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.
It’s integral to understanding the long-term value of a solution, including flow batteries. Diving into the specifics, the cost per kWh is calculated by taking the total costs of the battery system (equipment, installation, operation, and maintenance) and dividing it by the total amount of electrical energy it can deliver over its lifetime.
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.
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.
