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.
When discharging, the stored chemical energy gets converted back to electricity. The external storage allows for independent scaling of power and energy, which is a defining feature of flow batteries. A key advantage of this kind of battery is its ingenious ability to increase energy capacity.
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.
Let’s look at some key aspects that make flow batteries an attractive energy storage solution: Scalability: As mentioned earlier, increasing the volume of electrolytes can scale up energy capacity. Durability: Due to low wear and tear, flow batteries can sustain multiple cycles over many years without significant efficiency loss.
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.
Flow batteries also boast impressive longevity. In ideal conditions, they can withstand many years of use with minimal degradation, allowing for up to 20,000 cycles. This fact is especially significant, as it can directly affect the total cost of energy storage, bringing down the cost per kWh over the battery’s lifespan.
