?
We found that, because of economies of scale, the levelized cost of energy decreases with an increase in storage duration. In addition, performance parameters such as round-trip efficiency, cycle life, and cycle length highly influence the final costs and environmental footprints of various storage technologies.
Does uncertainty affect the life cycle costs of electro-chemical storage systems?
Battke et al. reviewed the impact of uncertainty in the inputs on the life cycle costs of electro-chemical storage systems, focusing on four types of battery systems, lithium-ion, lead-acid, sodium-sulfur, and vanadium-redox flow . The review did not include mechanical, hydrogen, or thermal energy storage technologies.
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.
