Executive Summary In this work we describe the development of cost and performance projections for utility-scale lithium-ion battery systems, with a focus on 4-hour duration
The vanadium redox flow battery (VRFB) is arguably the most well-studied and widely deployed RFB system. At the time of writing, there are approximately 330 MW of VRFBs
The power modules for a 4-hour system are the same for a 12-hour system, so the incremental cost of adding duration/energy to a flow battery is tied to the addition of electrolyte to the system. 1.

Abstract This report defines and evaluates cost and performance parameters of six battery energy storage technologies (BESS) (lithium-ion batteries, lead-acid batteries, redox flow batteries,
Energy storage addresses the intermittence of renewable energy and realizes grid stability. Therefore, the cost-effectiveness of energy storage systems is of vital importance,
However, the key to unlocking the potential of flow batteries lies in understanding their unique cost structure and capitalizing on their distinctive strengths. It’s clear that the cost per kWh of flow batteries may seem high at first glance. Yet, their long lifespan and scalability make them a cost-effective choice in the long run.
While this might appear steep at first, over time, flow batteries can deliver value due to their longevity and scalability. Operational expenditures (OPEX), on the other hand, are ongoing costs associated with the use of the battery. This includes maintenance, replacement parts, and energy costs for operation.
Provided by the Springer Nature SharedIt content-sharing initiative The economic viability of flow battery systems has garnered substantial attention in recent years, but technoeconomic models often overlook the costs associated with electrolyte tanks.
Existing commercial flow batteries (all-V, Zn-Br and Zn-Fe (CN) 6 batteries; USD$ > 170 (kW h) −1)) are still far beyond the DoE target (USD$ 100 (kW h) −1), requiring alternative systems and further improvements for effective market penetration.
This includes maintenance, replacement parts, and energy costs for operation. Flow batteries, with their inherent advantageous design, have less stringent temperature and cycling requirements, potentially reducing OPEX compared to other technologies. A critical determining factor in the cost per kWh of flow batteries is the system’s lifespan.
As we can see, flow batteries frequently offer a lower cost per kWh than lithium-ion counterparts. This is largely due to their longevity and scalability. Despite having a lower round-trip efficiency, flow batteries can withstand up to 20,000 cycles with minimal degradation, extending their lifespan and reducing the cost per kWh.
