Are flow batteries worth it?
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.
How long do flow batteries last?
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.
How do you calculate a flow battery cost per kWh?
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.
