The capital costs of these resulting flow batteries are compared and discussed, providing suggestions for further improvements to meet the ambitious cost target in long-term.
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.
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.
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.
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.
Flow batteries have a unique selling proposition in that increasing their capacity doesn’t require adding more stacks—simply increasing the electrolyte volume does the trick. This aspect potentially reduces expansion costs considerably when more energy capacity is needed.
By 2030, total installed costs could fall between 50% and 60% (and battery cell costs by even more), driven by optimisation of manufacturing facilities, combined with better combinations and reduced use of materials. Battery lifetimes and performance will also keep improving, helping to reduce the cost of services delivered.
